Took me a year to diagnose my driveshaft on my k1500. I did 2 alignments at 2 different shops, tire rebalancing and rotations and the driveshaft balance was something I was unaware of at the time and was a Hail Mary call. Wish I would have seen this years ago!
To diagnose by feel and sound is an art my friend. I hope some young people see this and are inspired because we need more mechanics going forward, or we will soon run out of this type of talent. Great job.
When I worked for Ford as a mechanic, my main job was as a NVH troubleshooter, yes, a lot of moving parts have different frequencies that you have to chase, great challenge to isolate.
Thanks Kenny! Didn't help me with my problem but a very educational video none the less. I'm 56 and still value learning things that can and will save me money. I'm not a mechanic but I'm still the one doing all the work on our cars thanks to guys like you sharing the knowledge on utube. THANKS!!
Rebuilding the rear end the right way,lost art! Tolerance on the money $ come back to shop$if not done right,the first time! Enjoyed step by step of analysis of problem!
I'm being chased by axles lately! I just rebuilt a Dana 45... yes 45 and that was my first time in this world - it was kinda ugly. The upper and lower axle arms on my 64 Bonneville I just had to re-bush with liquid poly. Seems, like you say, things come in waves. I once bought a 1967 MGB that had a terrible vibration and the guy was sick and tired of the whole car... believe that or not, and it was only a clump of mud on the driveshaft. After cleaning it was fine and I offered the car back to the guy and he laughed and said "you keep it man". I hope you get to rebuild this unit and I'd love to see your methods on this. I've watched many videos on axle rebuilds now and it seems everyone has slightly differing (Punny huh) methods and your ways are simple and work well every time. I'll be watching! Bobby
This video is the one that I needed to see because I have a 94 Chevy S10 that has a vibration and I just replaced the ujoints and the carrier bearing and I changed the plugs and wires this morning and it still has a vibration
I hope you get to do that rebuild too … I once bent a driveshaft once after I botched replacing a set of u-joints.. that shaft came loose and flailed around .. Bad vibrations..
Really interesting thanks. My landrover defender has a vibration issue. 4th to 5th gear 40 to 53 mph up an incline.Quick vibration felt a little through the steering wheel and front prop. However front prop is new, rear one is solid no play into diff both greased. Topped both diffs, swapped wheels around. Got it booked into the professionals.
Thanks for uploading this precious video on CZcams. My old merc w202 have a vibration problem that occurs between only between 80 90 km/h . Still trying to find out its source.
Get it to the speed it's vibrating then shift it into nutrail if the vibration goes away it's engine or transmission, if it is still vibrating it's tailshaft bushing towards driveshaft back and possibly rear end.
Wrenching with kenny very very good my friend. Ive been having vibrations in my dodge truck. Most helpfull, but more importantly hes very prof, genually has concern about problems, not like these other techs who are to into themselves to help you, so outstanding my friend. Im not evdn a car buff, but i subcribed because i will need i say need you agian someday thank you and to you and yours be well sir
I have a 2000 f 250 4x4 i have a vibration starting at 53 mph to 58 mph then smooths out!! Not bad just annoying. I put new u joints in, shocks , wheels balance. I put in neutral at those speeds and no difference. Not getting worse samefor 2 year's. I give. Lol. Good video. Thx.
I had that same stop driveshaft thud coming to a stop in my uncle's 92 Silverado. I fixed it easy, some one flip the drive shaft connection to the rear end and it was off balance just flip it 180°
That is exactly what my ford f150 is doing and I kinda thought it was a motor mount but I haven't inspected it yet because I haven't had the chance but now I'm wondering if it could be the issue with the drive shaft that u were talking about
Replace bearing on the pinion then check your clearance in your ring gear and pinion should be fine unless you have another unit laying around to exchange it with
I had my rear drive shaft weight pop loose and start hitting my fuel tank gage on a 17 Tundra with 120 on the clock while towing a 4K lb trailer. No vibration though. Dealer pushed the weights back and said I was good for a bit, but recommend a new drive shaft. I then heard a pop driving it 40 miles later and the weights started hitting the fuel tank cage again. I’m the original owner and rarely off road my truck. What might cause this? Dealer said U joint was fine. Good video. Thanks.
I had a 2018 chevy 2500 last week. shook so badly it made the steering wheel vibrate too between 30 - 35 mph. it was the drive shaft U joint. just a caution about drive train not shaking the steering,
Rebel the more cutter drive shaft I'm 80 years old Well I was 20 We would put them in the car Drive shaft Take a soapstone and build a bracket and move it over till it just touches the drive shaft wherever it touched well the weight on the other side Move it over 1-in doing it again two three times sometimes four times to get a line of soapstone all the way around the drive shaft
So, if the vibration feels like a “driveshaft” vibration, there’s likely something out of balance in the driveline. And if it feels like a wheel bearing, it’s possibly a defective bearing in close proximity to one of the wheels. And if the vibration is in the front end of the vehicle, it’s likely an issue near the front end of the vehicle. Thank you.
Helical cut hypoid gears. I’m dealing with my F150 having a driveline vibration. Transfer case and driveshaft replacement on the horizon. Those two piece driveshafts have slip bump issues.
Yes, but you will be uncomfortable. Hi, It's Mrs Wrenching! If you get stuck, go on the Facebook group Wrenching with Kenny (answer all the questions) put the year, make & model of your vehicle in your post. Be sure to include what is happening with your vehicle & what you have done to fix it so far. There are a lot of techs that may be able to help. The link is toward the bottom of the newer videos. Keep wrenching!
Really need some help here ... Would a weak (not as stout as the original) driveshaft cause a 2006 Pontiac Torrent AWD to vibrate under hard acceleration or while turning left or right. BTW ... 1. The two-piece driveshaft and carrier bearing are less than two years old. 2. Same applies to Motor and Transmission Mounts, plus Bushings, Control Arms, Ball Joints, etc. 3. In short, all items are fairly new except the tires that are five years old (General RT-43s).
Had this issue on my bmw 1 series the pinion bearing had gone ended up just buying another diff which was a rare 4 bolt one which they are expensive cheapest one on eBay was £500 luckily I managed to find one for £180
The Ford two piece driveshaft is notorious for having the slip bump issue. There’s no real way to fix it, you can take it apart and grease it, but it’s a short term fix. The bad part is that it shoves into the front shaft and carrier bearing which destroys it. It’s made to be non serviceable, therefore requires a replacement driveshaft to be installed. Very expensive from Ford. My driveshaft ruined both the carrier bearing and the transfer case. Truck had a horrible vibration that didn’t go away even after the driveshaft was replaced with an aftermarket one. The limited slip clutches went bad, and it had an IWE fail too. I spent about 10k getting all that fixed in addition to the lower ball joints, and new transmission lines installed before they snapped off unexpectedly as they do with the 6R80 transmission that will be decimated by that happening. I love my truck though, and figured fixing it would be way cheaper than buying a new one that won’t be built any better.
The helical cut gears when in good shape are made to be smooth and quiet , but,! IF they loose the bearing and race dew to an oil leak will act exactly what you just showed us , a lot of shops , like me won't touch it but, if you know what you are doing , have AT it make a good profit and be someone's hero for the week because not many Men still know how to do it right , I'll bet you can because the way you explain the concern of the CUSTOMER ,,,, just don't do like I did 40 years ago ( forgot to put my ninety /W ) BACK IN THE HOG HEAD GLAD IT WAS MY TRUCK 🥺
I guess I’ll crawl back under this Camaro when I get off work. I parked it in the garage because I couldn’t isolate where this humming grinding noise is coming from. Sounds like it comes from the right rear wheel. But it only does it while accelerating and I feel it in the shifter
Driving my Yukon i felt a vibration in the floor. I was the only one who could feel it. The distributor was broken at the ear with the threads to attach the cap. Epoxy.
I feel mine at 45 mph in my seat vibrations. Had tires balanced and even put new drive shaft in. I'm thinking might be front drive shaft. Probably tomorrow will pull that shaft out and drive it and see if it does it.
South Main Auto just had one where the pinion bearings went after losing most of the oil but the rest was still okay. Look for pinion bearing fro hell.
Will the vibration throw a code? My check engine light came on at the same instant the vibration started. I can’t pinpoint the shaking, my rpm’s are smooth, but I have a weird shaking, almost like a motor mount. Unfortunately the obd port isn’t working, so I can’t scan for codes. 05 f150 2wd Thank you
perhaps a wheel/tire issue. bent rim, bad belts in tire, badly balanced or lost weights from last balancing job. I would think if you have a shop with reasonable balancing prices start there, some tire shops warranties give free balance checks if you bought tires there and had them mounted there.
@@WrenchingWithKenny I checked U joints they seem flawless , it is lifted with an unknown hight from a previous owner. Has 4" body spacers too in combination with the lift kit. My trans is nearly perfectly horizontal but my pinion angle is nearly diagonal so I wonder if I'm getting a weird spinning shaft at certain speeds.
Hello I drive a Honda 2004 crv, when I’m driving 60-80kph and it starts shaking when I stay at a certain speed without that limit for more then a few seconds and stops when I slow down or accelerate and I put a camera underneath and I can’t seem to find out why
@@WrenchingWithKenny Customer refused repair ...run it till it runs no-more! Be well Ken Thanks!....I guess it all goes back to the axel seal leaking for a LONG time!

