- This is a 1993 z71 with a 5.7l 350. the flex plate is cracked completely around the bolts. you can hear when its under a load the clacking noise stops. maybe this will help someone diagnose there issue.
Hey man. It is 2021 and your video saved me the trouble. Thank you so much from the other side of the world. 👏👏
Your welcome
It’s 2023 and you’re still helping people with this video. This sounds EXACTLY like my 84 Impala..
Glad to help
never thought the video of my old hunting truck would hit so many views. thanks everyone
If I send you a video of mine are you able to tell me if it was the same sound while the vehicle is idling?
@@frederickjuneau7874 i can give it a shot
A lot of people wanna hope that whatever noise they are hearing is something besides rod knock lol. Including myself
@@creator4413 haha this is a very true statement

I can confirm this is the noise….I rode around with mine broke for a month rattling around until it blew up at 80mph…..Torque converter is toast
What kind of vehicle do you have? My 05 started making noise a week ago and come to find out was a little low on oil, thought it was a rod knock but went about 4k rpm going to highway speed and lost all power and towed home. Got plate and torque converter, hoping it's just the plate 🤞🤞
@@Ni_ghtmare 06 Trailblazer it would only rattle on Start up and Shut off which is why i assumed it wasn’t too major i also had no shifting problems even leading up to the event, Converter was toast cause of metal chunks tearing it up :(
@@DavidsLifeYT yeah, I have an 05 ram 1500 5.7 hemi, heard rattling but needed to do some work and had no choice but to drive it and figure it out after. Was coming home, passed the bridge by my house like 3/4 of a mile away and heard a snap and lost all power. Bought the flex plate and torque converter, thinking since I dropped the money I'll just go ahead and put them both in (265k miles and never taken trans off) didn't have any shifting issues either before it started happening.
Would take it's time going in reverse but other than that it drove perfectly fine. Will update tomorrow when I do it just to keep you in the loop 😂😂
@@Ni_ghtmarehow it go
You should make more of these what it sounds like videos. Its what ive been looking for
This is EXACTLY how my shit sounds... MAN you just saved me.
Thanks for sharing this video. I knew immediately my son’s flex plate was cracked when I heard the sound. I rebuilt the transmission myself. No bad flex plate then 2 years ago lol. But trying to explain it to my wife was hard lol. How do you know lol. She got a blank stare lol. You confirmed my sound diagnosis. Awesome video.
@@jamiegoodson950 glad I could help. The truck in the video I bought for cheap because of a "rod knock" but as soon as I heard it I knew what it was.
2024 and you're videos the reason my 94 chrysler lebaron is gonna get back on the road
It did turn out to be the flexplate. it was cracked all the way around the bolts
Hi did the issue happen after the clutch was replaced or it happen just like that . Pls guide . Having same issue just 1 month after replacing the clutch and flywheel .
We
Can that affect the transmission after a while
@@driverman9528 thanks man yeah i was thinking it was my battery but im not sure because it makes that noise and it takes a couple of turns to turn on then when i step on the gas i hear like a plate hitting something thanks alot for the feed back
@@joseramirez9932 not likely to affect the transmission but some of the old heavy flywheels would sometimes shatter and if that happens its about like having a grenade between the engine and transmission.
This happened to me last night an hour away from home had to limp it back this video saved me I thought it was a rod knock but my vehicle is making the same noise
Well this makes me feel much better.
Mine does the opposite. It sounds like a rod knock under load. Great video
My 2004 Lincoln Navigator sounds like rod knock at 40mph to 60 mph it will stop then come back and go away a day but I hear a grind at start up sence I bought the suv
Looks like I'm getting a new one lmao. Thank you sir!
Anytime
Youre a life saver my suburban makes the exact same noise
Lost OD? Or it falls out of OD? Mine too,
Thank you. You save me from buying a new clutch before i started the work.
You must be a troll.
Nunya Notta a flywheel can get cracked around the bolts and sound the same on a manual car.
2024 and this helped diagnose my truck
Man! You just solved a lot of questions!
Yeah my 95 Dodge van started doing the same thing did you know thanks I won't get ripped off by a shop
2024 and still helping ❤
Did you ever determine what broke the flexplate in the first place? . . Besides the common reasons (that we always hear about). Mine was breaking around the crankshaft bolts due to improper alignment of starter to ring gear. If there's the slightest slant, it will stress the flexplate over time, and will crack around the center. Yet there's no damage to the ring gear, because it will still mesh just fine.
