Bump steer
Hello all,
I have 2008 Lexus GS350 AWD with 122k miles on it.
I am reaching you guys again to address Bump steer issue. I really need your help.
I have changed the following part on both front sides:
1- Upper and lower control arms.
2- sway bar links
3- ball joints and bushings.
4- shocks with KYP brand.
I still have bump steer issue.
Is there anything else need to be fixed or changed to fix this issue?
thank you in advanced.

Common problem for these 3GS is the front lower rear control arm bushings. Its the big round ball bushings that hold the front lower control arms. If these wear and they are common for them to wear, they will allow the car to bump steer, especially over bouncy uneven roads.
Also the parts you replaced with were they all oem replacement or cheaper aftermarket? Actually the suspension on our cars are really good quality compared to many other car companies. im at 240k miles and still have some original suspension bits that are still good.

If you replaced all the suspension bits with oem and everything is installed correctly. Then I would look at the alignment, there are adjustments that you can do to help lower the bump steer. You can also play with tire psi in the front, maybe your front tire psi is too high
