I have a 2002 CLK430 with 12000 miles. At low speed the wheel will shake on road ruts or just rough terrain. I have sent the car twice to the local MB dealer for this problem. Both times I am told that they cannot find any problems. I bought this car 1-year old with 3200 miles. It did not have this problem then. The problem started around 9200 miles. The tires have normal wear for the Sport Pilots. Has anyone ever had this problem? Any suggestions?
