ok, so i have to do this... my front left sounds like an old skateboard.

everyone seems to be buying a whole new hub. what is the reasoning behind this? do you really have to replace the hub, or just get the old bearing out and the new one in?

also, pressing bearings, is there a special tool to do this or do you have to take it to a shop? i helped my buddy disasemble the hub on his Bronco and he just bought the special tool (looks like a hole saw) that would screw a colar onto the bearing to hold it in position.
