In todays video we fix my dads nbs gmc sierra. The pinion seal has been leaking for some time and we finally get the time to fix it. This video shows how to replace the rear pinion seal in a Chevrolet silverado and gmc sierra. This works on many years and if your rear end is leaking this may be your issue and fix. This is a common spot the silverado and sierra rear end leaks and is a cheap and easy fix. It can be replace in your driveway or on a lift like we used. This process will also work to replace pinion seal or fix leaks on Tahoe, Yukon and Escalade. This is the easiest video on how to replace rear pinion seal on youtube in my opinion. Its nice to help my Dad since he is always helping me.

This man must be telepathic. My pinion seal started slinging a little fluid yesterday. Impeccable timing. Awesome video
Lol. Good timing
Dad's got a sweet ride. I'm watching this currently in a tattoo chair hr 3
Lol. Yeah he does
Thanks again Travis for another helpful video.
Thank you for watching
Great video man wish my dad was still here good times
Thank you Daniel. I'm lucky to have such a great dad.
Switched out my seal today. Nice to have a competent, to the point video to watch as reference. Thanks!
Awesome. Hopefully it helped
Went to weld a magnaflow under my son's 2000 rcsb and found it had been slinging diff fluid on the gas tank and a little on the exhaust. He and I are gonna tackle it this evening. Never done one either, so thanks for the video, Travis!
Thank you
Thank you for the video. It’s definitely greatly appreciated.
Glad it helped
Your a good son! I’m the same for my family too when a car or anything needs fixing if you can, pay it forward!
Thank you. Yes he helps me out all the time.
Very helpful video, I've got a 2006 Silverado leaking pretty good. Thank you for the great demonstration!
Thank you
Wow I owe You. Great video. Not too many home mechanics have a 32 mm impact socket,ran to harbor freight found one for 5 bucks. Had the job done on a Saturday afternoon. Thanks again for the encouragement. No more leak...
Glad I could help
That GMC looks beautiful with the bed that it has on it
I like both
Great Video… Been putting this project off for my brothers truck for about 6 months, your video made it look so simple I’m gonna get it done this evening or first thing tomorrow morning.
Thank you. Yeah it isn't too bad.
Outstanding!
Thank you
Great video it helped me to replace the same seal on my gmc canyon, thanks for your helpful video,
Glad it helped
Will be doing mine soon!
Several on the road need it.
Very informative Mr T. I have to do this on the WS6, it went bad when I dropped the suspension. Pinion angle way off, addressing this issue with BMR products, adjustable torque arm, LCA relocation brackets, etc....
That sucks.
Thank you so much for the help. My front is leaking on my 4x4. But my Haynes manual says that this procedure applies for front and rear. So thank you so much. Life saver brother
Thank you. Glad I could help
My drive line came off today on the freeway great video now that im going to replace the ubolts might as well get the seal replaced
Holy cow. That's crazy
I put a junkyard axle gt8 g80 optioned and it needs one of these seals badly it leaked about 8 ounces of diff fluid in just a couple months time and that's cause I don't even drive it often I was debating whether or not to take it to my mechanic but, this seems like an easy enough job for me just need to rent a puller though thanks for the vid brother!!
Not too bad. Definitely give it a shot before paying a shop
Good Thursday evening TW. Working on dad's truck.. awesome.. I like the GM forest green on vehicles. It's a sharp color 👍🇺🇲
Thank you. Yeah. I tried to buy his first.
@@TWAMotorsportsyou'll find one like it..... I'm looking forward to video of the transmission replacement in your dad's SSR...if I'm not mistaken I think they have the corvette motor in them sport trucks.. I remember when they first came out.. cool looking 🇺🇲👍
It's the early one with the 5.3
@@TWAMotorsports 2001. Is it?. 4L60e. M30. Automatic transmission I believe...I used to work on those back in 01 when they came out..
They came out in 03 and his I think is an 04. 4l60e
Good video. I'm glancing at this because I haven't done one in ~30 years and mine is leaking (former GM Master Tech) and I'm just looking for a refresher on fastener sizes and such. Mine is leaking by the splines, as evident that the nut is shiny. The tip I have is to use Loctite teflon pipe thread sealer on the pinion splines before reassembly. It might eliminate a come-back.
Time to get it swapped it sounds like.
My 2012 GMC Sierra 1500 rear axle pinion is leaking oil, it looks a lot easier than I thought. Did you polish the yoke sealing surface for the replacement seal?
No we didn't
Did you have to install a wear sleeve on the yoke? Good DIY video.
Not that I saw.
Nice video bro do u have a video on adjusting transmission cable
I don't
Good job, everything done to the book except should have coated splines with rtv (ultra gray) probably where the leak was. Other than that good work.
Thank you
0:16 Any idea why the bottom rust like that I have a 2003 gmc sierra same color and its been a florida truck all its life and it has rust build up right underneath the door everthing else on the truck is ok
Dirt gets between body and panel. Add a little water and boom.
Gained some confidence to do it for the first time after watching this video
Thank you. Hopefully it helps
I just changed mine about a month ago in my Black 2000 stepside Silverado.
