This is (Episode 5) of the #ETCGDadsTruck Series.
In this installment of the #ETCGDadsTruck series I rebuild the axle assembly and differential in my GMT400 with a 10 bolt rear end (8.5”). This includes replacing the gear set, the differential (with limited slip), axle bearings, pinion bearings, differential bearings, and all seals. It includes all the tools and torque specs you will need. I also show you how to check and set backlash and interpret a gear tooth pattern.
This video will apply to all GM 10 bolt or 8.5” differentials.

A lot of wasted time, but good video
I put together my SM465 and to get the main shaft bearings on the shaft, I had.the shaft in the cold garage and I put the bearing in a cylindrical tube and put a heat lamp on it for.30 minutes and they slide right on.
How come the crush sleeve on my 8.2 10 bolt is longer?
Curious to know .im in the process of rebuilding my rear diff in the 2000 Silverado 1500.its a open diff.i notice the spider gears in the middle slide up and down a bit .is this normal
In the factory 1997 manual it states 90 ft/lb for the ring gear bolts and 60 ft/lb for the bearing caps . At 23:16 in the video you stated 60 ft/lb for the ring gear perhaps you confused it with the caps spec. (Page 4B2-14 of manual) Great video, learned a lot just want to make you aware of a possible discrepancy. Thank you.
rebuilding rear ends is more of an art form..i thought i knew what i was doing and had one blow up within 10 minutes of going down the road lol….
So much for me rebuilding my Z71 rear end. Been turning wrenches for 36 years but this is just way to much.
Felicidades excelente información y muy clara y fácil de entender y tiene un bonito humor
The shims on either side of the races of the chunk, do you have a part number for those?
I actually call them pacman clips
I had the same Diff in my 05 Silverado Z71 4 x 4! At around 135,000 miles I started hearing a little moan from the rear! So That night I put it up on the lift and removed the cover, I could not believe my eyes! The differential was literally cracked all the way around, Yes it was literally two pieces! I never went off road or towed anything heavy, That diff would always lock and unlock when it was supposed to, But they are not that strong!
Is the locker in the 3500 Silverado stouter?
3:23 close your eyes and volume all the way up
Can I change the spider gears in there without actually taking the carrier out of the housing. Just curious. Mine ate the driver side spider gear
If you can take a photo before you remove stuff ….. helps when you have a longer project because you know what it look like later 🙂
I think they call those smartphones those days LOL
Holy shit! Good to know!
Should have got a pinion setting tool from Ratech, $29 and can save hours of getting pinion depth right and no guessing.
From hence forth, Call me………..
some times your a nut case ,,"butt" what car guy isn't? you gave some great info !! thanx
my carrier will not turn to remove the clips that hold the axe in, but the wheel will turn with a lot of help. what can i do to fix it?
Hey Eric, I’m stuck trying to get this pinion gear out. I’ve been following along every step but this pinion gear won’t budge like yours did. I upgraded to a 4lb dead blow and smacked it for a good half hour but nothing.. any suggestions?
I Am having trouble getting axle to move in enough to remove c clips. have i missed something? PIN IS REMOVED
