I agree with tfischer. Just say you are "hearing clunking sounds from the rear suspension when going over bumps". I also recommend you ask for the wheel alignment to be checked. Some dealers are doing this automatically when they change the bushings. I know from experience that minor alignment problems have a big effect on ride quality (i.e. residual vibration after small bumps).

Yea...my car was made after June '01, yet needed the bushings replaced, with a vastly improved ride. Remember to use 38psi. in the run-flat tires also for a more optimal ride.

While I'm not 100% sure on this, I'm about 90% sure that the "rear bushings clunk" issue was only on early 2002 models. I don't have access to the exact TSB (anyone got a TIS account and can look this up? (https://techinfo.toyota.com)) but, I'm pretty sure it's 2002 cars made prior to XXX date. Should be a non-issue for any 2003 and up car.

I have a 2006 and run flats. This is my first run flat low profiles. Ride is rough and bumpy. Does anyone else with newer model SC430 experience rough ride? I was told this was typical of run flats.

I've attached the TSB that I have regarding this issue. It's old but I believe is still applicable. This bulletin replaced the one mention in comment #8 above. Hope this helps.

I just saw there posts regarding the ride. When I test drove several SC 430 that was the first thing i noticed and was very surprised because the car doesn't have the german handling so i expected a totally luxury ride which it wasn't. I can take that in a SLK AMG because what it is but not in the Lexus. The ride seems so contrary to what the car is all about ?
