BMW's don't have u joints....what are you going to replace?
HMMMMM idk cuz theres one at the end of the drive shaft near the rear and thats what ive been told is the problem and ive order the part.
I'm curiously waiting for the results also, since there is no u-joint on Bimmers. There are flex discs or center support bearing. What part# did you order?
