Need the carrier bearings, also may need a shim kit to get the back lash at a close to correct setting . Then will need some posi lube. along with a quart or two of synthetic or approved 80/90 . There may be some instructionswith the purchase. Will need to move the ring gear from old to new carrier. Have fun........

I like Motive gears so I went with #MGR-GM12-373 (ring &pinion) and #MGR-R12RSKT (bearings/install kit) and 5 Lug Axels from Summit #SAG-PA5855
