Well, I took off my rear driveshaft as one of the steps in dropping the transfer case, and now I noticed a possible issue with the rear diff.

The pinion yoke has a little bit of in and out play-- that is if I pull and push on it, it will move in and out a very small amount. Does this mean that the crush sleeve is shot and it's lost bearing preload or is this normal?

I've read about rear axels blowing up on people and thought that maybe this is an early sign. Should take off the pinion yoke and replace the crush sleeve?

Thanks! I replaced the crush sleeve and torqued to about 22 inch pounds pre-load with a new seal. The gears didn't seem to be in bad shape, and the in-out movement is gone, but now the yoke seems to rotate very slightly to the left or right before it "catches" and starts to turn the axel. It's really only a tiny bit, so again, I'm not sure if that's normal. Is there a tolerance for that kind of motion, or should there be none noticeable?

I guess I should add that I haven't really noticed any strange noises or other symptoms from the rear driveline. Everything is together now and it seems to be working fine. I just don't want to end up with greater damage down the road if I can fix it now.

I haven't really done anything with differentials other than replacing a bad pinion seal and now the crush sleeve, so beyond that I don't really know what I should be looking for-- I'd really like to learn though, so your advice is very much appreciated.
