I remember you saying you had the rear upper control arms on order,did you ever change them ? If so did it fix the problem ?

i can tell yall from my experience that this "swaying", "shaking", and "side to side" motion is from having bad front lower control arm bushings... that would be the #2 arm or "caster arm", "strut rod". i have had all these problems with my gs300. i am 95% sure this would fix the problems your having. you can get the arm for about 120 a piece or buy the bushings for both sides on ebay for 70 shipped.

I would like to see the final solution for this problem. I'm having the same issue, i though it was my tires, then I balanced the wheels too and its still shaking at high speeds. I was told that maybe my rotors need to be turned, because I noticed the symptom started after I slamed on my brakes hard, at a trafic light camera intersection. Sucks that we all have this issue and no remedy yet. Good luck to us all! I'm definately keeping a look out for the solution to our problem.

Mine's been vibrating a lot lately, my steering wheel used to sway everytime I hit a bump or heavily braked, my control arms were bad, well now when I slow down the car shakes but no steering wheel movement, i'm almost 85 percent sure my rotors are super warped, but the car also vibrates a lot at high speeds (70-90) I saw one of my sway bar links in the front is bent and already ordered both of them, together with lower ball joints and inner tie rods

I hope we find a solution soon though because this can be a very annoying issue

Well I guess no one saw my post where I said it was the lower control arm #2 bushing (caster arm) (strut rod)....... I did this months ago and haven't had the shakes since. I think I actually made a post about it. It's easy to do in a day with a floor jack two jackstands and a tool kit, you can get the bushings off eBay. $70 for two bushings.

Just a hunch, put your car on a lift and set the speed with someone or a pedal depresser and watch the axel in at the point where it goes into the differential. I am wondering if you have play where the axels go into the pumpkin. This could be your bumping that you hear/feel. Let me know what you find..and dont do it on the floor on bricks!!! BE SAFE!

I know this thread is a little old but I am having these problems as well and I'm looking to buy these specific parts USMCgs3. Where did you purchase your caster arm and bushings from if you dont mind me asking?

Thanks man!
