1954 Wagon..Hey folks! I am replacing the rear pinion seal as it was leaking on this Dana 44. Before I install it, is there anything else to replace or need to know other than torque it to 200-220ft lbs. Doesnt look like anything that I can see other than put it back together, wasnt sure if the big washer behind the seal was okay to reuse? I have no plans on bearing replacement now, just the seal. Asking because sometimes there are washers that should be replaced...Thanks!
