I am experiencing a similar problem with my 92 300E 114k miles. I get a rattle like noise on my left front suspension. Had it aligned at 110k by an indie MB shop and currently tires are wearing OK. Just replaced my front shocks with Bilstein Comforts. Its been suggested that I my problem maybe "control arm bushings". It $ound$ like its a $hop diagnostic trip to find the problem and have it repaired. I may not have the special tools to make it a DIY.
