Hello I'm new to the Forum and I have a 2001 S430 recently got new tires and a wheel alignment but for some reason when I drive I'm still feeling some vibration. I have gone to the dealer and they say nothing's wrong and they think it's the tires. I went back to where I purchased the tires (michelins)which was Sams tires and they re-balanced them. That worked for a minute but now it's back vibrating mainly when on the expressway traveling over 60 mph. Any adice would be appreciated, I'm tired of going back and forth.
Thanks.

 

the rims could be bent....or you could have worn out suspension parts too.

 

They confirmed it wasn't the rims however they did say something about the lower control arm bushings being worn and needing replacing, do you think that could cause the vibrating

 

yeah the lower control arm bushings did have issues on earlier S classes. the bushing breaks apart then the actual control arms start to rub against the subframe and is dangerous. it could be bushings yes.
