Re: 12 bolt rebuild + Eaton

The carrier and pinion bearing will have to be pressed off. I'm sure you could have your local machine shop to do this. If you have access to a press make sure you get the carrier bearings a little past flush or it will not be seated all the way. On the pinion I removed the old bearing off the old pinion to retrieve the shim underneath. The original shim is usually the right one for the job. A neat tip if you have to play with different shims to set you pinion depth waller out the old bearing so it will slide on and off so you don't have to run to the press or machine shop to try different shims.

Installing the pinion bearing: They make a $100 tool that looks like a real tall socket to hammer or press the pinion bearing. I used the old bearing I wallerd out.
