Just need to know if I need to remove the bolt in the center of the rotor. I think I don't but need to know for sure. Once I remove the caliper the rotor should just slide off, correct? I know these rotors on the 4x4's are a bit different than the 4x2's. Anything else I should do while i'm at it? Also, is it possible that the inner pads wear faster than the outers?

 

To get the rotors off of a 4wd you have to take the caliper and caliper bracket off. You don't have to remove the bolt in the center. That holds the cv shaft in place. After that the rotor just slides off. Make sure you use locktite on the caliper bracket to steering knuckle bolts. The caliper to caliper bracket bolts don't need it.
