sooo for the first time ever i had the pleasure of seeing my car on the road when im not driving it....my friend was driving and i pulled up next to him and he cranked up the subs and i swear all i could hear is metal smashing against each other underneath the car....

im probably going to take it to a auto repair and see if they can tighten up that **** and put some stuff to keep that **** from happening

has this happened to anyone else?

What side of the car did you pull up on?

You can take it to all the auto shops you want but it won'y help....ahh if only it was that easy.

You want to get rid of it, pick your self up some Dynamat, Hush Mat, Spectrum, ect, ect.
If you were on the passenger side of the car chances are it was the vent in the trunk you herd .
If you haven't done this yet, get some 2 way tape and put it on the back of your lic. plate

brickloaf

i could hear it from both sides, sounds like pipes are banging together

and what vent in the trunk?? it was coming from under the car, and i have dynamat behind my license p

I had a similar problem.
It was under the car where the spare tire well ends at the back it was bordered by some steel ...fins I guess would the best way to describe them. They box inthe spare tirel well.
The well was flexing and banging up against the fins or the other way around. Spray on sound deadner help alot but didn't totally get rid of it.

If you pull the carpet off the passenger side of the trunk you will see a black square shaped plastic and rubber piece along the bottom behind the tire. It is a vent to allow air to escape when you close the doors. I got rid of mine and covered it with Hush Mat and some window screen from Home depot.
I did however cover it right up with Hush Mat when I moved my battery there. I didn't want to take the chance of the battery getting wet.
Now my sunroof pops up a bit when I close the doors, no biggy. So you can cover it if you so please

brickloaf

i think I know what your talking about, its close to the passenger side brake light...? on the far right side of the car behind the carpet?

if thats what you were talking about I took the rubber piece out cuz it was slapping up against the plastic vent. if thats not what your talking about I already have my entire wheel well covered in damp pro

I will guarantee you it is your heat shield. Check it.

brickloaf

unfortunately I have no idea what that is, ill look in to some how-to threads to see if i can find out where its located and see what i can do from there

thanks!

Heat shield
Its a good possiblity.
Its under the car between the exhaust and the car
The always come loose on every car.
If you try to fix it make sure the car has not been on for a while, the exhaust tends to hot and there is little room betwwen the pipe and the shield

brickloaf

is it towards the rear of the car by the end of the exhaust pipe, or is it far enough under that ill need to get the car jacked up

G85 SS

Yea, you will know what we are talking about if it is loose. On mine both of the rear rivets popped loose so I ghettofied it with some screws. I still get a teeny tiny bit of rattle but nothing like how it was. I am contemplating putting some rubber groments between the heat shield and undercarriage of the car. It's going to be towards the rear of the vehicle. Just follow the exhaust and you will see this aluminum looking shield thing. that is what comes loose.

brickloaf

will do! i have a LT btw if that matters?

G85 SS

Newp, still has the same shield.

yea its probably the heat shield becasue mine rattle loose since i put my subs in my i just took it off.because it got real annoying.

brickloaf

yep! it was the heat shield, its basically in the middle of the car so I cant get to it, and even when i do get to it, i wont know how to stop the rattle anyways...

should i take it to a shop and see what they can do?

G85 SS

I just took a screw. I found one that was the same size as the hole so that way the threads would catch and secure the heat shield. I don't know what size screw it was that I used.

brickloaf

are you sure its cause a screw fell out? or could the subs just rattle the hell out of it even with all the screws?

G85 SS

I had mine on the lift a couple days ago changing my downpipe and I checked it again. Still as secure as it was when I put the screw in.

brickloaf

this would be alot easier if i had a lift =[

G85 SS

Jack the car up from the rear. Shouldn't be too difficult to do that. haha

brickloaf

is there any way you can jack up the whole rear end? besides the individual wheels

G85 SS

jack stands are your friend. Of those ramps you can drive up on.
