I know this is an old post but here is some new info. Larry just removed, rebuilt and reinstalled my differential last week (Aug 2010). He bead blasted and painted everything, used all new parts including u-joints, bolts, nuts, washers, etc. Also installed new adjustable struts so rear camber can be easily set. He did all this with several trips to my house in Mandarin. Yes, a bit slow but very professional work and reasonable.
