I have a 91 190e. It has developed a vibration from approx 40-70mph. The vibration gets much worse while light to moderate braking. During heavy braking the vibration will stop(most of the time). I have rotated and changed the tires without much luck. Most suspension components have been checked replaced. The vehicle has been aligned, but the vibration is still there and the inside of the front left tire wears dramatically faster than the any of the other 3. The only thing I can think of that has not been replaced are the front control arm bushings. Could these cause this type of vibration and wear?
