| Sounds like what ive been waiting to hear, anything tricky or surprising i should be ready for or is it all a pretty straightforward removal and disassembly etc... ive read the axle shaft removal can be quite a hassle...

Yes, the C-clips on the axle shafts can be a pain but they should be alot easier if you already have the case split since you can push them out from the back side. Try not to use too much force or you may damage the carrier bearings. If those get damaged you'll be doing a rebuild on it after that.

The driver's side is the weak point on these differentials. Go under the diff and push up on the CV where in enters and see if it moves up and down. If it moves any significant amount then you're likely looking at a full rebuild (ie just replacing the axle seal won't stop it from leaking).

You're not the only one in that club.  One of the projects I need to tackle before camping season starts again.

| Mines leaking too. Right down the center where the case sections meet. I'm guessing I am out of luck as far as warranty goes due to the truck being at 50k miles
