Just like the topic says, whenever I turn my car (the harder the turn, the louder it is) I hear a "crunching" noise from the rear part of the car. I checked out the spare tire in the trunk and the jack in the compartment but both were secure. Also, I had my rear window broken by a baseball bat and had it replaced. I definitely know that it's not glass moving around because I cleaned up every piece. The install guy did a great job with everything and there have been no leaks in rain or snow, which should mean everything is tight. I also checked the rear seatbelt adjusters on the B pillar (I think that's the correct term) but those weren't loose either. It's making me mad. I'm just looking for some suggestions or if anyone else has had this problem. Thank you!
