Buzz after AAM Short Tail install

scope22

ok, then its somewhere else....you should read that entire thread, different peeps have different rattles...some suggest putting a penny in those holes where the rubber stumps go from your hatch to tighten it

I am 98% sure it's the electrical plug to the 3rd brake light. That thing is not tightened down at all, and it's between the two metal panels of the inner and outer body of the hatch, so you can't get to it to tighten it down. That's where my foam idea is coming in.

Hmm looks like I have a decent amount of things to try, mine is the touring/sport so thurs I'm gonna get up early and start one by one trying to isolate my rattle. Where can I get the dynomat stuff or whatever it's called?

To anyone interested, a weird thing happened yesterday morning. As I was taking my car in to get my two rear tires changed, I did the head liner check on the way in. In my case, the headliner wasn't the culprit.

The weird part is that after I replaced my rear tires the buzz was nearly gone! The tires that were on there previously were stock RE050As, but whoever had the car before me sprung for the run-flats. My right rear tire was WAY low, like, 1/32 low. Since the buzz seemed to come from the rear right, I wonder if the harmonic resonance of the tire caused it at certain tire rpms, especially since the run-flats have such stiff sidewalls. My new tires are not run-flats, so softer sidewalls (and holy Moses, what a difference in ride comfort).

My drive home was in a bit of traffic, so I couldn't really give it a full test. I'll keep researching over the next couple days.

Any thoughts? Any similar experiences?
