trying to visualize the issue you guys are having-- i take it the bearing races and the center protrusion are loosening up with the cheap ones? I have a few of those lying around and could never see a reason to use something like that compared to a fully sealed bearing. The upgrad ones -- the snap ring acts as a stop against the hub's outside or inside edge? Is there anyway to remove the snap ring and get them to seat flush with the hub edge then stake them in place? if the fit is good to the inside of the hub, green loctite (for sleeves etc) might also be an option.
