Axel shaft hot

The simple, truthful answer to your last post is.........You need to read THE BOOK

Go over to MyMopar and download a service manual. Free.

Some Mopar axles use tapered bearings which must be adjusted for preload on one side, which pushes clear across and loads the opposite bearing on the other side as well

If the bearings have been converted (by a previous owner?) to ball type bearings, the preload system will no longer be used.

But some axles use straight needle rollers which run directly on the axle, and are retained by "C" clips in the differential. If that is the case with you, it might be as simple as low fluid level, and has torn up a bearing.
