BMW S55 Owners! Stop Worrying About This!

- When shopping or purchasing your new or used BMW with the S55. I can't stand when people say. Don't use kick down because of the crank hub could fail or don't floor it because of fear of the crank hub failing. This is a rare failure yet people are spending thousands of dollars in upgrading the crank hub bolt. This problem affect maybe 50-100 cars? Out of the thousands of vehicles are there. I'd say that's pretty good. There are lot more serious issues to worry about instead .99% chance this could go wrong. There isn't any link to amount of power or time this part could go bad since it doesn't know the difference between a stock car or tuned car. It's all based on engine timing. Maybe a few cars didn't get the right factory specs and with perfect scenario of high power and high traction, coupled with the abrupt shifting, maybe you would have an issue. But I wouldn't hold your breath. I say send it and enjoy it!

Plot twist: his crank hub has already been done 😂
Thanks for this video! I went from F15 X5 50i to M2 comp.
Man this video is right on time for me. Because I'm thinking of rewarding myself with an M4 and I started seeing all these crank hub issues like wtf. I had vanos issue with my E46 M3, wanted to get an E92 M3 butthe whole rod bearings/Tb actuators thing scared me away. so I ended up gettin a camaro ss. Now I decide on M4 and here comes this whole crank hub thing lol. Geez people just take stuff and run with it. And I don't track my cars or do too many upgrades outside of maybe an intake and exhausts and thats it. I'm glad I did find this video.
Great content. We live in a society today were everybody’s being told to be fearful and everybody else is a keyboard expert. Those two sht storms combined and the Internet can be a frightful place especially for an S55 OE crank hub owner.
Exactly!
Agreed bro agreed
That’s why I always look for people who actually have what I want and take their advice not some keyboard warrior/hearsay
Running stage 1 tune car run perfect ,crank hub issue is way over exaggerated 👍
2015 m4 for about 2 years now. Installed VTT Crank bolt capture plate. Stage 2 93 octane, catless downpipes 493whp/552wtq for 15k miles and now full e85 580whp with no issues
Hi there. Still with only capture plate and stock CH??
At 116,000 miles on a 2015 M4, had a stage 1 tune for a while, upgraded to full bolt on stage 2 93 octane, currently running a stage 2 100octane ( similar to e85 ) for a yr an a half now.....2 fuel injectors have been the only mechanical failure, .....car still 🏃♀️ 🏃♂️ like new...and I do rolls and downshift often ( DCT 7 speed ) no crank hub issues
Mine spun with E85 at 9K miles think it’s just a question of when and if you have a tube you definitely should do it. If you spin it can you afford a new engine? That’s the thing if you can’t afford a 3grand fix you probably can’t afford a new engine just my thoughts.
@@BlakesGarage I have 116,000 miles , if ain't spun now it ain't going too lol
@@BlakesGarage running full e85? Sounds like you're pushing harder then the op. Maybe that's why it spun. Shit luck though either way
Did u use kickdown ? I’m stg2 f82 47k miles
@@jaredprovost5754 no sir just don't do heavy burnouts and stunt driving, [n circles smoking your tires ) I never abused my m4 like that....change your diff and Trans oil around 80k....do the colder range plugs with your stage 2....and just my opinion the big hp tunes on full e85 will hurt that car , unless you do a full fuel system upgrade....thats why I went with 100 octane, didn't need any other upgrades....
Love your content keep it up bro
Thank you!
@@eddiemcars I respect your humbleness and honesty.. be safe and looking forward to seeing more content
Tbh i really needed to hear this video cause i just got an F82 so Thank you for posting this bro because seriously the way the stigma is with the crank hub i feel like i cant even have fun driving my car just STOCK. I get so scared to downshift and sometimes just don't...I didn't wanna go stage 1 without doing it but this helps put me a little more at ease. Great to know your on stage 1 !
I might just do it. I strictly use the car just to get back and forth from work M-F and only use cruise control on those days. I only get on the car on the weekends and even that is only a sometimes, Plus when i do drive I'm not one to downshift to 2nd gear super high in the rpm, i always downshift late to help keep stress off the Crankhub & Engine so hopefully ill be okay on stage 1, pray for ya boy lol
P.S. I never use launch control or kickdown, and never plan too
Yeah don’t be afraid to enjoy your car for what it was built for.
The CH has been blown so far out of proportion I think most people is hearsay.
Sure I know it can break, but if was fragile as it rumored, every M3/M4 out there that used kick down would be broken down on the side of the road. Not every owner is on the forum to know. Only the enthusiast who will shout at the tree tops how their car is broken.
Adding stage 2 with E85. You’re making a lot of power. More that what the car is intended. Something has to give.
@@eddiemcars tru and you think I’m safe goin stage 1 with AA midpipes? Cause anything more than that I wont touch until the crank is done
My M4 is stock and i have tracked the car 3 times and driving it so hard. Its NOT and issue on stock power, if u tune the car then yes, new crankhub or capture plate is the way
@@twbigfoothd269 Well said
how is it going one year later? i hope everything is well.
