Just as a note, if you're going to dig into the bearings etc - you'll need a 54mm socket. This also corresponds to 2 1/8". May take some digging to find one locally, so just wanted to warn you. Sears has them but a little pricy since they're Craftsman. Search here for "54mm" and you'll see hints on other sources and explanations of what's involved. Good writeup here in Tech on 4x4Wire.
