I have a 2003 GS 430 with around 116k miles and in the last year the car has gradually lost its smooth ride. Its feels almost like a vibration coming from under the car when driving at higher speeds, or around curves. The auto shop said that new struts could fix this.

Has anyone had this problem with their GS? What is the best way to make the car drive smoother again as it did with less miles?

Thanks for all advice!

motor mounts.

easiest way to check this is to pop your hood, have someone stand outside and look at the motor. slap the car into drive while holding the brake, then while still holding the brake hit the gas for a few secs -- see if your motor shifts or moves.....

I have the exact same problem, Have new Michelin tires, new rotors and brakes, new all four Lexus struts and all four Lexus Springs.

i went to dealer : they responded back saying i have front brake and rotor warped (give me a break) i told them there are new rotor and brakes in there, installed just 2 wks ago. I walked off trying not to have any argument with them. --- That is not possible those new rotors or brake be that bad in 2 wks.

Changed Factory rims to custom rims - No solution.
Performed regular and hi speed balancing on HUNTER GSP9700 series - No solution

Everytime i go to a shop for this problem - every one has a new story.

My Observation: when car was lifted on hydraulic and put in drive (VSC turned off) found rear passenger side wheel hopping tremendously which causes vibration underneath the vehicle, i dont know what the issue is.

I have been looking online but to this day i dont have any resolution. This is the worst car i ever had.

I've found that if the wheels are not torqued correctly I get vibration at speed.
Just one thing that is easy to check.
