Reduce Trunk Rattle

I found something interesting the other day. I was able to greatly reduced my trunk rattle using cardboard. Sounds weird but it actually works. Just take some thick cardboard, like the ones that hold soda and fold it so it's about less than 1/2" thick. Then open up the trunk, and place a cardboard piece along the side and on top of the rubber lining. Then just shut the trunk with the cardboard piece wedged in. If it doesn't close then the cardboard is too thick. Finally add a small piece behind the license plate.

I know it sounds stupid, but it works. A cheap alternative to dynmat.

I'd figure you'll be replacing this periodically as you continue to crunch it and moister detriorates it. Good idea, don't get me wrong, but you might want to find something more long term. Dynmat is just too expensive but I bet a walk around Home Despot will find you something cheaper but more durable than cardboard.

Parts Express has some very cheap damping sheets. I can't testify to the quality though...

www.b-quiet.com this is the cheap alternative to dynomat and much more reliable than cardboard. I also posted it a few post down.

Spray insulation, just spray it between the two sheets of metal in the trunk lid and trim off the excess, and paint to match.....

some of the dampers barely even work. I tried out the dynamat and it was just a waste of money. I still got plenty of rattle, but when i switched to the cardboard, there was significant reduction in the rattle vs. the dynamat. To me the cardboard trick works fine enough, plus it's easily available mostly anywhere

if you are wedging the cardboard between the lid and body why don't you just adjust the latch in your trunk. loosen two bolts and move the latch down. adjust as necessary to get a good solid closure without it being too tight. that way you don't need to use cardboard which over time will destroy the rubber and you don't need to do any thing fancy when closing.

There's a cheap option for dynamat at Home Depot...

I believe it's called bich a' thane (sp?)
Black tar paper with a foil backing just like dynamat. It is used as a moisture barrier in construction. My buddy used it on his beater car to improve the sound quality and quiet the road noise. It worked as well as the dynamat on his nice car. It comes in rolls that are 1' wide. It's a ton cheaper than dynamat and it works great.

Ahhh, just found it,
Bituthene is the spelling. Make sure you get the foil backed stuff that applies like a sticker.

Good luck, and I take no responsibility for anyone getting stuck to this product, or it stuck to any place not intended...
