I have a complaint about my 300SL. There is entirely too much road feel transmitted to the steering wheel. I think I can tell when I run over a stone!
I have replaced both front shocks with their mounts and the steering damper. The wheel bearings and steering linkage are tight with no play to speak of. All four tires were recently balanced at the dealer.
Getting to my main point, I went by the dealer today with the above complaint. He suggested the front control arm bushings may be shot. According to him it is not uncommon for these to require replacement on a car with 115K miles. And he added that bad bushings can visually appear just great from the outside.
And I asked about the lower ball joints. He said these require replacement far less frequently.
