Axelshaft Bearing Problems
I have an '81 F-150 with a 9" diff, and have been rebuilding the entire rear end. I need to know if I should replace the axelshaft bearings or not. Is the bearing cup that sits in the axelshaft housing supposed to be firm and unmoving or should it be able to move? The bearing is one of the early-model tapered fit ones.

Should be firm. If it's loose, it's been slowly rotating and wearing the axle housing. A little bit of loctite or something like that may stop it.
If the race looks shiny with no black pits, and the bearing spins smooth, I would reuse them. My old 80 had a 9 inch, with the tapered wheel bearings, and I went to every store in town and no one carried the tapered roller bearing anymore. So I just bought what they were giving me and it fit fine. It was a all-in-one regular type bearing.

I found some "Bearing Mount for Worn Parts" product yesterday and it works perfectly. The local Lordco carried the new bearings but wanted $150 for one. The old ones are in good shape, so it should be fine.
