Okay, so I'm still getting that rattling noise in the rear. I can't see it being my suspension because my KW V2's are only 2 months old but it's still a possibility. I checked everything under the car and in the car from loose stuff in the trunk, battery, fuse box, trunk latch, rear seats, exhaust, bumper valence and I can't figure out what the rattle is. It only happens when I hit bumps with the right rear. Here's a video for a better idea:
Hopefully you guys can get an idea from this that might help me out.
Thanks!
