Rattles - one in particular
2008 Cobalt SS/TC....
This just MIGHT be the worst rattling car I've ever owned. I don't know, but it's right up there. Holy *****...
I located one noise. The front sway bar end links.
There's a noise in the back passenger side. At least I'm pretty sure it's that side of the car but definitely the back. I've been looking for weeks trying to figure what it is.
On the outside - It's loud as ****. Sounds like a heat shield or something. Sounds like metal but it's caused by bumps in the road. For example if I'm going like 5 mph over the gravel driveway it's loud as hell. But I hear at speeds of like 30-35 too and in-between.
On the inside - Sounds muffled. Like a gentle clunking. Like someone on the outside just tapping with a rubber mallet. But still super annoying.
Rear of the car.... like I said.
Any thoughts or known issues that I'm missing?
Overall the thing rattles like a bitch. The rear deck rattles like hell, the front dash, the doors, the seats. It's insane. Thank goodness for the stereo but when I want to talk to my passenger it suuuuuuuuuuuuuuucks. I'd like to just rip the bitch apart and sound deaden EVERYTHING. I don't even give a **** about the added weight. If I had the money...
Thanks for any help.

The only mod I have that could POSSIBLY be related is a catted downpipe from ZZP. I'm not lowered.
Also, warranty is out of the question. I just crossed 50K miles yesterday. lol The rattles really came on strong 40-45K miles... so uh.... good luck to you all.
Anyway, thanks for the suggestions. I might check into the exhaust. I'm doubtful but ZZP does put a little weird curved tube for the O2 bung.

My 09 SS just hit 2k and it has bad wind noises ever since day one. It has a sunroof and it is very loud when closed as well as a noise coming from the drivers door. I am very unhappy with that. Took it in for warranty at 600 miles and they said it was "normal" for a Cobalt.
Mine has some light rattles as well as sometimes can hear strut plates creek when turning steering wheel during parking lot manuvers.
This is the loudest car I have ever owned. My last daily driver was a Grand Prix GT that I bought brand new and in ten years put 200k on it. It was never as loud as this car is.

My sub $25K Acura RSX-S? FAAAAAAAR less rattles. Almost zero.
My sub $25K '95 Grand Am before that? Perhaps the same or slightly less. But it was at 155K miles and 10 years old also.
...And I could go on. This car is 2 years old. I kind of figured they might have made progress.

I put double sided stick tape on all of those decklid clips on my car to stop it from rattling.

The main rattle that this thread was about remains a mystery at the moment. I may just take everything in the trunk out and see if I find something loose.
