I recently bought an 83 300d (123). There seems to be a problem with the suspension. On the 10 miles trip home with it, it was making a slight grinding noise in the front end drivers side. It has become pronouncably worse and I'm almost afraid to drive it now. It's constant sound now. I repacked the wheel bearings and the brakes look fine. There doesn't seem to be anything loose. The wheels do lean in on top, more than what looks normal. Before purchase, the car had flat tires for about 2 yrs (only on the right side and the tires have no more than 1000 miles on it). Could this have done damage to something? Any input would be greatly appreciated. Thanks!