Great video man! I feel as if crank hub failure happens to those who don't drive their M as intended. Give the thing some rpms on the daily and lots of spirited drives! I do plan on doing mine down the line as I want to go e85 and downpipe but at the moment I'm still going to enjoy my F80.
I wish there was direct link as to the cause of failure. I also find owners also won’t admit fault. I can’t buy the “I was driving and suddenly….” Excuse!
For me I don’t worry and enjoy the car!
I think you are right on the money! Should the Crankhub be a supporting mod for 650+ WHP... YES. Is it a huge flaw ... no. We are spoiled in that these cars will make 700+ WHP, FBO, tuned on 🌽.... there is a point especially with a beast like a F8x that you start modding for reliability but that number is not at stock or stage 1. FYI, I was quoted $7800 with parts and tax here in Houston. I just laughed at them, lol. IF... I have an issue, $7800 is a good down payment on a new 911 or another M3/M4, S55 or newer.
Exactly! No need so spend the money now especially for stock and stage 1 cars.
I think going to E85 or those wanting to make big power. PLus putting that power to the ground, you’ll need fix some weak links.
That's crazy in LA it's like 2200
700whp is not obtainable without new turbos and port injection. Just wanna put that out there but yes i have no problems pushing my f80 stock. I'm also still under warranty but either way i wouldn't have any problems doing it. Otherwise what's the point of buying the car?
Thank you Eddie!
Seems like the only time the crankhub should be considered is if you plan to make close to or upwards of 600hp orrrr if you have a model that has close to 100k miles on it then id consider it, because with the crankhub you get all your preventative maintenance done, you get the oil pan gasket done, valvecover gasket, coolant flush, and much much more, so that could make it well worth it if you plan to keep the car over 100k miles. By the time an S55 gets close to 80k-100k miles all that's gunna need to be done anyways due to seals having to many heat cycles & fluids being old. Hope this helps
Agree💯
I had four F8xs with lots of hard driving manual and dct
I just put a CBC on with a good aftermarket warranty. Fixed other items besides the Crank hub
Should be no problem been on stage two since day one
Same. Stage 2 BM3 91 with Catless dp and intake - 2 years no issue with just a CBC and charge pipes.
Thank you so much for this video. I bought an M4 (2014)a week ago. I was always afraid of the crank hub. This helps me :)
Yeah it’s blown out of proportion. The cases of people spinning them are minimal compared to ones who are shouting to the rooftops about upgrading it.
how many miles you got on it?
Bless you for this video. 🤘🏻🤘🏻🤘🏻
Thanks alot. I thought trough this problem the last months. I want to tune my M3 soon, the thing is - everybody is telling me i should get this done. I understand the problem here, but i think the majority of cars don´t have it. I think it doesnt brake not more often than - lets say - the turbochargers...
But i did further research on bmw partnumbers, i found out that the N55 shares the same parts on the crank hub as the S55 - when you consider how much N55s were built i various types of vehicles (from 1 series to 7 series) and you dont really read a lot about issues on the crank hub. The other side is the forums - in the german forums you dont see a lot people with the problem. anybody is complaining about it, but nearly nobody experienced the issue, they "heard about a friend of the brother from the uncle" that this thing was broken on their car.
It’s not a wear/tear item.
People are scared to use kick down because of this because 1 person used kick down and it happens to them.
The common theme I see is stage 2 with E85 and a sticky tire.
You’re pushing the limits of the motor and something has to go somewhere. I don’t think anyone full understands how or why it brakes.
Stock enjoy your car
Stage 1 enjoy your car
Stage 2 and beyond. Proceed with caution.
I got a 4-pin installed just in case I decide to run bigger turbos and e85 down the road. That being said I agree with you and anyone thinking about buying an s55 car will absolutely love it with just a stage 1 flash safely.
I love how you challenge other theories and go against the gain to create bmw content.
Thank you! I feel things get blown out of proportion.
My second F82 i ran stage two for a little while before getting the hub done.
Mechanic was a close friend of mine and I saw the friction disk on stock hub and it was ripped in half and about to go any moment.
I’m in a pretty big s55 group here and I know people who do everything wrong possible to spin hub and nothing happens. Friend of mine on just capture bolt was running full e using kickdown often even on stock charge pipes and never had an issue and did over 10k miles in a year.
Lots of ppl do cbc and they are good some do nothing they are fine and some do hub. It would be great if there was just a straight answer. Just tuned my newer f82 on stock hub stage 2 and always worried it is gonna spin. Know tons of ppl who never had issues and sometimes ppl do. Just annoying situation.
I will say when my last f82 was running 590whp on e85 it was very nice knowing my hub literally cannot spin. If you are the anxious type like me then get it done or you can hedge your bets. Take for what it is worth
I try not to worry about it.
Most of the ones who spins just has to get the hub done and engine re timed. Now if people were replacing motors left and right. I’d be more concerned. They way I view crank hub is like taking cough medicine before you get sick.
