Strange Nismo Noises
 

Whats up guys - as some of you new - I'm a new Nismo owner. I've had the car now a few days and I have a few questions about some noises I'm hearing. Sorry if these are really stupid questions... I just have BAD OCD, and want to make sure everything is okay. So thanks for all the help in advanced!
:tiphat:

Here is the low down:

1) Parked, in Neutral (car running), with the Clutch NOT Depressed (my foot off of it) = It sounds like something is "spinning", maybe even a lit "rattle"? Is this just the clutch?

2) When changing gears from first to second, or downshifting from third to second - there is something like a light "clanking" noise - I'm guessing the clutch or gearing. Is this normal?

Thanks again guys!

From what I have read and heard myself its normal. Think of it as a race car not sports car they are loud and not quite. The trans is cranky(loud) but you’re dealing with power and race components.

1. I have exactly same noise and I saw others complained about it too. When you press the clutch down, however, the noise is gone right? I guess it's normal.

2. It could be you didn't shift from 1st to 2nd smoothly. It will take some time to get used to. When your SRM is on, try not to apply gas when you shift from 1st to 2nd.

I have the same exact noises, and wondered about them myself! Guess its normal then. Super smooth shifting can mostly illiminate it

Yea, when I press clutch back down it does go away.

I am begging to think I am just being smooth enough....

I don't know if this helps but the Vehicle Dynamic control make lots of funky noises and my new 2013 Nismo makes clinking noises while shifting into first and various times. The dealer contacted the regional rep and he verified this IS normal. Here is the link to the 2012 370Z manual: http://www.nissan-techinfo.com/refgh...issan-370Z.pdf Look at page 5-28. I hope this helps.

The noise you hear when the clutch is out, engine running and in neutral is the throw-out bearing. This is a normal noise in all standard transmissions.

Thanks for all the info guys. I'm starting to feel alot better!

:tiphat:

I think what you are hearing is pilot bearing and for some reason Nissan has noisy bearings. Usually they are quiet and I think personally it is a design flaw. I have the Nismo and a 370z sport and they both make the same noises.

Trans noise is normal too it makes a lot of clunking and clicking when switching gears.

all normal sounds....

just wait until your hatch rattles ;)

i think mine has already started.. Did you fix yours? Strong bumps make it clank... I need to try to fix it.

oh god. what else do i need to expect... lol.

thanks for all the info by the way.:tiphat:

I was worried too when i first drove the car home 2 weeks ago. To me the transmission sounded really clunky/mechanically shifting from 1st to 2nd and 2nd to 3rd at low rpm like around 2000, at the same time it didnt feel bad.
In a way i just thought this is how a true rwd sports cars (my first rwd car) transmission is like given that shifting is more direct and it is also closer to me than all other manual fwd cars where the transmission is more in the engine bay.

Glad to read this thread and know its more normal than not.

^^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.

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...

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.

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!

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:

:tup: HOLY CRAP! Thanks for this - just did the same thing (got mine at bed bath & beyond). That **** works! lol.

:bowrofl:

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. Attachment 53789

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

This has gotten a little off topic, but hopefully nobody minds...

I have a rattle somewhere near where my dash meets my windshield and I can't figure out what it is for the life of me. I thought it was the plastic fittings around the gauge cluster but that doesn't seem to be it. Anybody else have this and figured out what it is? It's driving me insane.

No. I haven't hurd that noise yet... Did anything fall from the dash into the back of the gauge cluster?

I know I was reading someone got a Mini Pen jammed in there and it was doind all sorts of stuff before he got it out.

This is great information. THANK YOU!

:tiphat: Rep Points!

I'm sure you have already said this somewhere, but how many pounds of mat did you add?

Thanks Man, glad to help!

yup, normal noises. the 2nd gear shifting noise is probably the diff moving a little bit. it's meant to do that (that which does not bend, will break kinda thing). making sure to push the clutch all the way in for that shift may help. also, double check your brake master cylinder and slave cylinder fluid levels, if you are a little low on clutch fluid you may not be getting full pressure on the throw out bearing so the clutch would be slightly more engaged than it should be causing the transmission to "clunk" into gear, tho i would think if that were the problem it would be noticeable on most gears

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.

:facepalm: did you try reading the rest of the thread?

Sorry I didn't get a chance to read the whole thread just the posts today. lol

Hey guys, sorry to revive this thread. I'm a new owner and was searching the forums and came across this thread basically describing what I have.

In neutral, clutch out, idling and I get a whining noise. Clutch in and it's gone. Let it out and it starts up again. Looks to be the input shaft bearing and you guys are saying this is normal? I have 17k miles. Other than the whine, the car shifts fine and no other odd noises.

I'm just curious because I've also read threads on other forums saying that the whine is the first sign of the input shaft bearing failure which can cause harm to the gears and could ultimately ruin the trans. Am I just over-reacting?
