With 90K miles, it's time to replace those damn control arm bushings. After doing some research in the archives, I'm convinced going with 750i bushings is the best bet, however, when I called the dealer to get a price on the bushings, they asked for the year. Does anyone have the answer or the part number for the 750i bushings. An independent said I should go with 850i bushings. Are they the same as the 750i bushings?