Not too bad of a job
@@TWAMotorsports No it wasn't too bad. I ended up taking the rear diff cover off, and noticed one of the spider gears had a couple chipped teeth. I still need to go back and fix that though. I bought the truck about 15 years ago with 65k miles on it and now it has just shy of 240k. Still stock 4.3. Been wanting to do an LS swap and lower it for several years now, but haven't gotten around to it. Maybe someday. Its been a good truck though, people ask me all the time if its for sale.
That's crazy it chip the spider gears.
I got a 92 Chevy 4.3 v6 well it belonged to my pops and he messed up the seal and replaced it but didn't do it correctly, he was dying and wasntv in his right state of mind well I got the driveshaft off the truck and didn't know anything about aligning it up but I'm trying to figure out if I should drain the oil completely and replace it or just fill it up? Also I'm not sure how much torque I put on that nut that holds the yolk onto place? The parts I have right now are new including the nut.
I'm not sure on those years but I didn't torque, just counted the turns. I would drain and refill
Same here i don't know anything about these trucks and nobody will help me, I've got to different books on these trucks and both or different from each other hahaha which makes zero sense? And I'm trying to figure out what is a ring
Gear? I TH-cam and Google it and still don't understand what it is or what it looks like? I don't know shit about this stuff and didn't have a dad growing up to show me anything. I don't know what to do?
Probably should take it to a reputable shop then.
@@TWAMotorsports if I had the money hell lol plus it's sitting in the yard with no differential fluid and it's not legal
Gotcha
Can you do the u-joints next time? I've been wanting to change mine on my 2005 Tahoe. Thank you
If I have to I will do a video for sure.
@@TWAMotorsports Thank you. Mine's not broken or anything, but I just want to be proactive. She's only got 175K miles on her and I want her to last 300K
His are all original too
Hey I’m trying to loosen the pinion nut rn but the yoke is rotating aswell
Wheels need to be on the ground
@@TWAMotorsports they’re on the ground now and stilling moving thought if I put parking brake would help but not teally
Parking brake is the only other option I would suggest
I took my 2006 Silverado 1500 to a shop about 7 months ago and paid them to replace this seal. Now, I noticed a few days ago it started leaking again. I assumed they checked the bearing and the pinion yoke. It didn't leak right away, so maybe it is just a faulty seal or installation issue? It is under warranty yet and should be able to take it back, but what do you think about this?
Hard to trust shops doing the right things these days
My mecanic changed the u joints and seals on both sides of the shaft, one u joint was about to brake and I start feeling vibrations ,but I think he did not marked the way it was and and now, still vibrates but in a diferent way, how can I fix this? How can I know the original position of the rear end joke?
You can't. Have to pull apart and mic everything. Not for the novice mechanic
Thanks for your response, I checked my self and turns out that the u joint was l little loose, I loosed the two bolts and hit the u joint cap that looked flat and it when down/in about 1/8. No more vibrations 😊
@rickyricon2787 👍
Did you force that nut back to the original position? I did my truck the mark is exactly the same as your.
Counted turns.
@TWAMotorsports I guess I should say it didn't go back exactly the same is just a bit off is like just a little bit
@pedropadilla686 may be fine
Obs led install video?
Not for a long time
That truck is sweet, I don’t blame him for not selling it to u lol!!!!
Lol. He said I would just sell it
Puller , what else can I use ?
Puller
🤙🏻🍕
What happens if I don't mark the parts before I remove them
May not get it back to where it originally was.
I couldn't get the seal flush on my 90s Chevy I just went ahead and put on the yolk and didn't know anything about lighning or marking anything up I just put 120ft lbs into that bolt a couple people told me to put only like 10-30 in lbs which there's NO WAY it's in lbs? I most I could put was 120ft lbs so hopefully I'm good? I'm not a mechanic and have zero help with no friends.
Time will tell I guess
Wich nut is the pinion nut?
Only nut we removed on rearend. Big on in the middle we counted the turns on
@@TWAMotorsports thanks. I was watching some videos and they were showing a washer and a nut inside of there. Thought it was one or the other.
I’m Mr. strong guy I don’t know what a pry bar is, never used one before ☝🏻🤫
Chock the wheels and parking brake on when removing driveshaft. Vehicle can roll and things get ugly quick.
Thank you. My lift has them built in.
Now I can stop topping up my gear oil and get this fixed
Definitely would be nice
What the “thread count”?
Probably different on each
I’m not understanding, the manual asks you to document the breaking torque (I work in an Industry that is torque dependent). Breaking torque is a qualitative value as it’s not a constant. I have a decade of research proving breaking torque is qualitative. This is my question, what is the torque speck for this bolt? I understand counting the threads. Wtf is the center bolt torque value?
No idea as it isn't the by yhe book method to fix
U ever had an issue with replacing it & then months later leaking again
Not so far
I avoid this and just went and brought a rear end from the junk yard cause I didn't have the knowledge and tools to do the pinion repair
That's expensive
