Mark, I mentioned in my post above that I tore mine all apart before I ordered the parts. My carrier bearings and races, axle bearings etc, all happened to be in great shape. I only ordered the ring and pinion, shims, axle seals, and the housing gaskets.
Fred is right, you will have all the parts in the installation kit in your hand during the swap. I would only want to do the job once if it were me..
A friend of mine in the parts business priced all the items in the installation kit and found that he could not buy them any cheaper than Patrick's.
