      This may be a shot in the dark but, I have a 2006 Grand Prix that I am experiencing front end suspension noise and I am hoping someone may be able to shine some light on my issue. My grand Prix is the base model sedan with the 3.8L Series III non-supercharged. The noise is worse when it’s cooler outside; 50 degrees or colder. When you start out from a stop and start to accelerate I get a crunching noise from the front end. It sounds like it is a lower suspension noise coming from something attached to the sub frame. I also get a very slight clunking noise when going over bumpy pavement or riding on rough surfaces. My car only has 58,500 miles on it. I haven’t been driving it much in the past two years since I have been using my truck more. I just had a state inspection at the dealership in November and they didn’t notice anything. Everything seams tight when I looked at the front end in November. I plan to jack up the front end tomorrow after work and tug on some components. I was thinking strut mounts, control arm bushings or sway bar links or bushings. I couldn’t imagine it being an engine mount since I have hardly driven it since inspection and with it having such low miles. I am not getting hard shifts or engine vibration through the body that I normally have experienced with other bad engine mounts. Is there anyone out there that is familiar with these front ends that may know of a common failure they could recommend? Thanks in advance!

          Previous generation Grand Prix’s were known to have weak ball joints. I would look at ball joints, outer tie rod, and potentially the upper strut bearings.