Hey man I was wondering if I can ask you a few things about the f82 cuz I just got one and I’m trying to upgrade it you have ig?
love this video i 100% agree im currently in the market for an m4 not for the car to sit in the driveway/garage im gonna floor the heck out if lol
That’s what it’s built for!
I think the price of a s55 long block is a factor in all the worrying. I’m no crank hub expert, I actually build Audis. But I did work at a euro shop for a decade. And I’ve seen some middle class people get shattered dreams playing with high end beamers. Although it was mainly rod bearings back in the day.
Purchased my M3 F80 Competition 2018 model last month, only 1200 miles on it - I am not scared of the Crankhub issue, As long as you don't torture the car or go waaay above stock I think it'll be fine. I will do a stage 1 upgrade eventually and maybe take it on a few track-days but nothing more. Looking forward to summer here in Scandinavia :)
Any reason why you didn’t get the 2021 seems to be same price
@@lifewithjusto7777 it’s ugly
I have been running stage 1 for 40k miles, as long as I drive the car I redline it every time. If the problem comes let it be. If I am doing fbo e85 I might do the crank hub or track it really hard. Otherwise I won't worry about it. It's just a car!
I only personally know two other f82 owners in my area, one of them spun their CH. SCH is tuned stage 2 and happened after using anti lag. My F82 has close to 50K miles, stock, and no CH issues
Stock power shouldn’t be an issue at all. If you go way above the intended power, than sure, you may spin the hub, just as you may have other issues.
They hire M3-M4's out at the Nurburgring, they get hammered day in day out. No crank hub mod. 37 laps with an F1 driver behind the wheel, no crank hub mod. They are stock except for brakes and tyres. For sure If It was a high km car I would do it when it needed gaskets and the like, or if doing big power mods. If it was an issue then it would be a recall, regardless of cost.
I agree. There are way too many people beating the piss out of these cars than they are failures.
It's just like the LS7s and the Valves dropping issue. It was a less than 1% chance of failures that got overblown on the forums everywhere. Drive the car man. I've worked for BMW for 9 years(6 at a dealership and 3 at a private shop) and i've only personally seen 3 crank hub failures and they were ALL driver issues or age and mileage. 2 manual cars money shifted, and a DCT that was just 150k+ miles.
The LS7 issue was indeed overblown and some people like myself found out that the cure is worse than the disease on "fixed" LS7 heads. The main reason I worried about the valve drop is the sudden failure and severity of consequence. But for the S55, even in the very unlikely case of a spun CH, the chances are overwhelmingly high that there is no engine damage. For that reason I think the CH is something to address only if it fails. Otherwise, enjoy.
1%,? Half of them are having it..litterally half if not more now in late 2023
I’m stage 2 on my m4. Stock everything, only did the charge pipes and spark plugs.
I think you're right that this has been over-hyped, but it is a real issue. If you're lucky, you will get a check-engine light, but if you're unlucky, it could be much worse.
Nobody can say this isn't a problem unless you tune it or go over 600bhp or whatever.
This can happen on standard cars too.
The friction washers can separate and slip, which might not be fatal, and just throw the timing out for the valves a little, and can be repaired.
But in some cases, the friction washer can snap, which chews everything up, and the timing goes so far out it causes fatal problems.
Just like the E92 V8 bottom shells issue, this crank hub problem is not a case of if, more a case of when.
We had a customer do a full E85 tune dynod at 580 WHP on first revision. He spun his hun on his 2019 M4 in 3 days of running that tune. We fixed it and put him at 610 whp max effort.
I’m at 70k DCT 2016, daily driven, all stock. No issues other then a noisy idler pulley. Drive it hard, and drive it smart.
💯
How much i got cash
I got in a heated argument with some dudes about this issue. Statistically the crankhub failures only make up about 1-7% of all S55’s in the road. It’s pretty rare, I truly believe it was blown out of proportion by concerned drivers then dragged on by the aftermarket like you said.
1-7% sounds like a pretty big range lol
Every car seems to have a flaw like this, if you cant get past it then you will not have fun driving any car. If you're really worried about it just turn the dct down to the middle setting to reduce the shock of the shifts.
Great video and great car! Which do you like better? M3 or c63?
Both are good cars. If I had to pick though, the M3. The handling feels more precise. Overall the car is balanced well!
This video definitely is going to make me pull the trigger on this F82
Do it! Don’t let people scare you into thinking it’a going to blow with a crank hub job.
Hey ED, I currently have a F16 X6, I'm thinking about getting a M3 F80, Can u give me a heads up with some common F80 problems, Like for example with my x6 some common issues were valve cover gasket , PCV valve etc
Great video! After all this time, did you change your crank hub? Or still the stock one?
Regards from Portugal
No, I'm still on the stock crank hub.
@@eddiemcars great news my friend. Im now running stage 2, 530 hp and 726nm. Probably i will do the crank bolt capture just for that piece of mind i guess..
I do like 10.000 km/year and as you've said i drove it like a M should be driven. And yes, its blown out of proportion.
I'm stage 1 50k miles no issues. I'll do it before stage 2 after its old enough to smog
I thought so too. Now I'm in a really tough spot. I'm on my 2nd F82. I had a 2016 M4 Manual, Stage 2 + 93oct OTS MHD tune and downpipes. No problems after 18 months. Then I bought my 2019 M4 CS last February with 15k miles. Put the same tune on it at 25k miles. I always manually shift. NEVER kickdown. I really don't drive it really hard. Well a few weeks ago I did 2 back to back 40-150mph pulls messing around with a friends redeye Hellcat. Manual shifting. 2nd pull felt like premature heat soak. It didn't pull right. I let off the gas and bam I get the dreaded light from hell. Car still runs just in limp mode. So motor is ok. But I will tell anyone how much I wish I would have done the preventative fix. I thought it was a super rare thing too. I have 2 other friends. All 3 of us have similar mods. 2 of us have spun a hub. Well other spun hub guy was on E85. 41k miles and it spun. Shouldn't down play it so much. Something is gonna break? On the forums 95% of the time someone has serious engine failure it's the Crankhub. It's a lot more cars than you think. 6 people? I personally know 2. It's ridiculous how much BMW screwed this up. They really need to address it. Been a more than a few stock cars spin the hub. Don't worry about it like I didn't but if it spins cross your fingers the valves don't high five the pistons because you might have to set it on fire. Thankfully more often than not the motor is fine. Which is crazy for a interference motor.
The ones that had crank hub replaced what happened to their motors?
So I just bought a 2020 BMW M4 Comp and ran across this video. Noticed you made it about 1 year ago. Since then, have you had any issues or concerns regarding the Crank Hub? Have you added anymore modifications to your car?
I haven’t added any more modifications but I’m still not afraid to drive it the way I want to drive it. I’m at 60,000 miles and it’s still running strong.
The most intresting thing with this is that people think it has with horsepower and tuning to do. I am amazed how many people don’t understand how this works technically. People should take a look and see how the engine is designed and think about where the force and power goes and think about what in the oil and cam drive system creates more resistance just because you tune the car.
Peolpe need to learn how these engines work and stop believe in everything they read and what other people say.
I have driven mine everyday for about a year and a half with zero issues on stock hub. Granted i'm on a CS tune but with 85K on the dash I've gone through a DCT already before having any timing issues lol
I’ve had my F80 tuned for two years, I’ve tracked it 3 times with my most recent being on the CS tune. Still no issues!
Well I have a FBO stage 2 OTS e30 tune and I’ve been beating my car hard. No issues I’ve come across yet been driving on this setup for 10k miles. Maybe gods just on my side 🙏🏼😎
Well you only hear people that have issues or know someone who knows someone who spun the crank hub! It would interesting to see actual data of how many cars and what was happening when it did.
Thank you and thank you. Adding an excess of more power will cause that crank hub to possibly fail. Also excessively over Reving the car or missing a shift( manual trans only) can also contribute. BMW master tech bringing you conformation.
Just spun my crankhub today stock power downshift into second. Crankhub was always in the back of my mind. Now its in the forefront. Wish i got it done. kept putting it off
I dunno. I struggle with this. The problem here is the friction surface. It's basically sandpaper and won't last forever. High levels of torque--not necessarily tuned but let's say a redline shift at high altitude--can wear down that friction surface in the hub assembly itself. It's a matter of time. Not necessarily that your motor will go, but for sure your timing can get thrown off given the two gears that are on either side of the hub. The more torque you put through it, theoretically the worse it would get. Stage 1 and up, I'd replace it personally but it could presumably fail at stock conditions as well. It's just sort of a dumb design that baffles imagination. I recommend you actually try to get your hands on one to see how it works.
The factual data is minimal. That's why I’m on the drive it, enjoy it team. If it fails replace it and upgrade it.
Whilst I agree with using the car and kickdown....I didn't pay that much for my car not to use it...I don't think you fully understand the issue.
It is not the bolt coming loose or undoing in isolation that causes the problem. It is a friction washes that breaks down allowing movement, play and potentially then the bolt working loose. This is why the fix is a 📌 crankhub. People who just do a capture plate on it's own may as well just set 🔥 to their cash as it will not prevent the potential issue.
In the UK it costs about £1800 to get the crankhub fix and when my BMW Warranty is up I will give it serious consideration as, however unlikely it may be, it may just cause the timing to go out if you are lucky, if not then your whole engine could be toast.
If you keeping it stock, then keep it stock crank and beat it up, it’s meant for it, if you are going FBO and tune, do crank hub.
Pretty much! Or... Don't do crank up and take the gamble. When it spins, then you can upgrade anyway. I still haven't heard of any engines destroyed from crankhub failure.
I just want to say I appreciate the video. As hostile as some folks get over this “issue”, I honestly expected to get down to the comments, and see people lighting you up over your views on this.
