Hey everyone, I'm new to this site and searched every where for answers to some issues I'm having with an 04 GTP I bought last month. It only has 53,000 miles on it and it's like new. The headlights bounce while I'm driving, I noticed another thread on this but the suggestions on what to check for didn't help in my case. There is also a loud squeak in the back suspension while going over any kind of bumps. Is this common ? I tried the search at the top of the page with no luck. Any help would be appreciated.
