“I first noticed this last year when I went to ny for thanksgiving. Everytime I turned to the left my car would shimmy and shake, I was told I was missing a weight on my rim so I didn't think anything of it. As the year went on it would only happen every so often and at times would do it at all. It started to act up again but wouldn't stop and even stepping on my brakes would cause it. I brought it to a local shop and they advised that my ball joints were shot and to bring it to a dealer. …”
NHTSA complaint #10428290, filed 2011-10, 86,000 miles“I have a 2008 Pontiac G8 gt. The issue is the front suspension. Around 43,000 miles the car started getting very bad sounds and vibrations coming from the front of the car. When applying the brake under certain speeds and conditions the car will go into a violent shake. When driving straight I'm fine but if I head into any kind of a curve in the road the steering wheel is shaking badly and the whole car shutters. I'm out of factory warranty so they couldn't do anything for me. …”

The tech told me both lower ball joints were shot and they would overnight the parts. I told him there was a recall on ball joints but my VIN was not included. I also brought a copy of the TSB for the ball joints and told him I wanted all 4 control arms, not just the 2 lower ones. The exact wording of the TSB is ... And found to have one or more of the rubber boots improperly sealing should have all 4 front control arms replaced. …”

I came to find out from a garage that the lf control arm needs to be replaced. You can actually wiggle the tire from left to right when it is up on a jack. Two years ago, the right side had the same problem and was replaced.”

Gm hasn't issued a recall for this issue and its a safety issue. They released 4 revised control arms with better ball joints that needs replacing on all the G8.
