So, initially I had grease running onto both my rear wheels. I checked my diff vent and it was rusted shut. Was able to free that up and blow thru it. So, I replaced the shoes and cleaned everything up and they started leaking again. At this point I decided to replace seals and bearings because I had a separate issue with a noise in the rear end. 7 hours later all is back together cleaned up and the noise is gone. Took the truck to work today and now my right rear is leaking again. Getting pretty tired of this. Any help is appreciated.
