How to install or change or replace gears and bearings in a rear end or differential

Installation of carrier bearings, pinion bearings, ring and pinion and a crush sleeve are covered in this video. The main tricks given in the video are about the actual set up bearings. The rear end being worked on is a 8.5 inch gm 10 bolt out of a second generation f body.

Great video! I have a bad bearing in my 73 Camaro different. Not sure I am up to rebuilding it myself. Excellent info here. Are you located anywhere near Maryland by chance?

@jmiles1960 I'm in Wisconsin. Glad you enjoyed the vid.

Excellant video!! BTW what type tonnage press did you use and what is the minimum I need to press bearings into pinion shaft? Thanks!

[Oldsmob455]

@TheCarmanguy My press is a 20 ton. Not sure what the minimum would be but it really isn't a hard press so you shouldn't need much. Good luck.

Really good video. Thanks for taking the time to teach people the basics

@09daytona The idea is to open up the checking bearing just barely enough to slip it on. It's certainly isn't a perfect or final pattern but it's close enough to give a idea where one needs to be. The final pattern of coarse needs to be checked with the bearing that's pressed on. I could have pressed the final bearing on and off all 4 or 5 times but that probably would have resulted in a trip to the bearing store. Bearing separators are not easy on roller cages and sometimes bend them.

@Oldsmob455 I am aware this is a setup bearing and that you exchange the setup for a unground permanent at final assembly. But the 2 bearing bores are different diameters and the 1st allows lateral movement due to the enlarged bore, resulting in a false wear pattern.

@09daytona Re-watch the video.  That was a "set up" bearing. A different bearing was pressed on for the final fit.

Hope I'm not being picky with this but if you enlarge the inside diameter of the pinion bearing wouldn't that promote deflection of the gear itself under load and give a false wear pattern on the ring? I realize the clearance might have been only +.001 but that would be +.0005 of movement.

Still a great video though. Makes me remember why I don't attempt stuff like this laying in my driveway and prefer to pay a shop :o)

Thanks for the video, I am learning this in class and a little extra knowledge always helps. :)
