Strange Nismo Noises

sillyoldtayo · 08-30-2012, 10:32 PM

^^yah my G35 made the same noise and I noticed that the Nismo makes this noise but much quieter. From everything I have read it is the throw out bearing. everything works fine but there is a slight mechanical noise...

Just to further assuage your concerns... I had a 350Z roadster and now have a 370Z Nismo and the transmissions on both made a "ker-thunk" sounds followed by a short rattle when I fully depressed the clutch pedal. Since both cars have made that exact same sound, I presume it's normal.

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?

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.

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 just got my 2011 Nismo and have the same noises. I believe it is chatter from the cltuch flywheel assembly which is normal for a race car like the Nismo.

I hate exhaust heat shield rattling on my both Pathfinder and Xttera!! Good I haven't found this problem on my g and z, yet. Knock on the woods...

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.

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

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.

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!

Armhunter · 09-03-2012, 04:30 PM

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:
