Hi All, need some help.

I have a rattle in my trunk, 2011 mustang gt. I can stick my head under the trunk lid and tap my finger around the speakers to duplicate the problem. It also happens when going on roads that are a ruff, that cause light vibrations in the car.

So what I want to do is remove the carpet above the speakers, under the rear window to inspect under that.

Has anyone else had this rattle? Also, can anyone tell me how to remove the carpet?

 

I had a rattle/tapping sound from around that area on the right side on my 2011 GT. It turned out to be the thing the seatbelt coils up into.

Pull out the seatbelt all the way and hold it pulled out tight while driving. If that sound stops then, that is it.

I fixed it by jamming some rubber in around the part. I had to fold down the rear seat and get my hand up into the hole on top. If you look into that hole and to the side you can see the seatbelt coil thing.

I hope this is it.

I have the same thing in mine. It drives me crazy driving with no music on. i will try the seatbelt thing and see if that is it. I hate that rattle.

 

I have the same issue of what I think is a rattle / squeek from the right side passenger door when going over a roughish road. However when I have had someone in the passenger seat to listen for it they say it's from the left side or even behind of us so I guess it is actually from behind.

I did see a while back someone posted pictures of their fix (seatbelt issue) but can't find the post - anyone know which post it was or any other suggestions as the rattle is driving me insane Thnx

 

I have a rattle everywhere, lol. I have the shaker 1000 and everything shakes and rattles.

Suuuuuucks.

 

I have some kind of rattle coming from the right rear when going over rough surfaces, but not bumps. I originally thought it might have to do with the bumper support, but seeing this thread, I might have to investigate the seatbelt and speaker area... Drives me nuts, especially as it is not there all the time, only on rough road surfaces.

Thanks for posting this...

 

I hate to bump an old thread, but I wanted to say that I have been dealing with a rattle for a long time now coming from the driver's side rear seat area. It turned out to be the seat belt tensioner as described above.

For the longest time I thought it was one of the body clips for the C-pillar trim panel, but thanks to some searching I found this thread and checked the tensioner. Sure enough that was causing the rattle. I have (temporarily) fixed it by shoving a microfiber towel around the tensioner. Rattle is gone. Since it's completely tucked out of sight I might just leave it like this, or maybe later in the Spring I'll come up with something a little fancier.

Anyways, it was driving me nuts. Now it's not.