It was broken before i bought it. I just replaced it and it hasnt hapened again
My 97 f150 started doing it 6 months after I put a new motor in it. Thought it was rod bearings found out it wasn't but changed them out anyways. It remained me of a lose flex plater or torque converter being loose not all checked out. I came to the conclusion it was either the flex plate or torque converter. Both can make the noise. So when I drop the transmission I will just replace both at the same time and be done.
I had my transmission rebuild, 1700 bucks. 700r4 in a obs k2500. 4 months maybe it is doing exactly that. I took it to them hoping it was that. They called me next day saying they think it's the motor and want me to come listen to it.......I know what it sounds like there Bob the builder, I need you to tell me yes or no is not the trans. Well they are convinced it's the motor but every gear head I'm friends with are telling me definitely the torque converter or flex plate. We'll see
Did u fixed ???Hope u did not buy a new engine i have the same noise and i spend lots of money on a new supercharged engine and new tranmmission noise not gone they change the torqueconverter and use same flex plate and same thing now is going back to the dealership to get new flex plate hope it fix the problem
Great 👍
1.000 questions
One Answer.
After replacing my timing chain for no reason, i'm literally 2 billion percent sure it's this. It's making that chain dragging noise but it's obviously not the timing chain lol.
It’s like someone dropped bolts in you’re engine but it’s not even in you’re engine 😅
Bruh you just found the mystery noise going on with my 2012 manual
you and your old video saving all these lives haha your such a hero,haha kidding bro,i have a 95 z71 ive had it for 23 yrs now and ive replaced the trans in it like 3 or 4 times not sure why,its a 4 wheel drive im not racing in it you know,but yea i put it in gear and it sounds like a metal coffee can with some nails in it shaking it up and down,i put it in park and it stops omg im so tired of working on stuff,this was the FIRST video i watched and boom looks like its this,i removed the bottom shield like you did hoping there was a rock or something but didnt see anything and i knew it was a crack,thats why i typed in cracked flexplate,damn the man,well like everyone else here thanks for confirming it for me.later
Haha yes sir glad to help. The truck in the video is a z71 and I bought it for 500 bucks because they said it needed an engine. After hearing it run I knew it was a flex plate. After you hear it once you can identify it pretty easy. Take care
heaven send, 2009 tucson made that sound for 3years. after starting flywheel grips the starter gear causing both to turn and burns the starter up. this gives me the right direction to do repairs!!!!!
My 350z does the same thing thank you!!!’ Thought I had a bad transmission 😅
mine makes that too.. it cause 3 starter to break into pieces.... .. i have no idea how fly wheel can get very hot, horny, dusty, windy, and cranky... thankss for loading up video...
VANflawless flawlessNIXION Why would you buy 3 starter motors and not kust get the flywheel fixed, them bits have entetered your gearbox or flywheel and will have done a lot more each time.
thanks definitely helped pinpointing the problem i jave with my 2000 BMW 323i. . i thought something was loose or my support plates where loose again ... is it safe to drive with this problem ?
15 seconds of life just listening him flipping the keys
Velizar Milutinovic yea what a jackass
@@TheBigstew5508 hahaha
Dude! This shit now is the exact same noise my truck makes. 2004 GMC sierra. Baby last me for a long time. 305K miles and running. Only bad thing is this loud sound. It's embarrassing dring home after a days work with this clunking sound.
My Herpes Itch my problem was a crack in the flexplate. no big deal to fix
I just have to say thank you so much you are a fucking saint. Same exact thing just happened to me and I’ve been freaking out, didn’t know what the hell was going on.
Man my crown vic sound just like that
Hello, hope you're well today. I'm a producer with Time Inc. and I'm reaching out to see if I could use this sound for a project we're working on. Could you please reply to this comment if you're interested and we can set up a way to discuss further? Thanks!
Adam Keller you may use it as yoh please
For so long I drove it like this and then yesterday I started it, after the noise quited itself and it finally started sounding like a rod knock, dropping the trans rn and replacing it currently lol
How long exactly did you drive like that ?
Thankyou for your video
Was the whole clip your flexpate or your exhaust too I have a similar sound right under my car almost sound like its coming thru the exhaust
I hear that noise ok my k5 when down shifting from 4th and 3rd gear?
Was that noise change from shifting in and out of drive?
Yes
I think the first noise was the flex plate and the second one was his exhaust. Maybe a leak or an after market muffler.
