Same with the races, right? I'm not replacing the bearings if I don't have too, but preliminary inspection, I think I have a bad one.

The inner Bearing is the one that is pressed all the way onto the shaft, it will have to go to a machine shop to be removed and replaced. pressing it on is very touchy as it can get cocked and will jam if not replaced on a press that applies even pressure. The Cup for the inner may be installed using the same shim settings, as the tolerances the bearings and cups are made to a very tight tolerance that is not enough to alter the depth of the inner cup. The outer bearing is the one where the preload is determined by adding or subtracting shims. It is best to order a pinion gear shim pack from your Jeep parts supplier. Adjust the preload before you install the pinion seal, then install the seal once it is adjusted. Pay attention to where the slinger on the pinion shaft is located, follow your manual.

If so you can get external shims to move the bearing cups [adjust the crown wheel positioning & bearing pre-load]rather than internal, under the bearing cone type, which makes adjustments a breeze.

If the differential goes in without having to force it, the preload is likely insufficient and you will have to remove both bearings and shims and start the procedure as shown in your manual.
That is what I said. Joel is not the only person who ever did this task.you can get external shims to move the bearing cups [adjust the crown wheel positioning & bearing pre-load]rather than internal, under the bearing cone type, which makes adjustments a breeze
