thx for the replies. yeah it is the rear. and it doesn't look tough....wish that grage was heated...but other than that the only thing that is making me pause is that the bearing needs to be pressed on. i was looking at this yearterday http://www.stu-offroad.com/axle/usad44/usa-1.htm
i also found some forum posts(not on this site) about people freezing the axle and warming the bearing and then taking a pipe and hammer to it and driving the bearing on.......that just doesn't sit with me well. i just don't think it is a good idea to pound on the bearing. but if i am told it will work i can give it a try. i am also going to check to see how much a dealer would charge todo either the whole thing or see if they will just press the bearing on for me. what do you guys think?
