Chevy GMC Truck Rear Differential Bearing

- This video includes general tips for replacement of rear differential bearings and components in Chevrolet and GMC trucks. This is not a complete unit repair video but simply highlights certain aspects of repairs related to this drivetrain component. This vehicle has a failure of the inner pinion bearing resulting in a jet engine type roar while driving. The failed bearing produced metal particles which warranted replacement of all differential bearings. Watch this video for more information. Thanks!
An effective field repair (or back yard) method of checking lash can be performed by installing rung & pinion visually close, then feed a strip of paper between the ring & pinion while rotating them. The paper will be marked by the oil on the gears, and the gear patterns will be clearly visible when lash is close.
If the paper jams up & impairs turning of gears, lash is too tight.
If there is not a clear inprint of gear teeth on both sides of paper and paper does not come out creased & folded, lash is too loose.
When the pattern marking is well defined and the gears starts creasing & just start slicing the paper, lash is close enough for G80 work, and you can go down the without damaging the ring & pinion.
Always replace old pinion bearing with the same brand. For example, Timken with Timken.
I owe you a good steak. I enjoy your vids. You have a relaxed tone and approach that helps remove some of the anxiousness in taking on some of these repairs. Thanks again. (The vid of yours that really helped me was on a Subaru. This one is helping with my 1994 Suburban - sometimes, you just need an old truck. Thanks again!
Tim, great job on a repair that is challenging to say the least. Your extra work producing the vids is very much appreciated. God Bless and keep safe.
I had to change the fuel pump on mine years ago and at that time noticed the spare all covered in road crud and rusting etc. that cheesy wind down crank was beginning to jam up. I thought to myself that it would actually be better to not have a spare at all since you would never get that out in a ditch on a dark road with a flat tire. I pulled the wheel and silly mechanism out and it lives in the corner of my garage ever since. So glad it isn’t there when I go to service the diff or brakelines etc.
Thus has been one of my favorite channels for awhile . Ive completly rebuild from bare metal my 00 silverado bu watching these videos and a few others . No more getting ripped at the mechanic. Would like to kniw why I can't use synthetic lube with rtv. I was about to do that.
Thank you for the video and God bless America.
You're a hard worker, there can't be many fishermen who own a full time automotive shop, ha ha.
Last time I did a similar repair was in Entry Level Trades Training 23+ years ago... ah, the memories! :)
Oh wow. I almost have a hard time believing that. I don't get them all the time but they roll in a few times a year it seems like. Do you just send them to a drivetrain shop?
The Car Doctor LOL... we work on VW & Audi mainly. We get the odd domestic car / truck for general maintenance. We will tackle this work if & when one does come in... just thought it was funny that it has been that long since I have done something like that. :)
oh ok. well this one would be hard to pass up. Pretty easy fix and pays great. I hope one limps in to you soon. You may need to get the old rusty standard wrenches out for it.
You didn't show what the problem is or the brake down so I don't understand if I have the same problem
I started using synthetic gear oil about 10 years ago but i was having come backs for leaking covers. I stopped using RTV silicone and now use Permatex right stuff and have no leaks. I hope you had a great vacation, Tim.......NOW GET BACK TO WORK!
I have tried the right stuff and it's pretty sweet. A little spendy but probably worth it. I think the ultra gray stuff should be ok with full synth stuff but your probably right. I'm ready to go back fishing. Work stinks.
The Car Doctor Tim please correct me if I misunderstood - Ultra Gray, Permatex are ok with Fully Synthetic Oil while RTV Silicone get melts and cause of leaking?
The Car Doctor
Permatex makes a gasket maker that is gear lube resistant. Just bought a tube.
I used "right stuff" when I worked for GM in the late nineties. I brought that and loctite 515 with me to independent shops and never looked back. I only use orange/black/blue RTV when sealing isn't all that critical, like 1 hour or less for a comeback.
