I am replacing my axle. Bought a used axle. That showed up with some pitting over the outer seal surface. I had that fixed. Then I installed the axle. I was suspicious of the outer bearing surface but I didn't think I would find another issue on the same axle. Anyways, it seems that probably at sometime in the past the outside bearing may have frozen on the axle and the axle spun on the inner race of the bearing. Usually you have to tap those bearings onto the axle. This bearing dropped on there with no effort. I see indications that the bearing surface had something spun on it. I put the axle in the housing and I can wiggle it in the bearing : ( It isn't much but I can get it to clunk up and down. I don't like doing things over and that bearing is in excellent shape because I put it knew in there and it is well greased. The problem is the axle shaft. I think it wore a few thousands off it. Hmmm. What should I do. Start over??
