well we drove the crossfire up to asheville nc today to see the biltmore. Anyways as I was leaving the biltmore when I put the car in reverse and turned the wheel to backup there was a noise from the driver side front. Almost sounded like a groaning sound. I was only able to replicate the noise later that night when the car had sat for a couple hours and again I backed up and turned the wheel. Any ideas what I need to look for?
