I just bought a 91 300E and am very happy. I notice when driving, especially at lower sppeds, when I hit a small bump, I feel a slight clunk in the steering wheel. Nothing major, but it is there. COuld this be the tie rods? Ball joints? Steering damper? Or something more? Also, how hard is it to change this for someone with moderate mechanical skills( I change my own brakes, radiators, belts, hoses, etc). Any info would be greatly appreciated as always.
