I would install the gears with a new bearing kit and new axle seals. You should get a shim kit for setting up the ring and pinion. The master rebuild kits will come with a shim kit. I would use the Ford synthetic gear lube with 2 little containers of friction modifier for the limited slip differential. Another good gear lube choice would be Mobile 1 or Amsoil synthetic. I had 4000 miles on my S331 when I installed the 4.56 gears and we rebearing it.
