Hi there, I've had my 91' 740 wagon for a year now and am trying to find a vibration on the left front wheel only when I brake. I don't feel it only in the steering or the brake pedal but the whole front end. I replaced the rotors and still notice more brake dust on that wheel. I also change ball joints and control arm stay cone bushings. Should I replace the rear control arm stay bushing as well - if so how do I press them in? could it be a bad shock?

Thanks in advance
Alan

Since it is happening only when braking. Are the rotors new? Or were they turned. Sometimes it takes alot of grinding to get the warpage out of the rotors. I just went ahead and put new on mine. Also make sure you torque the wheels down the same. Also in a star pattern. Putting on with a impact wrench can mess those types of rotors up.

The rotors are new and didnt' make a difference at all.

Have you checked wheel bearing?

How do I check it that? do I take the wheel off?

Jack the wheel up. Grab the tire at 12 and 6. Pull & push. See if any play. Do the same at 3 & 9. This will also move the steering somewhat. You should be able to tell the difference.
