what are the parts of a sedan cobalt that rattle the most? i have already fixed the rear deck but i have a few more rattles and i just cant find were they are?? anyone have any idea what parts rattle the most?

 

howd you fix the rear deck? which part of the rear deck did you get?

 

The one I'm battling right now is from the sunroof shade, if I have the roof amnd the shade all the way back the handle on the shade rattles against the frame of the sunroof.

Have you had to deal with the air vent in the trunk yet?
You might not be able to hear it from inside but trust me you can hear it outside, turn up your stereo and walk around to the passenger side rear quarter panel.

 

lol spun i just had issues with said vent as well. nothing my crazyness couldnt fix

 

i fixed every rattle in my car. I used like 125 sq feet of dynamat, but nothing rattles. i shut off my speakers and just ran thesub to hear if any rattles. nope.
the rear deck obviously rattles like crazy, i dynamated the top and bottom of that, the entire trunk, put two more screws in the license plate, dynamated the doors, and the roof around the sun roof button.

 

THAT MIGHT BE THE ONE I AM HEARING!!! there is one around my head on the passengers side and its pissing my off!

 

yeah that was what rattled the most. it never rattled that bad until i dynamated everything. i guess the vibrations had no where else to go so they shot up the roof. just added dynamat extreme all around the button etc. and its all good now.

do what i did turn off your speakers and just let the bass hit, then you can hear very clearly where the rattles are coming from, then tackle them from there.

BTW: although dynamat is expensive it works wonders.

 

Rear view mirror......badly. Dunno how to fix it either other than turning the bass down

 

take that **** off it does no good when you cant see out of it lol
i keep mine in my glove box for when i need it *cough cops*

 

The thing about sound in a car is it bounces around so sounds might not always seem to be coming from where they actually are.. With the music up push hard against the headliner between the button and the windshield, if this fixes it than thats your problem, if not then keep searching.

Just some words of advice, there are always going to be rattles, as soon as you fix one another one pops up, just learn to tell which ones are fixable and which ones are not

Emp- I just riped mine right out and put dynamat on both sides, it fixed the rattle, but now when I close my door the sunroof pops up a quarter inch then goes back down. If you cover it up completely make sure you poke holes in it, Its purpose is to allow air to escape when closing the doors, I'm sure you already knew that but just incase.

 

use a star screwdriver and tighten it... thats all you have to do..

 

x2 throw some second skin up there too to get rid of any problems because if you dont you will need to re tighten that bolt every few months

 

ive retightened once... just do it really really tight...

 

ya i know but i think i might have been getting a water leak from ther (not sure how but really the only explanation i could think of.... The trunk is eventually getting sealed anyway so its purpose would have been short lived. Peeps are just going to have to handle all the pressure of the door closing

 

Again, I'm sure you know this but just in case... On either side of the trunk there are two black tubes running down, these are water run offs for the sun roof, if one of your tubes came loose at the bottom, where the elbow connection is ( I think thats right where your battery is) it would give the apperance of a leak. Once again I'm sure you have already thought of this but I'm throwing it out there anyway.

 

squeek fan when on setting 1

 

nah cant be it because i dont have a sunroof.

Reason why im so baffled is because there was a bit of water everywhere and i can pinpoint most of where it came from... The batt tray for the kinetics in the wheel well had a very minor leak im thinking but i know for sure there was water coming in from both the screws that mount the NGT batt and the sub box. Some how im not sure how but that box's vibrations was unsrewing those L brackets. I just re tighened them and put some damp pro/ spectrum to seal it all up. Then i did quite a bit of damp pro and spectrum around the NGT tray to seal that up BUT at one point it was wet on top of the NGT battery... It wasn't wet anywhere else on top or anywhere i could find but on the top of the batt. So just foamed that opening and covered it in damp pro and sealed it all up.
