This is an undertaking necessitated by a specialty shop with the correct gauges and experience. While not very expensive (I would guess about $200 labor) it is a job that you want the mechanics to have some experience at setting up rear ends (cars', not peoples') and the correct tools (the gears must be set up at very specific angles and tolerances...it's not a"bolt on" job. There may be some more folks on the forum who can give you more precise and accurate feedback. Hope that helps. Mark
