Rear end leaking grease around the seal on the differential seal
I have grease leaking on the rearend on the differential seal. I've never opened a differential bell before, I was wondering what I need to know prior to opening the bell and replacing the gasket. What do I need to be aware of prior to opening and is there anything I need to be aware to ensure I get back together correctly. Any and all assistance is appreciated.

You HAVE to measure the pinion preload prior to removing the pinion nut (assuming it’s a 9 inch with a crush sleeve). When re installing the nut, you should torque it in small increments until you’re back at the previously measured pre load. Not a hard job; but, if you don’t do it right you could destroy the diff. Easiest way to do this is by removing the pinion housing; it’s only 5 or 6 bolts. No need to remove the axle shafts; but, you’ll need new diff fluid, a pinion housing o ring, and a pinion seal.
this should give you an idea of the process:
