Good luck getting the ABS sensors out, I broke both sides when I did mine. Since then I've learned to soak them in WD-40 before getting the screwdrive/hammer out. Mine wouldn't budge though. If you manage, they come out from behind as one piece. Good luck! I hope you went with 4.10's, I almost wish I'd of gotten 4.30's now. The difference in very noticable as I went from 2.73's, but not as much as I thought.
I would pick up a Pinion seal and Axle seals to...might as well change them while you have it open...got RTV for the dif cover??
Should really do the Trak-Loc rebuild since the difs coming out if its still the original set-up..