Completely agree!
The new generation will wamt to plug it in like they were taught. We will need real mechanics!
A year passed I think we ran out lol

Love this channel man.
You're The man, professor!!!
Thanks for the vibration tutorial!
Thank you. Excellent talk about drive line problems. I appreciate the time you took to put this together.
Good stuff, a lot great info on what to look for and feel. In certain noises for driveline, thanks for posting
Great explanation of drivetrain symptoms. Thanks!
This man is awesome. Just found him. Glad I did.
You helped me so much with my Silverado Lt thanks

I find these interesting, it would be a fun one to follow along. Even a little autopsy would help, if the whole axle is replaced.
Yea. I'd certainly disassemble it if we swap out the whole rear

What about if you feel it on both steering wheel and seat? I have a 2000 ford f150 5.4l xlt 4 wheel drive

South Main Auto just had one where the pinion bearings went after losing most of the oil but the rest was still okay. Look for pinion bearing fro hell.
I will check it out. I love SMA
is the vibration present in the steering wheel?
Siezed up ujoint or slide shaft
what makes the video appear that you are in a right hand drive car sometimes and sometimes left hand drive
What is it when it starts to vibrate when you get over 60mph
Helical is the word I believe or beach boys good vibrations.
I could swear I saw a crack in that differential housing in one of the shots. At minute 11:14 to 22.
U-joint! Then again I ran into a yoke bearing doing something like this.

I have replaced my entire suspension and new tires I still feel a slight vibration in seat and floor . I’m puzzled.
What about a vibration you can feel through the car at a higher speed say between 70-80 mostly through the body it seems like.
perhaps a wheel/tire issue. bent rim, bad belts in tire, badly balanced or lost weights from last balancing job.
I would think if you have a shop with reasonable balancing prices start there, some tire shops warranties give free balance checks if you bought tires there and had them mounted there.
My 1990 manual trans bronco vibrates at like 64-75 down hill mountain freeways. Not uphill or flat
Check universal joints because of the way the load is applied. Let me know. Os it a 2 wd or 4wd. Is it lifted?
@@WrenchingWithKenny I checked U joints they seem flawless , it is lifted with an unknown hight from a previous owner. Has 4" body spacers too in combination with the lift kit.

He better be glad it's not a 9 3/4 because u cannot get the pinnion bearing I had hell finding one for mine
Not a pinion bearing ?
