Vibrations???

[rida125]

Ok so when my car bumps i get all sorts of different vibrating noises on the outside of the car, and i think they sound really bad.

So the whole point of this thread is to find all the different spots that other people have found that are vibrating when their set up is bumpin and what they did to make it not make so much exterior noise.

Thanks for any and all help.

license plate...always the license plate....


and sometimes the trunk lid itself

[heineck]

Yepp and the panel that holds the plate.

[rida125]

yeah i already took the plate holder piece off and great stuffed that, but i still get some mad vibrations. i am also missing the rubber trim piece from around a couple of the tails, and i also think my spoiler is vibrating some.

[Ttop191]

Great stuff??? as in the expanding polyurethane insulation?

Umm...last I checked that was for houses not cars.....

[rida125]

yeah that stuff, well it expands as a foam, and i dont know why it wouldnt work?

Its just........wrong........like using house paint on a car....

I guess duct tape should only be used on ventilation systems from now on. I never looked at it like that! :haha:

[heineck]

I just put dynamat behind the plate holder

[Alerojester]

this will sound kind of off the wall but the last system i did i used Rubberized undercoating in the whole trunk and pulled out the tails put dynomat behind that and anything else that would rattle.... it actually turned out pretty good still some but not as bad

Common misconception... duct tape is not for ducts!.. ;)

wrong? why? it works, and is hidden...


also.. do what hein-y said... put dampening mat behind the plate.

[MattismodderX]

for the panel that the plate is attached to where the metal meets the plastic, take off the screws behind it, pull it out- and put a strip of 3m double sided tape (ask Afugy which kind it is). it completely eliminated that rattle. once it bonds... it doesnt come apart haha. as far as the rest of the interior, im goin to pick up some Boom Mat spray today at summit racing. each can covers 20sq feet so ill be getting 3-4 @ 9.25 a piece. once i get the car ready to spray ill post a review thread on the progress and how it works

[heineck]

^looking forward to this

i've heard the sprays (while easy to use) are horrible in terms of dampening, compared to the mat... you gotta do like... 3-4 layers of the stuff.. which adds up quickly.

[Afugy]

I know right now my worst rattle is coming from the cover for the sunroof and the only thing I do right now is push it inside of its hole but thats because the windshield is flex good right now.

The trunk rattles; the plate even rubber washers will fix that; the place where the metal meets the plastic the 3m VHB tape is the best, you can find it at AutoZone; and for where the trunk lid comes up to the rear glass its the plastic right off of the glass that is making the sound so you only need to dampen that so you can use weather stripping. Don't use the weather stripping on the seal on the trunk!

ive heard this as well but at 9.25 per 20 sq feet im not too worried. i figure its gotta be better then what it is now. so fk it haha. i got 3 cans and im going to start tearing apart the back end of the car today. not to mention whilst i was enjoying my stay at summit racing i spotted VHT Nightshade. so the tails will be murdered as soon as its not 15 degrees outside

[rida125]

what exactly is that stuff, like how does it work, is it like a foam, or how does it work?

You must not have checked then lmao.

Go to any real audio show. Any loud mod/super mod vehicles you see will be filled with spray foam. The point isn't exactly "dampening", but more so to add mass and stop panels from moving. It does a damn good job of keeping sound inside, though.

Our van has over $300 worth of "great stuff spray foam" in it, and that is when it was on sale lol.

[AleroDrime]

this thread is blatant not searching but while were on the subject, what are yall doing to your rear veiw mirrors, not only does mine look straight down it makes a nasty rattle

[JunkProwler]

For the rear view all you can do is tighten the screws periodically.

which screws? lol

[JunkProwler]

If you have the mirror with map lights, idk. But on mine, theres some small screws that you can tighten.

I lied there's only one. If anyone knows how to make the mirror harder to move I'd also like to know. But I don't think there is.

I just installed two 12" Subs in a ported box in my trunk with a 400watt 2channel amp. WHOA I got some serious RATTLE going on the outside of my trunk.

The loudest of my noise is coming from the panel that has the ALERO logo on the back of the trunk, Just by using my index finger and pressing on the ALERO LOGO the loud rattle is gone 99% I will hire some kid wearing roller blades to hang-onto the back of my car with his finger pressed on the Alero logo I guess...

But really I do not think I have to apply DYNAMAT all over the trunk, just on the factory holes on he trunk, cover all the factory holes might do the twick

For the Middle of the trunk maye add some sort of junk where the back window meets the trunk, and some sort of sealer.,.,.,

whatcha think

[PappaSmurf]

Basscar,
Do some searching on "dynamat" and also "trunk rattle" on this site and then Bam, all your worries are over. LOL
I have dynamat in my trunk and also on the rear deck and have VERY minimal rattle.

We've gone over this be for. The "panel" can be fixed with http://www.uline.com/Grp_240/3M-VHB-Tapes, you can pick this stuff up at auto zone, http://www.uline.com/BL_6050/3M-4926-VHB-Acrylic-Foam-Tape. Just get the panel off where you can get the tape in. Don't remove the red stuff till you have the tape in place on the panel or the trunk lid, once that tape it on there its not coming off, EVER. Its been on my car for 5 years now and shows no sign of letting up.

The other rattle from the plastic trim piece that comes off the rear window and meets to the trunk lid can be fix with some thin foam.
