Hey hotrod, yeah I tried describing the flat washer with tabs. I do have that on there and the nuts remain on the spindle when the drum slides off. Dave, the bearing races seem to be properly seated and the snapring remains in the drum when it slides off. Yet, the bearings remain on the spindle. Perhaps the snapring that was originally in the drum was incorrect allowing the drum to come off while the bearings remain on the spindle? Ill have to take both sides apart and compare the snaprings because the right side has given me no problems. I put both sides together identically and the left side is the problem child so I'm thinking its at least a problem with the parts and not the operator. How does that hub portion come off the top off the drum? Anyone have any ideas?
