For the moment, Stazi has driver's side hubs with bearings already pressed for $50. I don't know if he can get the passenger side or not.
Either way..
if you go through Bill and get a bearing, you will have to pay to have it pressed out, and the new one pressed in. Depending on what labor for removal of the hub and pressing cost, you can get a new OEM hub with bearing pressed from Steve at Tousley ford for 150.00 and some change (shipped) which eliminates the pressing, and all it is then is a simple swap of hubs. I don't know the Bill J price on a hub/bearing assy, which is why I mention Steve.
