hey guys, im hoping u can help me out. ive had my crossfire for a couple of weeks now. since i got it ive noticed a rattle in the back when i hit bumps. when i called the crossfire line, they told me to take it in for service. i took it in and theyre telling me it is normal. its because the suspension is so tight. they told me others have complained about this too. has anyone else noticed this??????????????
