Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.Google+

I think its the same issue? My car drives fine without any excessive sway or dip, but the Drivers Side front suspension makes a very noticeable "bumping" noise when driving over a rough road or a cobblestone driveway? I have an extended warranty and will be taking the car in to my local mechanic for diagnosis later today. A visual check of the car underneath showed nothing out of the ordinary or anything wearing funny?
The best way to bescribe this noise... The top of the strut tower, where its bolted into the inner wheel well is loose? This would cause the strut to "bounce" or "Vibrate" in the mounting hole???
I'll see if I can re-post after the mechanic checks it out!
Had to replace bushings on right front control arm lower and left control arm upper. Car was making cracking sounds when I turn the wheel to park. Dealer suggest I replace the control arms as well but I don't think a peice of steel could be worn out in only 13 years they are not stealing any extra money from me. Plz recall it if it's a malfunction that is happening on many S500 benz 2000. Thx

Thrust arm bushings and control arm bushing replaced and repaired along with front right strut total cost $1,950.00
Right front control arm rubber mount collapsed and grinding the front sub-frame. Service estimate is $2800, changing both arms and used sub-frame. This was identified while replacing ABC suspension problem and replacing the steering pump for $4,000. Identified a Mercedes Technical Service Bulletin #P_B_33.15/12d which suggests that Mercedes knows of this problem and should correct it at no charge. Two Mercedes dealers deny this. I need help.

Front bushings are cracked on both sides of the car for the front thrust arms. I am currently looking for a reasonable price to have them replaced.
