Before pulling that rear apart, you really need to blueprint it. This is simple and will save whoever a ton of time.
Clean the gears with brake cleaner while it is still together. Mark with gear marking compound and rotate the carrier both directions a few times. Take digital pics of both coast and drive side of ring gear. store these for future reference. Measure the Backlash and record. When tearing down take notes of each carrier shim and the pinion shim. These notes will help you put this rear back together much faster and right. Tom