I literally JUST purchased a 2016 M3 yesterday. It has 49k miles on it. I’ve been agonizing over this crank hub deal for the last 24 hours. I’ve literally been scared to wind this sucker out to redline as if it’s a ticking time bomb- and hey maybe it is, but it also may be perfectly fine, and I don’t want to not enjoy my “new to me” M3. I’ve had BMWs in the past, but never a full fat M car, and I can’t explain how excited I am to finally own this vehicle.
You video has made me feel a lot better about the whole thing. Not saying I agree or disagree with it being an “issue”, but regardless of how widespread it is, your point about enjoying the car is 100% spot on.
There is just no way after spending $50k on a car, I’m going to drop another $3k-5k on “fixing” something that may or may not ever be a problem. I think I will however pick up the Crank Bolt Capture plate, and do that install myself. It’s $100, so incredibly cheap relatively speaking, and it’s something I can install myself in an afternoon. Now if you hear the die-hards talk about it, they would say this isn’t the actual fix, and again maybe they are right, but I just refuse to drop the kind of money required to do the “full fix”. If I spin the damn thing, then I’ll pony up at that point to fix whatever it breaks, or replace the engine if necessary- until then I’m going to enjoy this car, and drive it like I stole it.
By the way- gorgeous color on your car. I wish I could have found a YMB F80. Mine is Tanzanite Blue, which is still really nice looking, but it doesn’t hit quite like that YMB. 🔥
Blue is my favorite color! Tanzanite, although more rare, was my second choice.
Yes I agree. It doesn’t have to be that serious with fixing something that isn’t broken. However, if adding a lot of power like stage 2 and e85. It would be something to think about.
Just purchased my F80 M3 as well just to be little one the safer side going stage 2 I just purchased a Crank Hub Capture Plate
@@AHMEDMUSA0130 just finished up that mod a couple of weeks ago. Pretty straightforward install. Hopefully it does it’s job!
This guy just said he won’t spend 3K to make sure your car engine is fully protected if you’re adding boost but willing to buy a new engine when it goes bad lmaoooooo
@@lifewithjusto7777 yaaaaasssss. Life at the limit. Fight me bro.
I was just like you and didnt believe the whole crank hub situation until I had the drivetrain code（130E20 and 130F20)on my m4, so yes its not as common as everyone says but its definitely real not some made up problem created by some mechanics trying to sell you the job and can happen to anyone at any time without any warning. so after my own experience I would definitely recommend to be safe than sorry.
I’m sorry to hear that! I still think a very very small percentage of it happening to. When it happens, you don’t lose your engine. You have to replace the hub which you would need to do anyway.
@@eddiemcars man i thought the same thing. 2 weeks ago spun mine too. It's not as rare as you think. Stock car is only way I wouldn't do it. If I had plenty of cash I'd still do it
You rockkk
I've heard it only becomes an issue if you do extensive power mods and drive hard most of the time. If you're closer to stock I've heard it isn't even an issue.
I completely agree. I have a 2018 BMW M3 Comp DCT with only 19,000 miles on it got it two months ago. Joined an F8X group chat and everyone calls you an idiot if you dont do your crank hub. BMW never even considered making a bulletin for this issue. Less than 1% had this issues and I bet majority of them had stuff done to the car or people cheaped out on maintenance.If you are going for 550+, bigger turbos, downpipe, tune, etc.. then do the crank hub . It was never a design flaw... It was enginerred for 444hp for the comp. Add more power=add more problems. Thank you for this video.
i’m not sure if i got the crankhub or not in my car but the way i treated it sure makes me think i do have one or this “stock” crankhub is a killer. (2015 f82 stage 2 tune)
Nope. I’m still on the original crank hub.
The only real way to know whether it's worth it or not is to get reliable data on how many have actually failed.
One big indicator would be the number of new engines fitted by BMW under warranty as a result of the crank hub. IMO, if enough were wereplaced, BMW would soon issue a recall as a new crank hub is a lot cheaper than a new engine.
I think the engine usually stays intact for the most part that’s why BMW hasn’t been involved.
I’ve seen a lot of stock spin their crankhub tho. But then I ask myself, pay say $3000 and get the crankhub done or rebuild the motor which is $10k+?
I haven’t seen anyone spin crank hub stock.
Most of it is hearsay for me so it’s hard to validate what’s real or if there’s a handful of people that spun the hub and the information is constantly being recirculated. I’m not denying the fact it exists, I don’t think it’s as severe as those make it out to be. Like I said if you plan to go to stage 2 and beyond it would be something to consider.
The crank hub issue doesn’t matter if you drive hard or drive like grandma. It doesn’t matter how many or how few miles you have on the car. It’s just luck of the draw. If it’s gonna happen then it will. If you want the piece of mind of not having to worry about it then suck it up and pay the couple grand to have a new one installed. It’s a crap shoot. You shouldn’t worry about it and there’s nothing you can do other than swapping out the old one.
Analyzing this issue from an engineering point of view, I don't see how higher power than stock can contribute to the failures. If you think about it, the acceleration force (likelihood of the crankhub friction surfaces between the sprockets slipping) on the crankhub is no different in 2nd gear on a 600hp car than 1st gear in a stock 400hp car. It's not under more load at higher gears like a clutch or other drivetrain components. So if you have a stock vehicle and you rip around in 1st or 2nd gears, it is no *harder* on the crankhub than a tuned vehicle ripping around in 2nd or 3rd gear.
