I am rebuilding the rearend because one of the outer seals was leaking and it got filled up with mud. i got the ring gear out and the outer bearing in the axle tube and the differential replaced along with the seals. I was wondering if the pinion gear has to come out of the front of the chunk or what. it looks like that is the only way, and if it does do you just pry the seal out and take it from there? thanks.
