I don't mean the rear axle, but something in the rear of my car rattles over rough roads and it's driving me insane! It sounds like what you hear when someone has a lot of bass in their trunk and their trunk lid and license plate rattles. I laid in the trunk today with my wife driving down our dirt road and i'm starting to think the spoiler is making the vibration sound.

Any ideas? I might try to remove the spoiler to see, but I hear that's a pain in the ****!

Thats probably why. Make sure everything is secured. Mine rattle too, and thats because the clamps don't fit perfectly.

I have the Borla stinger cat-back. I found that by placing a blanket between the trunk liner and trunk floor, that this all but eliminated what I believe is a metal rattle due to the frequency of the mufflers resonation.

Well it's definately a rattle caused by the bumps in the road. It could be the mufflers rattling at the clamps. I've almost eliminated everything else outside the car. I even tried to tighten the spoiler, but was afraid to turn the nuts to much. I need to place something between the spare tire cover and metal because it's definately rubbing paint off.

I saw a post somewhere describing a similar rattle...it was the struts that hold the decklid open, they were loose. Have you checked them?

I removed them and test drove it, no dice. Removing the spare tire and jack seemed to make it worse.
