Jedi,
Not sure what the differences are btwn 2wd and 4wd rotors but the Advance Auto computer brought up 2 rotors and asked what size the rear brake shoes were. I did not know so I just took the rotor in and made sure the ones at the store matched mine. Luckily they had 2 left in stock that were the correct ones <img src="/forums/images/graemlins/smile.gif" alt="" /> (sometimes I do catch a break). Anyway, as airrikk stated you have to remove the hub from the rotor, luckily I have an air impact wrench otherwise it would have been a tougher job to get the bolts out. Sounds like airrikk found an way. You'll likely need a breaker bar or large ratchet. Then I had to drive a thick metal chisel in btwn the 2 parts to get them apart. As for regreasing the wheel bearings, I have one of those bearing packing tools (just 2 plastic cones w/a grease fitting, there's a pic in the repair manual). It makes repacking a little easier and it helps in getting all the old grease out. Should not be more that 4-5 bucks at the parts store. Good luck,
