It may be that you just need some new bearings. I figure they should be readily available from other sources. Fastenal has bearings, and will ship-to-store any you order for a pittance(shipping), while to your door will cost a bit more.
If you take it apart, and the housing is good, and the shaft is good, just replace the bearings. You'll have to drive out the old ones, etc, but it's not super difficult.
Warning, in case you don't know, do NOT put side load on the center race. It will destroy the bearing. Light tapping is ok, but not sledge hammer blows, except to remove the old, stuck-in-place worn out bearings in which case you don't care.
