All I do when I take apart the diff is take all parts out, clean them with either namptha or motor spray, then coat each ball a little bit with grease. Install the balls in the gear, and put a layer or grease over the balls on each side. Then do a layer on the thrust on each side. Remember to clean off the thrust bearing as once I put too much AE black greas eon the thrust, my diff was gritty, and when I opeaned it, it was ALL black! You flip the rings if they look worn, but then you have to rebreak them in, [see bfastrc thread for how to break in a diff].
