thanks guys, This help was for my brother so I was helping him out. I found a thread with the info. On the 3/4 tons you have to remove 4 bolts and pull the rotor and hub assy. out together. We got 3 of the 4 bolts out but the last bolt is so tight we broke 2 sockets, used my IR impact and a 3/4 impact and still cant get it loose. He is going to have to take it to a shop. Thanks for the quick replies.
