When I had my gears put in (at like 160k miles) all I had was synthetic gear oil, and the gear kit from Ford. It had the proper shims, pinion nut, etc.. The only thing I would suggest is have a good look at the differential, make sure its in good order, otherwise get it rebuilt. In CDN$ I had my gears and subframes installed for $500 (including the price of buying them).
