my 2002 E53 Manual trans was leaking oil at a rate of 1 qt per 500 miles. It did not smell but the bottom was getting a good coating of oil. I figured I might as well see what else I could replace whilst doing the oil pan gasket change. It was not as bad as we thought. With 237K miles on the clock we were expecting some bolts and nuts to give us a fight. So here is what was replaced during this process. Front controls arms, outer tie rod ends, cleaned, scraped and repainted the sub frame, oil pan gasket, oil sending unit, rotors, pads and e brake shoes all around, backer plates on the rear, valve cover gasket, and installed bluetooth, all drivetrain fluids changed. I could not have done it without the help of one of my best friends. as soon as I can figure out how to put pictures in posts I will.