Prove me wrong? Acceleration is not different.
The owner of the shop that does hundreds of crankhubs did a complete DIY crankhub replacement video and says the crankhubs spin because the bolt loosens over time (in some cases).
If the cause of the SCH is from the bolt loosening after a while, you can do the crank bolt capture plate to keep the bolt from loosening and keep the friction plates together. That's a $100 part and can be easily done in your driveway in an hour.
I agree the SCH issue is blown way out of proportion and doesn't make sense from a tuned engine perspective, lets say under 600hp.
A large portion of these cars have either come to the end of the warranty period or are heading towards it.
Is overlooking a crank hub install worth the potential outcome of having your engine rebuilt?
Most of the people who give a shit about the crank hub are probably buying it used with the intent to modify it.
True that cars are coming out of warranty. However is still It’s still unnecessary for the cars that plant to stay stock or stage 1. Just like I wouldn’t have a root canal or fillings 🦷 if I plan to eat a lot of candy 🍬.
I got my 2018 m4 last year and have done stage 1 so far. Before I knew about crankhub I drove it like I stole it. Kickdown, redline it didn’t matter. Once I askedd my tuner for stage 2 he kept saying I don’t recommend it because of crankhub…. I want to do downpipes fbo but it has me scared. I only have 21k miles on it
How's it going ?
This just popped up on my recommended the day after I got mine done🤣😭
If you’re planning to go beyond stage 1 I don’t think it’s a bad idea!
Just don't downshift hard. Crank hub will never spin on upshift due to the matching gear and engine speed.
in Portugal there is no record of failure crank hub, I have already tried to find out from BMW and from official representatives and no one had this problem
I talked to a few people who worked at BMW I heard something similar.
@@eddiemcars the point is that drilling holes in the crankshaft makes it unbalanced... so I don't know how far it won't create engine problems
Sorry to bring up an old video. I bought my 17' F80 comp back in 2020 with 21k miles and whenever I buy a performance car, especially a used one, the first things that go through my mind are "what are the common issues both catastrophic and non-catastrophic?" And "did the previous owner beat the crap out of it"(which honestly is hard to know). I've been reading about sch for over a year now on the forums (mostly old threads) I guess trying to decide how big of an issue this really is. I've come to the following conclusions:
#1 forum members represent a small percentage of ALL owners, so figure 20%(ballpark, may be much less). Out of that percentage, an even smaller percent have had sch and have posted about it. That tells me an even smaller percentage of owners overall have had the issue.
#2 The running theme I'VE seen on the forums is cars with sch are usually modified and seeing over 600whp... there ARE those who were stock or lightly modified that still had it happen but again, even smaller percentage than in #1.
#3 It still worries me BUT not to the point that I'm gonna do a full Crank Hub. At least not yet. From what I've read cbc no hub you can still "possibly" spin the hub(usually very high HP cars). Crank hub no capture cars have STILL spun the hub(again high HP). Crank hub and Capture so far, again from what I've read, no failures at all... so both solutions virtually eliminates the risk/problem. With that being said, my local shop has stated that they have multiple high hp cars with only a CBC running hard with no issues. My PERSONAL plan is to go mmmmmmaybe stage 2 (BM3 stg 2, Down pipes/exhaust, etc. No upgraded turbos) so for the peace of mind, I've settled on a capture. At least with that I'll have enough peace of mind that i can upgrade to where I want to be with no issues. Again just MY opinion. As you've stated, plan on going big HP? Over 600? Get the complete solution. Plan on staying close to stock or about 500? You don't necessarily HAVE to do a hub or capture, but I personally would do a capture. It's very inexpensive compared to the hub and will give you at least SOME peace of mind to drive the car as hard as you want.
I agree with you. It’s hard to get accurate data too
What was the owner doing exactly and are they being honest when the CH spun, what tires were they running and transmission. There are so many variables it’s hard to track it down
@@eddiemcars yes, and what's even more annoying, again from what I've read, a few people are reluctant to give that information... it's always "got sch...had a cbc and still spun" or "had a hub and still spun..." and they leave it at that. VERY very few have elaborated as far as mods, HP, what exactly they were doing. And even then, as you said, how many are truly being honest about how they were driving? For me, a few hundred bucks for a small peace of mind is worth it(crank bolt capture that is)... thanks for the vid btw
@@Sauce05SRT man seriously I just spun mine. Stage 2 93oct. Manual shifts. I'm kicking myself
@@rickdoyle4981 that is terrible news bro, did it have a cbc at least?
@@Sauce05SRT no cbc. This is my 2nd M4. Had a 16 manual with same mods. Love this CS. Honestly it sucks but it seems most people just need a retime and hub. My motor is fine. Found a shop to do it for $3600
I’m now at 49 thousand on my F83 M4 and I drive it the way I want, if it happens I can afford to pay to fix it
I have a different opinion on this and say it has nothing with horsepower to do. I have asked for a technical explanation from people who say it must be upgraded when you have so much horsepower but i still haven't got any real answer to that. Does anyone have a good explanation :)?
