GM 10 Bolt Rear End Rebuild Part 1

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.

As usual there are some bumps in the road, but I’m able to overcome them. Well, most of them.

This video will apply to all GM 10 bolt or 8.5” differentials.
