I cleaned the grease out since I had all torn boots, and I wheeled with em that way at uwharrie. I am sure there was dirt and whatnot. The solvent based parts cleaner is free to use on baseGrease is cheap, CVs are not.
I did grind all the welds flat on the inside face. Hopefully its actually flat and gets a good seal. Isn't the axle seal the actual fluid sealing surface? Maybe I will put some RTV along the seating surface as well just in case the axle seal leaks.
I just borrowed Halo Reach from a friend at work,its very hard to decide to work on the truck right now...