F8x is my next car but after knowing people personally who have spun them I am going to at least do a new crank bolt torqued to spec with a crank bolt capture from VTT all in around $125
The ones who spun their hub. Were they stock or tuned?
@@eddiemcars 1 bone stock, 1 stock with just tune, and 3 modded
I doubt it's gonna be 125 to change the bolt ...u have to make sure u don't loose timing when u take the old bolt out ....don't u need special tool to lock the crank in place and keep the cams timed?
@@bembus22 no it’s a crank bolt capture, it’s like a plate that locks the crank bolt in place. You don’t take the crank bolt out
@@bembus22 I can do it myself lol it’s a simple job tbh wouldn’t even charge someone over $200 to do it
for those of us who don't know what crank hub is... can you explain?
This will explain it and why it could fail.
www.ssrperformance.com/pages/do-not-let-this-happen-to-your-m3-m4-s55-crank-hub-failure-solution
Exhaust setup? sounds great.
Thanks! It’s completely stock!
@@eddiemcars no way!! I just picked up a f80 last week with stock exhaust, how do you do your mic setup? I have the DJI mic and some lav mics you gotta show me your style.
I have question about the f80 , if i installed a dp on it , does the check engine light will normally come on ?
If it’s catless, yes.
People who are heavily modified spin their crank hub left and right. I know tons of modded cars that have spun their crank hub. Stock cars however...I've never met a single person who's spun their crank hub on a stock motor.
Ironically everyone I know who has spun their crank hub has only needed a timing fix. I don't know a single person who has needed a new motor.
I’ve only read about one F8X that spun a crank up stock. It was posted on the forums but I can’t validate why or how because all the OP said was it was a brand new one and it spun sitting in the parking lot.
I just spun mine and only need retimed. Well I'm assuming because it still runs decent. Just in limp mode
There has been a handful of stock cars with under 10k miles. One was brand new yes
What are your legitimate thoughts on the e60 m5 v10's reliability stereotype?
I think a lot of it is stereotypes but the cost is expensive to maintain. I believe that can handle the power and abuse but I personally wouldn’t own one simply because of the cost of what’s is basically a “supercar” engine. The SMG pump is also a known failure point with those cars but how many exactly and from what I remember the cost of wasn’t astronomically high. Aside from the powertrain, everything else is typical BMW.
I test drove a few and even nearly purchased one that was in the 25k price range but I had fear and couldn’t pull the trigger.
@eddiemcars yeah, well said.
I had been seriously thinking about one for thr past year, but until recently, i hadnt fully interrogated everything i should need to know about it.
Obviously the rod bearings is probs the most well known fail point responsible for most peoples fear to buy.
But i recently learned that, as you say, the smg pump, smg gearbox in general, throttle actuators etc are all things that fail on this model moreso than others.
I wanted one so bad, but instead, in the next couple months ive decided to upgrade to a f10 m5 instead.
I currently have an e60 530i you see, and enjoyed the styling of it, hence the interest in the e60m5, (not to mention the power increase), but after a lot of thought, i think owning that car would be a singularity, with respect to my wallet doing nothing but feeding it.
Thanks for the reply!
I'd like to know the %percentage of how many crankhubs have spun... I've had my f80 m3 feel like the hub has spun afew times it just revved out like it was in neural🤷♂️
That isn’t what you would experience if the crank hub had spun. That sounds more like a clutch slipping. Is your car a manual or a DCT?
@@LetsGetTechy dct
@@mushy1983123 interesting. I haven’t heard about the DCT slipping in that manner unless it’s a massive amount of horsepower. Maybe tire spin or some traction control intervention. 🤔
@@LetsGetTechy I first thought it was dct slipping but I wasn't giving it full throttle and hasn't done it in a long time don't know what it could be no codes or anything came up
@@mushy1983123 maybe just a fluke with the transmission. Even only having my car for the first 24 hours, I’ve already noticed sometimes the DCT has a mind of its own- especially in drive with the “lowest performance” setting. Earlier today I gave it just a bit too much throttle getting on the interstate and it was jerking me back and forth like crazy. I know people who saw it were thinking it must have been my first time ever driving a manual vehicle, and I wanted to yell out the window “It’s not even a manual! I swear!” 😂😂😂
Im planning on just doing a stage 1 91acn tube bootmod3 with the gts transmisson flash. Do i really need to do the crank hub change ?
No you don’t. The stage 1 ACN is a mild tune.
@Eddie M Cars thanks for the response, is there any other mod you'd recommend I do since I'm considering a stage 1 tune ?
110k all stock f83 no crank hub issues
I think most people who have had this happen to their cars are likely 1. 2nd owner of the car purchased from someone who beat it to hell, or 2. You modded it and beat the crap out of it. This spun hub doesn’t happen on factory models that are cared for. BMW techs rarely if ever see this either.
