The bolts on my from the factory were stripped thus it rattled. It seats into the frame. You can't miss it. So I bought a new bolt with a locking washer and it's gone now..

There is a vertical inner panel on the passenger side of the trunk. If you carefully pull the side panel black button out (this is just below a round upraised bump on the side panel) and pull the panel away from the side you will see a bolt (where the raised bump was) and on the inside of the vertical metal where this bolt goes through it holds a bracket with what looks like a small round speaker approx 2 to 3" diameter and has an electrical wire on the bottom. Hit the metal panel and you will see that this bracket and speaker?? vibrates and rattles like crazy. What I did is cut some grey eggshell crate type foam and with small plastic ties attached the foam to this part between it and the metal panel it's bolted to. Once I bolted it back in, I took a larger plastic tie and secured it around the bottom of the part at the electrial connection through a small hole in the metal its bolted to and around the edge of the metal where I secured the tie to prevent this thing from vibrating and rattling when driving over rough roads. This seems to have eliminated the trunk or passenger side trunk noise. Another thing I did is line the bottom of the well under the spare tire with a piece of rubber backed carpet as the spare and jack tend to vibrate and make noises also.

It rarely is properly tightened and sometimes stripped out.
The nature of such a heavy item on the end of a metal strap
bolted with one fastener is silly. Vehicles without the alarm
system (another reason to buy a non-factory alarm equipped
vehicle) dont have the 'speaker' looking horn. I guess the posters
have not ever seen a horn and thinks its a speaker?