Excellent
Won't you hear the same noise if it is partially engaged in 4wheel drive, check your 4wheel drive shifter to be sure it's in neutral...
nope...must be the starter...thank God!!
Went from helicopter to tracker
I went through the same mess with my Corvette it was literally whittling starter gear Bendixs away problem was completely solved after changing the flexplate
hey can u help me i got a 5.7 hemi on a dodge Durango , how can i get a look at the starter on it , i couldnt find it looking today , im having issues with it need to see what its doing when the key is being turned it just makes a click noise.
many many tahnks, i have the exactly smae issue , only twice i heared that sound, sou its time to change this part
Nice video. Perfect
My town country van has that strange noise which is coming when ever I turn on the car. If I also turn the AC on the noise gets more. However when I Accelerate and put my foot on the gas and drive. the noise is stops and then when ever I took my foot of the gas and slows down or making turn the noise coming back.
Mines doing the same what was the problem
Sounds like any other Chevy
😄
Did it knock at higher rpms? I have a similar issue but only at very low idle. When into throttle it stops.
When under load or under climbing rpm the Knock would stop
A bad flex plate can also damage starter
Does it go into gear? Does it engage into gear?
Would this cause the truck to stop and turn off ???? Pls help.
A family member Trailblazer sounds like that and it happened when she turned coming out of her doctor but there's no exhaust smoke from the exhaust
2012 honda civic.. about 200,000 miles.. had teeth missing on flex plate..fml.. 900 bucks lol
Does it ever stall when put into gear?
Does it have dual mass flywheel?
My buddy's truck had the same problem... he went in for a rear main seal leak and the jackass mechanic ran the bolts down with an impact so tight it cracked the flex plate... I installed a new flex plate and torqued to spec, no problem since.... beware the quick lube places
Brendan Rapa quick lube places are garbage, i try to do as much as i can on my own to prevent stuff like that
I woke up to this noise on my 2012 Tahoe and really leaning towards , starter staying out, or some type of flex plate issue????how long can I drive this? Wat can happening I do?
What all did the bad flex plate affect cause I’m having issues with my flex plate on my 2010 Camaro ss
I was driving my dads Passat got engine failure warning we had it for awhile the sound and jumping got worse eventually it was only going 70 with the foot down not changing gears properly
1978 cutlass knocks at idle put it in gear no knocking even when u rev the engine in gear still no knocking put it back in park knocking comes back flex wheel ?
Sounds like it could be a bolt on the torque convertor has come loose. If it has then every time it comes to the top of the bell housing it will make contact. The load put on it while in gear may move it just enough to prevent this contact. If that is not it i would suspect a cracked flex plate.
That’s what I’m think I can’t see any cracks but the best way to really see is to take it out
How do you know it is thr flywheel, and not the starter?
Zach Heffernan there was no visible damage to the starter. It also stops when under a load thats why it stops the clacking twice in the video because i pit it in gear
You know when I fire up my 86 I hear some weird rattling think it may be flywheel but only when it starts and never again any ideas
Could be a crack on the flexplate. Listen to exactly where its coming from and go from there
It could be the starter not disengaged
My car is making a rattling noise but it's like yours right when i start it it makes the noise but a few min later it goes away. Did u ever figure it out?
I have a 2014 ford explorer fly which is making the same noise when accelerating after that feels good but when going to slow down or accelerating again I hear it again like metal rubbing metal
Are if there are metal shavings in the been housing. If there are then check starter clearance.
Going through this rn 😂
Looks misaligned. Idk if it just my eyes
I have problems with mine but it’s the Teeth on the wheel.. fixing the weekend
How much did that run you to fix the flywheel teeth
Torque converter fans are coming apart. Replace the torque converter and flywheel.
Dylon Phelps wrong
Dylon Phelps I agree I am going to replace flywheel and converter on my nephew's 99 Suburban this weekend I think that is a good deal converter 40 bucks extra and hopefully they'll take care of it
Mine is making the exact same noise. I have a 1990 RS 305, when I started it does the same thing but after it starts to idle evenly it stops
Was it the flexplate? Im having the same noise on 2002 impala but goes away when the engine geats up to operating temp
Mine does that when hitting the gas
I have 2007 Yukon Denali make the sound like a bell right by the flywheel almost like the video.
Can we keep driving like that for a long?
I would fix it as soon as possible. Driving on it isnt real good for the engine or transmission. But that being said you could probably get by for a while. I drove the truck in the video for a year before i eventually fixed it
Exact noise I'm hearing in my truck
before removing the flex plate check the bolts around it to make sure one hasn't come loose creating the noise
i took my ford e250 into the transmission shop who had previously rebuilt my transmission and they looked for a crack in the flywheel and couldn't find anything. All they did was remove the starter and a cover and put a scope up. They said that they don't know where the knocking noise is coming from because the flywheel looked fine. Is it possible to find a cracked flexplate with their scope method? I hope they just missed that part lol. thanks!
Mind was bad enough where is was obvious. You may unbolt the torque converer and slide it back to get a better look
hows it going man yea i know its a old video haha hey bro my 95 z71 that ive had for 25 yrs now it was making that noise so i just got aroundto replacing it,i took the old one out and there was not a single crack in it dude,so i replaced it,cranked it up sounded fine well then when i put it in gear and was backing it up on this little hill where i park it today it started doing it again,so i got someone to sit inside and put it in gear while foot on the brakes and i crawled under to listen and then it just quit,so i got in it and drove back and fourth up and down the hill putting some stress on it and it hasnt done it again,not sure if it will or not,but while we were hearing it while in drive it just stopped all of a sudden,im super sore and tired from doing this crap do you have any idea why or what it could be,the old one wasnt cracked,was yours,i saw a couple marks up inside the bell housing where it looks like something hit it in two spots but i dont know if that was anything,any help or ideas bro.god im beat,i left my transfer case attached and just slid the trans back enough to get in there to change it.thanks
Couple things come to mind. Could be the starter not properly shimmed to where when the flex plate flexs it contacts the starter. That sounds like the most likely scenario to me. A differential that is low on gear oil could also make a similar sound. If you were going up the hill in reverse those sound like the most likely culprits because reverse is lower geared plus the strain of going up hill. Try to replicate it by putting in reverse, mashing the brakes (to simulate load) then give it gas. See if makes the noise again. If it does then more than likely the starter needs shims
BTW this is my video. I'm just in a separate account rn
@@TheBigstew5508 thanks man yea i saw another video and it was the starter on his truck,come to think of it,its the original starter haha so its oh wow 29 years old haha,i installed the engine in 2006 its a 350 HO with a slight cam,i was thinking about pulling the bottom cover off and looking at the new flex plate to see if there were any wear marks.damn cant believe i did all that work for nothing,oh well thanks man take care
@onewheelup happens to all of us. If it makes you feel better I've seen trucks sell that had a "rod knock" that turned out to be a loose torque convertor bolt hitting the bell housing.
@@TheBigstew5508 yea i know man,you know you have two types of mechanics,one finds the problem and fixes just that,the other throws parts at it until he finds the problems and thats how i feel,i just dont know anyone to ask,i dont have a single friend anymore,you know i did a complete every nut and bolt ls 6.0 with cam and centrifical super charger in my blazer all by myself,geez talk about a lot of work and trial and error but anyways hopefully its just the starter and nothing serious.thanks for helping me out man it means a lot.like i said ive had the truck for 24 yrs now,while under neath i see ii need to power wash then do por 15 cause theres lots of rust.uhhh it never ends.later friend
My Audi A6 makes that sound when I start up and when I slow down
My A3 sounds like this now too.
was that noise going away wjen you put ot in neutral?
it went away when put in gear
+TheBigstew5508 like clutch pushed in and no sound? was it also your bendex gear on starter not adjested right ?
+Iworkupnorth.com it was the flexplate. it was cracked
Nooe that aint it. My starter is getting stuck on and it makes that eeeekkkk sound like it would starting a running car but mine isn't running. I was told the teeth isnt engaging with the starter..help!!!
if its a chevy there notorious for the flywheel cracking
My 2.3 liter mustang makes almost a similar noise. I got to replace the rear seal in it anyhow and have the transmission rebuilt.
Can you hear it at high rpm ? Like super loud
No it goes away under a load. If ut gets louder with rpms then may be abrod knock
FamilyMatters2015 it’s sound exactly like this , rodknock is loud , it sound more like aggressive grinding at high rpm
@@alonzo5.040 you should have an inspection port on the bell housing. Best thing to do would be to run a bore scope in that port and take a good look at the flywheel/flexplate. Ive also seen the torque converter bolts come loose and will tap the bellhousing every time they spin around. May check that as well. Easy to do
FamilyMatters2015 thanks man appreciate it
My f150 97 do the same noise I live in Oregon but I need to drive to California you think I can make that trip could you can help to know it's like 1000 miles
I wouldn't chance it. If the flex plate is cracked there is a chance of it coming apart. I've heard of people getting seriously injured by flex plates exploding under high torque in older vehicles. It can come though the floorboard if it has enough force behind it.
