I need to rebuild my front 44 before next weekend. -Is there a seal between the pumpkin housing and the axle tube? I don't see anything on all the parts diagrams I find, but I find it hard to beleive that there isn't. -Also can I replace the carrier bearings with out having to have the whole thing set up again? I figure if I have to take it out to install the lunch box locker, I should just do them. Any advice is greatly appreciated.