I've done this repair on my 2004 Silverado. Passenger side went back together fine. Driver side axle won't slide all the back in feels like it needs force. Did not force it. Any suggestions what could be wrong?
Is there another breakdown video that also says what the issue was?
Just like down town buddy, well done , I like the seal holder. Nice to se ya Tim and look forward to spending more time with the Car Doctor. Cheers
Thanks Steve, good to be back!
Could you make a video explaining how to set pre-load and backlash please? Thanks
I wish you would explain what you are doing. As far as the torque specs on all the bolts say for the carrier straps.
I have a serious question. When ever I am making a right turn or anything involving a right turn motion wether it be driving at speed limit or just rolling in a parking lot at 5 mph it feels as if the truck is going to spin out.
really did not learn much on this one... i was hoping for a lot more info on preload of the pinion and how to adjust the side to side of the big ring gear with shims...
I was just thinking I needed to send you a PM to see if you were doing okay. Miss you buddy!
I got unplugged for a few weeks and my brain took a vacation I guess. I forgot how much I missed my community here. Super good to be back and glad you hung in there. Thanks for caring!
Really appreciating the professional work and instruction ... very informative and helpful.
You are welcome!
I have a 1990 C 1500 rwd and my truck squeaks when I give it gas after it warms up but there is no squeak when it is cold and also I replaced both U-joints on the drive shaft but it did not do anything for the squeaky noise do you have any ideas
Also it does not squeak all the time mostly it squeaks when I am trying to pick up speed by pushing down on the gas pedal pretty hard but if I just press on the pedal lightly it will not squeak most of the time
great video car doctor..!!! thanks..
Question. ..on the same vehicle my left axle has lil play seams to spring itself back inward when pulled outward and on the right side play will stay in and out when moved
Good to see you back Tim and good tips on the differential. You looked pretty beat which means you had a great vacation :)
Yes I'm still recovering and trying to get caught up from being gone for seven weeks. Starting to see the light at the end of the tunnel. Hope your summer has gone well.
Amazing video. You definitely helped my butt out.
I just rebuilt my rear differential and my question is after tightening the differential and the pinion and everything should you be able to move the differential by hand
Welcome back Tim. Hope the fishing was good. I'm a Pickerel man myself.
Thanks, good to be home. Not the best fishing season but good time relaxing on the beach.
hey car doctor have a 2002 chevy tahoe 4x4 makes a grinding noise from rear differential when i place in gear only when its not in 4x4 hi.. what could be the problem.
Hi Tim, Welcome Back, hope you had a good season on the water.
thanks Joel, we had a blast but its good to be back.
i have the problems with my van the left tire make noise when running only when I release the acceleration pedal
I have an 03 safari van with AWD , first year of safari or astro with six lug axles and rear disk brakes. I think its the same 3/4 ton axle used in the GM trucks? It starts to make a faint dry bearing kind of noise above about 25 mph but its not to bad , until you let off the gas and coast or slow down . Then it's a louder dry scrap , scrap , scrap kind of noise. All new brake rotors calipers , u joints , rear axle lube . I am thinking an axle bearing ? How can I tell if it's an axle or carrier or pinion bearing ? It's not a bad seal because it's not leaking anything .
Does a 1/2 ton 99 silverado have a crush sleeve to adjust the pinion and are there some type of retainers in the differential case that hold the axle from sliding out?
The forward moving grind can now be heard at very slow movement which sort of pulses and several times per each rotation of the rear tire. So I am thinking at this point it could be a pinion bearing fail.
I recently picked up a 05 Canyon. It have an odd wobble at low speed, if you go over a hump in the road in tries to bounce sideways (hard to really explain) and the passenger side tire will pull in and out about 1/8 an inch or so. Way more than it should. Any ideas?
Have you ever had one in for vibration cause mine will vibrate when i hit 80 if i hit gas stops and sometime i can drive 80 with no issues...
