Rear differential pinion seal
 

Ok hive mind,
Walked out to the Cherokee today and she showed me a gift. A leaking rear differential. Looks like it is dripping from the base of the cover and the front of the differential where the yoke is wet as well. So I know I am changing the fluid and resealing the things but looking in how to change the pinion seal there are a million different opinions and methods. I got a D44 with a Detroit locker and would like to do this the right way, any pointers?