My 86 Monte Carlo SS, does the same shit...thought it was a bearing, but when car warms up it's fine, for the whole day, just on initial startup after sitting in the garage. Replaced flywheel and starter, when left stranded...Now, won't start(after 6 months of use), just that annoying GM "zing". I hope it's the starter, and not because the lazy asshole mechanic didn't torque my new flywheel to spec.
What's the cost to fix this usually?
i just priced out a flex plate replace based on hours, my shop says min $700, its a big job, taking the trany lose and moving it backward
Hi question what kin of car is it.?
1993 chevy z71
My truck was making same sound every time I start it but only in the beginning not when I drive it, I thought was a piston but I think is same issue, 3 days ago I start it sound was gone but doesn't engage shift any gear, what could it be¡¡
It would be worth looking into the flexplate. If it sheers off just right it may not be connecting to the torque convertor. Pull pff the inspection plate and see if has wiggle. May check to see that the bolts are still connected from the flex plate to the torque convertor too
What kind of engine is in there
Was just an old 2 bolt main 5.7
I HEAR A ZIP NOISE WHEN I START THE CAR SOMETIMES. ANY IDEA ON WHAT IT COULD BE?
WIZZLESODOPE YALL KNOW probably the starter
Starter
Starter not aligned properly
I have an '87 Ford Tempo , it squeaks & squals really bad have sprayed the flywheel only for the noise to return.. HELP!!!any suggestions???
Frederick Kidd if it is coming from where the flywheel is then it may be the torque converter. Check your transmission fluid for material
FamilyMatters2015 nothing in trans fluid
Probably the torque converter
Too close. Drive gear remains engaged.
Mines nit doing that. My ford taurus is chirping from the transmission area any thoughts anyone??
My flex plate is cracked as well. Only to find out the torque converter is actually stuck to the engine as well. Mechanic is on it, but he said if they can't get it off I have to get a new engine..... They've been trying to get it off for about 4 hrs. Next step is cutting the torque converter like a pie and putting some heat to the center. Please pray for me lol engine is clean as can be too. It's going to suck having to get a new engine when there's nothing wrong with mine..
Suh Dude good luck bud. Put a little heat on it and have at it.
FamilyMatters2015 thanks man
Suh Dude what happened??? Results?
Shoot, I’d find a way to get it off.. even if I had to pull the whole thing engine and all and use a blowtorch and a friggin jack hammer! Lol
manual or automatic transmission?
Automatic.
the turbine bolt are lossing
Some people are saying i should check my flex plate for the noises my truck is having Could you all watch the video i have on my channel and tell me your opinions
How to make Minatory
When this happens, does it come on all of a sudden or does it get worse and worse? Is it hard to fix? Thanks!
Could come on quick or could take time. What is happening is the flex plate is cracking. In this case it was pretty severe crack all the way around the crank bolts. To fix you will have to buy some long bolts to place where the transmission mounts to the engine. 2 or 3 bolts about 6" long should work. Remove all the bolts for the bell house and torque converter. Remove the cross member and drop the drive shaft. I like to use a ratchet strap to help support the transmission. Install the longer bolts carefully and slide back the transmission giving you enough room to reach the crank bolts. Remove and replace the flex plate then re assemble. Be sure to use lock tite on the crank and torque converter bolts
You could also drop the transmission but I prefer the long bolt method
@@TheBigstew5508 awesome! Thanks much!!
Could a flexplate make this noise only and only after 40 miles an hour from a dead stop to 40 miles an hour there is no noise but after 40 miles an hour there is a noise just like your video 🤔
That's just how minds sounded but I get it fix
Jay Stewart how did u fix it?
Jay Stewart was it the flywheel
Fly wheel sounds fine, and I would know
USMC FT BLASTER it shure didnt look fine when it was pulled. Was almost in 2 pieces. Cracked all the way around where it bolts to the crank
FamilyMatters2015 well than that's one quiet fly wheel, mine would make a loud clacking sound occasionally and then on prom night my car broke down and we found out the fly wheel is basically in pieces, last I looked at it it was cracked so bad it wasn't even, it had an upper layer and a lower layer from where the crack was
USMC FT BLASTER yea mine was in a couple pieces
Think u need some more keys
I think we all have the problem of too many keys
