Front-end Noise

Oct 15, 2007 1 Replies

I have a 560SL that is making a strange noise whenever one changes directions, either forward to reverse or reverse to forward and applies the brakes. The noise is a loud clunk and almost makes you think you've hit something. If you keep moving in the same direction and apply the brakes again, there is no noise. Therefore, it is as though something is shifting positions as a result of the application of the brake with opposite wheel rotations. Most of the front-end parts of this car have been replaced, so its hard to figure what might be the cause. Has anyone seen this sort of problem before? Any suggestions on where to look?



Upper A frame bushings.

Raise the front end off the ground. Pull the key out of the ignition. Grab each front wheel and move it forward and back harshly. Watch the upper A frame where it connects to the sub-frame. Any movement? If yes, replace the bushings. Easy to do. No need to worry about the coil springs or upsetting the alignment.
