Well I got the bearing off well my dad did with our air hammer; the other one in the hub was a pain in the ass. Just to get the bearings off took us probably 1 hour or, mabye even a little more. I clean up the hub, the axle and, the metal tube that goes over the axle before putting everything back together. Before you ask I did lube everything up really good. Wow I am ammazed at how well it performs the axle doesn't move any more and, they guy that buys it from me will enjoy it very much.
