Awesome to watch a mechanic that knows his stuff!

I'm currently doing this for the first time, and was thinking about the pinion depth measurement. I figured if you have the tools, you could bolt a piece of MIC-6 across the caps, using that as a straight edge, depth mic down to a gage pin at bottom of carrier bearing bore, depth mic down to pinion face, subtract, then mic the carrier race dia and add half to the measurement. If I had the foresight to order some tooling plate ahead of time I woulda tried it 😆

No tats,no language and good info. This channel is a keeper!

What procedure, did you use to get the correct backlash pre-load of 14"-19" in. lb. when you were setting the pinion depth? (crush on sleeve) You mentioned it was tricky, and not to go to much or you would have to get another crush sleeve to start over. Did you use a ratchet, and socket on pinion nut a bit at a time? or?... This would be a helpful, perhaps critical, step you did not demonstrate. Other than that, your tutorial was easy to follow along. Thanks.

Good video! I have one question and thinking out loud here. Is it possible to get close to the pinion depth and spacer needed by measuring the old pinion head with the original spacer and lets say it's 3.250" in over all length (the head with spacer). Now measure the head of the new pinion and it alone is say 3.100". This would mean you would need a .150" shim to get the original 3.250" distance. My logic here. The new pinion bearings and races have to go back exactly in their original locations. The new pinion and carrier all have to be machined to a very tight tolerances or it would not fit the housing. So the only thing that is changing is the thickness of the head of the new pinion. Get that close to the one that came out and I think you have the thickness needed for the new shim. What do you think?

I use a steering wheel puller to get the yoke out ,take the caps off the joint locks,and run two bolts thru the holes if the go all the way thru.If not use bolts that are the same thread as the caps.Use the side by side slots on the puller.

Ok here is where I am confused. I have done every rear end in my Chevy trucks suburban and Tahoe 10 and 14 corporate rear end. All lockers or the g80's. I know that Eaton makes them for gm and are not interchangeable with conventional gm differential. The pin is .010 larger spider gears have 10 teeth instead of 11 and yada yada but here's my point did Eaton sell the rights to gm because I pulled my drum brake g80 out to put the 8.6 disc in and it is a g80 also but has NOTHING in common with the 8.5 except the ring and pinion. Everything in the 8.5 is bigger parts wise and the 8.6 is just like a conventional diff not like the Eaton 8.5 that I have always dealt with. I thought someone tried to rebuild it with conventional parts til I tried the pin from the drum brake and it's to big but it's got the access holes for the tumbler and mechanism so it is a gm doings but I don't get it. Gm start making them out of their conventional diffs?
