That will come with all new bearings and races, maybe a shim assortment for the carrier and some gear marking paste to check the contact pattern of the teeth. You'll have to press the bearing off your old pinion gear to get the shim I mentioned earlier. The only thing missing from a master install kit will be axle seals and new axle bearings. Those outer axle bearings are pricey and not to fun to install. It pretty much takes a slide hammer you pull those out and I wouldn't mess with replacing them unless you see damage on the bearings or the axles. I would suggest buying new axle end seals and replacing those while you're at it, you don't want to go back in there for a few dollars worth of leaking seals. If you need help getting the pinion bearing off, let me know, I can press it off for you and press it back onto the new one if you want to drive up here to the Denton/Corinth area, assuming you are going to do the work yourself.
