Thanks for the quick reply. That is the method that I used to sheck the balljoints but I wanted to be sure I was doing it right. It is not so much the tapping noise but the wheel bearing noise that bothers me. They don't really seem related other than they are both in the frontend somewhere. As far as wheel bearing replacement goes I have done a number of wheel bearing on older 4x4 Scouts, Jeeps etc. Seems like the replacement would be the same other that the hubs are different on superdutys that older 4x4's.
