how exactly does this tool work.
looks like it slides through the hub and then catches the hub cup with those tangs. then what? hammer on the back side of the tool or something?
where can i get the replacement cups?
is it usually the cup, the bearings, or the cones that need to be replaced to make a bumpy hub smooth again? i never see bad stuff on the cups and cones but there is always some bumpiness going on...i guess that leaves bearings huh?