I agree. I met a BMW tech and he’s never seen it and he was a F80 owner too
Bought my 2018 m4 with less than 20k miles… still did my crank hub. Yes the odds of it going bad are low but, to me, it simply isn’t worth the risk. It’s all preventative. I’d also recommend replacing that shitty plastic oil cooler guard as well… that thing ain’t protecting shit.
Personally, I don’t think there is a risk. I know the horror stories can scare people but I still think it’s over hyped.
@@eddiemcars Yea I can’t even lie, maybe I did get scared into it a little. But I just like the peace of mind of knowing it’s not something I necessarily have to worry about lol.
if it was truly an issue, BMW would recall it. Talked to my BMW service manager and he said he has never even seen an F8x spun ch happen.
U do need a hub spun mine yesterday on stage 1 (1500km) with 13000km on the clock
Wow. That’s unfortunate! What exactly happened when you spun?
@@eddiemcars hub spun shifting from 3rd in 2nd @5500rpm, pulled ignition misfired. Getting it towed to dealership ll let u know if warranty covers it but i dont think so. Hope my engine is fine and only the timing is off
@@AimSucker any update?
@@oneslowf80 got super lucky. fortunately nothing got damaged, the timing was 30 degrees off.
@@oneslowf80 dealership didnt pay up for it tho.
Its like 350 for capture plate ir 700 for solid hub not 1000s
Those were the prices at the time of the video when people were scared and there was huge demand. I’m not sure what they are now.
A CH capture isn’t worth the trouble of doing.
with my luck im not taking that 1% chance...
Hows your car now if u still have it? I'm full e85 on stock hub I just avoid hard down shifts
I still have it! It’s great!
@@eddiemcars do u avoid aggressive down shifts
Spend 3-4K for peace of mind or just pay 10k plus for rebuilt 😂😂😂😂. It’s a damn known issue very very well documented in forums. But okay run ur tune s55 without crankhub 😂
Yep. I use” kick down” every day! 😂
I’m sure one day my crank hub will spin…
Or the moon will turn green. Whichever happens first 🤷🏽♂️
I disagree! The issue exists on some cars yes! My mechanic has changed plenty most if not all DCT cars. Why the crap shoot. Just change the damn thing. The issue exists! 3k or 10k your choice. Ps I spun the crankhub mishifting my F30 335 by the way. Motor done.
That’s fine but your crankhub didn’t spin just by causally driving. It was caused by driver error (eg money shift).
I’m willing to be most people have done something similar and blame the car.
You need to do the reflector delete 😅
Lol. He live and another dimension.
Just because I watched the vid and many others before I bought my M3 at 55k miles.figured I’d come back and comment after putting 20k miles on it..fbo, bm3 stg2/xhp stg3 j daily it and do hoodrat shit all the time for the last 2 years digs and rolls no problems at all.
Is your car stock or tuned?
Tuned stage 1
You said 90% chsnce you're fine. That means 1 out of 10 is not fine.
1 out of 100 if you tune it beyond stage 1.
Most of the cars that break is a friend that knows a friend.
I can’t say it won’t ever happen but if the car is stock it’s a complete waste of money.
@@eddiemcars Yeah, stock I don't think it's gonna happen or even stage 1. I'm on my second straight 6 BMW, they make solid engine.
Eventually, it will spin. I used to preach the same thing and ran a tune for 2 years no issue until one day, when I was casually driving with my son, it span. Thought it couldn’t happen to me after preaching the same story but mine gave out
Well if it spins, then I’ll look into a upgrade for the hub!
cannot trust a guy with his ig handle on his car
Good thing I don’t have my IG handle on my car!
Don't listen to this guy. Get tour crankhub fixed
Going to stage 2 with E, yeah, but otherwise it’s waste of money
Sorry man, I think that you don’t know what you are talking about till it happens to you and you bend all your valves. Talking from experience :)
I haven't heard of any F8X’s that bent valves from the result of a crank hub. You would be the first. But I believe it's an unnecessary repair for stock or lightly modded cars. Some owners are afraid of using kick down or even go WOT at all.
@@eddiemcars bent valves are common with sch. many have had sch. so if ur doing anything stage 2 or higher, crankhub is a must have
Unless the s55 is a non interference engine there is no way it will not bend the valves. N54 is an interference engine and when I spun my hub I bent quite a few valves. S55 is a flawed crankhub design just like n54 and n55 for mild power and reliability. Pinning the hub is just the smartest thing to do when chasing big power since its a known issue. There is a pattern to hubs spinning I believe as well from what I've seen
I agree with your logic, it’s not as common as people make out; but Christ alive, please don’t take up a career in engineering, your explanations were horrendous. 😂
👍🏽
Lies don’t believe him. Spun my crankhub on a stage 1 tune
How did you spin it? Were you aggressively downshifting?
Stop worrying about it so bmw can sell their used cars..its a 25000 euro damage..and if you are lucky 6000..better with a c63 small electric issues 1000 timed..he ant sell it🤣🤣
