    Question diff questions

    Putting together my 1980 dana44 and I have a question. What exactly is the pre load that I am looking for with used bearings? The bearings in the diff I'm rebuilding are in amazing shape, the cross pin isn't even worn. Online the pre load is recommended at 14-19 inch pounds. My book says 15-35 inch pounds, which is for new bearings.

    Suggestions? I want this diff to last.

    The bearings are still 39 years old. I would change them.
