I know this post was a while back, but if youve not gotten around to doing it yet, ive done them before. Its easy to take the hub flange out the hub, but the inner bearing splits in half. You can cut them off with a grinder, just be careful you dont cut into the shaft. The most difficult and time consuming part is getting the outer part of the bearing out the hub, it took me quite a while to grind away at it with a dremmel. Theres also a spring clip on the inside of the bearing that you can remove with long nose pliers. When knocking the new bearing into the hub (assuming you dont have access to a press), make sure you only tap the outer bearing and not the inner or youll damage it
