I just turned 200,000 miles on my 2004 GX470. I am the original owner. I had a very good experience with my GX. Besides the normal maintenance jobs (brakes, tires, spark pluds, belt) I have not had any other major repairs. However, the last few months, the car waves sideways when I hit a bump on the highways. It sways sideways. I checked the sway bars and the appear to be fine. Has anyone else experienced this and what did you have to change to stop this wavey ride? I appreciate any help. Thanks.

 

Mine just started doing that. I'm suspecting lower control arm bushings or tire rod ends at this point. Taking mine in on Monday to find out for sure.

 

I would be interested in what you find out about your suspension. Thanks Mark

 

Nothing was found, except a slight alignment issue.