Is this the actual rear end being do. Would this be the same as a 1992 pk pick up truck?
What does it take to remove and replace a rear end for a 1992 pk chevy,Cheyenne pick up it's a v 6?
I have a question if anyone can help that would be great. I have a GMC SIERRA 2006 1500 full size I was on highway today it started making winding noise sounds like it coming from rear I can hear it good in my cab any help would be greatly appreciated
I have a Chevy duramax 3500
And i have strange noice
When i drive is sounds like
Tick tick tick continues
Once i accelerate the noise go off
Only when i slow down those
good video, thanks
would have like to see the diagnoses and break down
man your videos are great. Thanks for sharing your knowlege
Thank you!
Hey you have a life and business to run, youtube is just a hobby, we understand :-D.
Ahh toothpaste on the gear to show the full area of contact, i know its not toothpaste lol.
I was watching EricTheCarGuy setting up the mesh with fresh parts, looks very long winded, buckets full of patience required.
Your appreciated tim, a nice man that does not mind helping us :-D
Maybe those guys across the pond understand but us usa's want our weekly dose of grease and oil from the northern lights. Maybe the Doctor should put up a garage at the shore and do a little double dippin. Blime me that makes me mad well mostly. Brandy kicking in sorry did I go off the deep end. Oh yes how is everyone good to see you all thanks for coming back. BTW zz Harvey is down in Georgia visiting Calvin's Corner72.
nice to see you back .
It's good to be back in the saddle but still wish I could find a way to fish year round but I haven't figured that one out yet. Maybe some of my videos will go viral and I can retire all together. Thanks for dropping in!
what was the torque spec on bearing caps
Torque specification for the differential please.
Do you have to take it all apart to change the bearings
Yes
Good vid good to see you back Tim !
Thank you. I missed you guys.
What are the torque specs on the 4 bolts you started tightening at 5:40??? Anybody know?
Im wondering the same thing
You do not show me the video where the pin goes
Hey car doctor, I have an 04 z71 Silverado 1500 and the 4wd gets stuck sometimes, the rear end locks or binds sometimes and it's not pleasant hopping and feels like my rear tire is square do you know what could be wrong? Plz help
check your fluid for metal and make sure you have the correct size tires. It may require removing the cover and inspecting to find the fault.
Good video! I'm having a noise in my right axle and I think it might be a bad bearing. Sometimes it feels as if the right rear tire is not tracking correctly, plus there is a slight vibration at highway speeds.
I would suggest supporting the vehicle and seeing if there is any play in the bearings. Good luck and thanks a ton for watching my vids!
What vid should I watch on disassembly of exactly this truck
If u find one tag me bud.
@@JustWabertwhat is you're having a problem with?
I figured it out
@@calebhefner6760 my uncle is having trouble with an e shaped clamp or rod lock. He said it's in a reduced spot and can't figure out how to remove it. He needs to disassemble the rear differential on an 07 tahoe.
Never messed with my diff but am actually about to so like wise if you run up on something.
I watched to learn able pinion bearings but that part was done.
I'm a new subscriber thanks for the video great information
Welcome aboard! Thanks for watching my vids.
Wish you woulda made a video disassembling it.
hi tim! could you please tell me what a bad rear axle bearing sounds like this is a rear differential a lot like the one in this video of yours!
A bad pinion bearing sounds a lot like a jet engine increasing in volume with speed.
Did the E-brake mechanism go into the 6 o'clock position or the 12 o'clock position on the passenger side on this vehicle? I have a 2003 2500hd and am wondering because my passenger side and drivers side drum brake shoe guide plate are inverted. They are the same plate but they are mounted onto the axle housing in opposite positions. My pass. Caliper is not mounting into the rotor correctly, the more I snug it on the more it knocks the rotor off kilter. Have a new brake shoe guide plate in order.. can't think of anything else that should be causing this.. Auto store sold me the wrong caliper perhaps? Any insight would be appreciated.
Are the caliper slide bolts operating freely? Sounds like a frozen slide bolt on the caliper mount.
Thanks for replying.. The prior owner put the wrong goddamn rotor on there and instead of looking up the correct rotor for the duramax I ordered a new one of the wrong one, and replicated the problem. I did some research and busted the measuring tape out and low and behold..
Your videos are priceless keep it up!
Glad you got it figured out. Thanks for watching.
I wish you would have shone how the axle bearings came out!! I'd rather be fishing anyway,
can a differential be lengthened on a 94 g30 van?
welcome back Tim...hope you got some fishing footage coming up
Thanks, I shot more footage than I caught fish but it was a fantastic season. Still good to be back. I'll share some highlights soon. Take care.
Hey Car Doctor. Thanks for the video. Do you have a video showing how you set the pinion depth and pre-load ? Thanks
Where can one, purchase to seal installer tool. Thank you
never tackled a diff before but my dads silverado has a noisey pinion bearing and figure i should just do all the bearings, if i simply put the shims in the same spots and preload the pinion corectly i should be ok?
front or rear? The front independent diffs have problems with the lock rings breaking and side bearings coming loose. but the year is pretty straight forward and yes, if you get the shims back the same it should be perfect...but never hurts to run some indicator around and be sure.
rear no issues with it minus the pinion whineing when you let into the throttle hopefully there is no carnage when i get in there
I did not see enough to use vid to my advantage. I guess the pro mechanics got it but not every day joe wrench it. Regards
1997 chevy 1500 conversion rear noise whining get t ing louder.gonna raise it and put in gear.already replaced u joints.not surd now.i didnt check nut at fron or maybe wheel bearings.i just bought it and not happy.now i know why the people wouldnt shut up while i was tezt driving.any suggestions?i need some help.thanks
Maybe wheel bearings or internal of the differential I suppose. Hope you get it figured out
did you figure the noise out yet? I have the same problem and its pretty loud at this point. Im thinking it has something to do with the inside workings of my differential. The differential was low on oil so i filled it bu the noise is still there
I have a 2000 Z71 that I started getting a surging rubbing noise sound coming come from the differential. I just changed the Ujoints and the axle bearings trying to correct the problem and the noise is still there. (They needed changed anyway and the seals were leaking a little so not wasted time)
The sound is consistent with speed and is only noticeable from about 0-30 mph. Above that I think it blends in with road noise or the surging becomes one sound and it's not very noticeable. But below 30 it is to the point you can hear it outside the truck.
Have never setup a rear diff so I'm in uncharted territory. Not afraid to tackle it but can I change pinion bearing and race along with main carrier bearings without checking backlash or pinion depth or pattern?
Hitting the brakes doesn't change the sound except for slowing the surging down consistent with the speed. Also turning left or right doesn't affect the sound so I'm assuming pinion bearing or carrier bearings?
Any tips or advice would be greatly appreciated.
Brad Mann Sorry to bother you. But I saw a comment you left about a surging running noise coming from your diff. My truck is doing the same thing. Just wanted to see if you found a fix. Thanks
Mine is doing very similar thing (2004 silverado) my noise is consistent with my rpms.. I can let off the gas, even though I might be going the same speed down hill the bearing growl is slowing with the rpms and raises with rpms..
I have a 1994 s10 blazer has a vibration in the rear I changed the u joints no change
I wish you would have said how tight you tighten torqued
Hey Tim how u doing man I just wanted to ask what was the symptoms of this failing pinion bearing.. Im currently working on my 99 Chevy Suburban that has a drive line knock.. Recently shaft jumped off at pinion due to a single bolt backing its self out of the flange I replaced the U Joint but problem still exist.. Did this vehicle that u worked on clunk and knock also I'm just looking for direction.. Also my Pinion has a small bit of side to side play of about 1/4 of an inch ...Thank you brother
I think this one just had a bearing type growl.
