Mine has the exact problem you have and currently unresolved and wearing me out....Just received my car two days ago (shipped via carrier to my home) and have just 100 miles on it. The right front when going over small road cracks at low speed sounds like a bad ball joint in my truck. Has anyone had a problem? Thanks in advance!
I wish mine was the swaybar, but they removed mine and drove it without the swaybar, and it still did it. I think it is strut mounts, but who knows. I am going to do my best to ignore it....Hey guys I just signed up so this is my first post and hoping to be able to help even thoe I do not own a real GT500 I do have a 2007 GT and have had this noise that made me look at every tree as a possible target...JK...it is your swaybar it has a small amount of play so my solution to it was adjustable swaybar links and have a link on one side pull and the other push so it can tighten the swaybar as much as it could (it did it for me)
