My hatch has rattled a little since day one... now something on my dash is vibrating. This kinda stuff sucks, but honestly I've owned 2 Nissan Z cars, a Honda Accord, a Lexus ES (gussied up Camry), an old Subaru, an old Saab, and a Toyota MR2 and all of them developed rattles in a very short period of time. It's unavoidable unless you want to rip the car apart and add 100 lbs of Dynamat. That **** is heavy; I don't think that weight estimate is an exaggeration.

in all my cars, I have been able to find all the rattles! They bother me so much that I will hunt them down and fix them. Its usually something that has come loose over time.

How do you fix them? A lot of what I've found has been unfixable - an area where the dash slightly touches the windshield for example. Sure, I could shove something in between, but eventually that will come loose too and it looks like crap. Have you found things you can actually just tighten up?

you arnt too far off. i hated adding the amount i did, and will continue to add to my car but as a daily driver the road noise starts to get to me. best way ive found is to compensate. lighter exhaust, TP's, ect. its not alot but helps me justify the added sound deadening weight. plus its disturbed all over the lower portions of the car.

I remember my toyota pickup used to rattle all the time in different places. While driving I was able to locate them. Yes, one was in the dash, but I managed to find it. Some are just lose screws and one I had to re-glue.
The dash was easy to take apart in my truck.

I remember rattling in the door, took the door apart and all it was, was the door cover was loose.

Most everything was just a loose screw!

Rear view mirror rattle in my honda, I replaced it.

My FJ cruiser, nothing rattle in that bad boy!

My Nismo, just the trunk so far, if its the trunk. Its in the trunk area. I will find out what it is when I have time.

theres a thread about the bump stops on the 09/10's being too short. they account for alot of the rattle on the hatch.

NissanGuy23 · 08-31-2012, 03:01 PM

Ive been noticing a buzz coming from the back sounds like the plastic around the hatch area, starts buzzing super loud if you hit high rpms at high speeds. Im the type that is highly annoyed by rattles, my shifter rattled but i fixed it.

Mine is a 2012 version.. I will figure it out and let everyone know what I find.. It will be this weekend. thanks!

Armhunter · 08-31-2012, 06:58 PM

Ok, so I took a good look at my trunk and i would have to agree. The bump stops are too short! When i close the trunk it latches way to easy. I will think of some way to fix it this weekend and let every one know how it goes. It need more pressure on that latch to stop it from moving. A solution is on the way!

Fixed the trunk rattle, It was easy to do. Went to Albertsons, which I am sure other places have them cheaper. I paid $1.99 I think. Doesnt matter to me.. Anyway, here is what I bought: Felt Dots:

And I placed them in the grooves where the bump stop sits. Here:

I just dynamatted my entire hatch. It took 5 hours or so but gave me confidence to rip open my doors too. Go to a dealer and ask the service manager to tell you how to rip open your doors and hatch. They have awesome service manuals that you can look at for about 10 seconds and know basically how to do it without f'ing up your trim. Also there are utube vids how to take apart your doors. They helped me s lot and I did it all without breaking anything.

The Dynamat made my road noise on "very textured" California roads go from unbearable to merely annoying. Im going to do some research on which areas the Dynamat helps most and add sparingly.

If you tap around on your car and find areas that "ping" instead of going "thunk" you can probably Dynamat the critical spots without going overboard on weight.

I carpeted my hatch, and then took a box of 4 sheets and put the stuff up around my shock towers and up in the fenders in all the spots that "ping". It helped a lot. ImageUploadedByTapatalk1346870267.997754.jpg

SurfDog · 09-05-2012, 01:40 PM

That shot is about my halfway point. 2/3 of my first box ( I usef two)Once done the thing was blanketed.

If I were to do it again I would tap around my entire cabin and mostly just hit the spots that ping. (to get better results with less weight)

The clutch rattling noise is the dual plated clutch rattling together WHICH IS NORMAL on the 350z and 370z which i have owned/own both.

When you press in the clutch the plates are compressed and then the noise is gone.
Example shut your car off in neutral with the clutch out. Noise will be heard.

Then press the clutch in and shut the car off... NO Noise....

All normal boys its just due to the twin plated clutch.

I agree with volk z!
Same
On my 07 350 and on my 09 nismo
