Ford 8.8″ Differential Complete Tear Down #FairmontProject

All of the information in this video will also apply to the GM 12 bolt as well as other differentials of this type.

The #FairmontProject needed a new differential. The stock 7.5″ wasn’t going to cut it. So I got an 8.8″ out of an ’86 Mustang. The Mustang rear end had Traction-lock, but I’m not reusing that carrier. Since I’m upgrading to 31 spline axles, I needed to upgrade it anyway

Perhaps at some point I’ll go back and do a rebuild of the stock traction-lock differential, but since I was upgrading anyway, it really wasn’t necessary.

***I show how to make a ‘set up’ bearing in this video. I learned the hard way that this may not always work out. If you are going to use a set up bearing, I recommend purchasing 2 new pinion head bearings and using one for set up. You can purchase set up bearings separately, but they are way more expensive than just getting a second bearing.
