| as far as i know, it can't be done. Well not properly anyway. I know a guy that has tried and failed and a friend of mine tried to do it by taking it to a machine shop to have it done. It was close, but unbalenced and cuase bad vibrations. Your best bet is to save your pennies and get a whole new driveshaft

Has anyone had any luck changing U-Joints on a BMW E30 driveshaft?
