Rep Power: 301

For the longest time, my trunk springs would resonate violently when my sub hit certain low frequencies. It sounded like two pieces of metal clanging against each other. Originally I thought it was the rear shelf causing the ruckus because that's what a lot of people have trouble with. In the end, I narrowed it down to the springs and applied sound deadening to them. It worked like a charm. The only trunk rattles I have left are the ones caused by the trunk vent and the trunk latch but those are barely noticeable compared to the rattling caused by the trunk springs.

Anyways, I hope this post will be of help to other people that may have the same problem.

or you can remove the springs altogether and do the trunk shock diy

yups, but i didn't bother because it's more work than i feel like doing...

all i did was wrap sound deadening material around the springs that hold up the trunk lid. it was a simple, cheap, and very effective solution to the problem i had.

note that not everyone will have trunk spring rattle though. if you're not experiencing rattling from the trunk springs, you probably don't need to sound deaden it.

lots of people seem to complain about the rear shelf rubbing against the rear window. my car doesn't have the annoying rattle from there so i didn't bother trying to fix a nonexistent problem

btw, to tell whether if your rattle is caused by the trunk springs, sit in the back of the car w/ the seatback folded down. turn up the subwoofers, and when you hear the rattling, grab the springs w/ your hands to stop the rattling. if the rattling doesn't stop, the trunk springs aren't the problem.

note that the trunk spring rattle doesn't happen with the trunk lip flip open.

you can also pound on the deck lid from inside and see if you hear a springy type sound lol.

i've tried it but it didn't work very well because the trunk spring rattle happened only at certain resonant frequencies...

i guess i should throw in an extra hint. it you want the sound deadening install to look good, it may be easier to wrap the springs if you remove the springs first. that's what i did because i had the honda trunk spring removal tool.

note i also used a super thin deadening material because for wrapping a small diameter rod, it was easier to wrap a few layers around the rod rather than one thick layer. don't ask where i got the thin stuff. i got it for free and don't know where to get more.

Slug, why didn't you throw them in the garbage while you had them out and replace them with struts? Opening the trunk is easier and rattle isn't a problem either.

haha, i would but there are so many other things i want to get done on my car before trunk springs becomes a priority...i actually had the shock kit but sold it after letting it sit around for more than a year.

my fix was cheap because i got the sound deadening for free...it was also easy because i had the honda trunk spring removal tool lying around