The Car Doctor ..Hey man thank you for your response
Hello, really cool video, down anyone what is the torque used to for the bolt on the braces
How much does a job like that normally cost
They are less a pain in the head & neck if you remove the spare tire first.
the next time you remove the spare tire so you can work better
but you did good job
latinpaver did you watch the video? He addressed that.
How do I know it's a rear bearing? I have this clanking noise when I drive on my driver rear (02 Suburban). Went from when I hit a bump to almost constant now.
I have a loud similar noise on my 01 Tahoe! It doesn't drivedifferently, but it makes the noise.
what are the specialty tools that are needed for this job?
I forget sorry
You are a great teacher and great in front of the camera !
What negative result from introducing a synthetic gear lube ?
Is it TOO slippery ?
My 99 calls for synthetic ??
Waths the torque specs jammy? You forgot to tell
Jammy?
Cool, I have to do this on my old truck. Gov locker has to go, Ill put in a Taiwan Eaton trutrac I need a good puller / installer to do the axle bearings
I used my 20 ton press and a bearing knife to do the pinion and carrier bearings. My problem was the wheel bearings which blew apart while pulling and I had to use a torch to get the races out. Everything else went smooth as butter. I like the Yukon or eaton carriers but this truck isn't worthy. Good seein you.
I'm so glad you're back. I saw some interesting footage of you on Jake payne channel, lol. What happened to that guy? He doesn't post anymore vids. Looking forward to your next video.
Super sorry to say that Dr Jake passed away a few months ago. I sure miss him.
Did I miss him checking the back lash? What do you do if the pattern on the paste is not the way you want it? But a very good video.
Pull thr caps back off and rotate it a bit
You should cut that spare tire hoist cable and replace it, the are a POS and the replacement form Doorman etc. will be better and they are cheap; OH and your customer can now get his spare tire down if he needs it....
About what does a rear diff rebuild like this cost, parts and labor ? Thanks,
$1300+ unless the carrier or ring and pinion is bad.
i just did it my self on my 2000 silverado tolal cost 148$ for parts sure shops gone rip u off lol 1300 u buy used diff for 400 lol
yeah, I would do mine myself as well, except I don't have the pinion depth gauge nor the backlash gauge.
Did a 1992 gmc sierra c1500 SL with the 4.3 700r4 come with a g80 lsd or no?
not sure
Ok
I bet the dealer could tell you
Ok
Daniel McDaniels look in the glove box for the Factory RPO codes there's a sticker in there it's in alphabetical order go down to where the G's are should say g80 if it came with the government lock , other g codes will indicate factory gear ratio such as gt4 3.73, gu6 3.42, gt5 4.11 and so on.
what was the torque specs on the carrier bolts foot lbs
I forget sorry
Its ok thanks though for replying
Good job.
Thanks!
Thank you
Good video hope the summer was good for ya. We have been busy #4 son has made it thru boot camp and MCT. We put in a garden and have been enjoying the pool. BTW I did a vid of the PS rack replacement in my T&C if ya care to check it out. TFS
Will do. Congrats on the boot camp graduate!
Thanks Brother.
USMC. Nice
Yes sir, we are proud of him.
+The Car Doctor hey do you love your job because I do but can't find anyone as passionate about the job as me I often wonder why tat is
Cool
I got a new one for you...KEWL haha
is that white lithium?
Gregory Johnson white lithium is a smoothe grease that works well for moisture and heat and doesnt get as stiff in cold weather. There should be an good description of it in Wikipedia!
Where are u located I need u on my truck
Alaska
👍👍
move your head so i can see what you are doing.
Ah, I'm sorry but this isn't a live broadcast.
why the hell are we watching the back of ya head.
Better than watching my face
Video says differential bearing but you didnt show us the work you did on a diif bearing. Honestly just frustrating that i watched u do nothing to do with a bearing. U just put it back together and stood in the way of the camera.
stop eating cold cuts there seeping
