On my 240D, and a friend's 300D, I could see that the upper control-arm inner bushings were shot. In my case they were so bad, the control arms were rubbing on the inner wheel housings, but because of the tension applied by the stabilizer bar bolted to the upper arms, I couldn't actually tell they were loose by shaking the wheels or suspension. My friend's upper control arm went in easily, but I had to cobble up a special tool to pull on the stabilizer bar, and allow the control arm pivot-bolts to line up with their holes in the inner fender.

Happy Motoring, Mark
