I think I may have the same problem as you. I noticed recently that when I turn left or just hold my steering wheel a bit left of center I hear a clicking/rubbing sound from the front right wheel. At first I thought it might be the slotted rotors, but it only does it when turning one way. I guess I need to check the CV boots today.
Is replacing the axle a straight forward job, or does it require special tools and such?
