08 G6 GT "wobble" at highway speeds
This is my first post here on the forums so I hope its in the right spot!
When I first bought my 6 I replaced both of the rear shocks and the car developed what I would call a "wobble".
The wheel stays straight, but any time I hit a bump or go over ~40MPH, it feels like someone is wrestling in the back seat.
The wobble is side-to-side and feels like a really heavy crosswind.
I replaced the tires around a year ago and have tried almost everything.
The shocks were replaced once again after one was thought to be stuck, and the problem seemed to get slightly better but it came back.
I have had the car aligned many times and had the suspension inspected at multiple shops and nothing is turning up.
Is this familiar to anyone else?
Thank you guys!
