Do a search for threads about lower control arms. Sounds like that may be the issue.I have a 2009 G8 GT and I'm hearing a clunking sound in my steering usually when I'm backing out of my driveway and pulling away. The steering doesn't seem loose or sloppy but the clunking is driving me crazy. I'm thinking it's my intermittent steering shaft but I'm not positive. Has any one else experienced this issue?
