Ok so I have a 2005 350z Enthusiast 6 speed with 81k miles on it. I just bought it the other day and everything seemed fine. I drove it home 2 hours and it was all good. Later on in the day i discovered a rattling sound I did not hear before. It seems to be coming from underneath the car. The clutch on the car is on its way out because it catches pretty close at the top. The rattling seems to go away completely when I push the clutch down to the floor. I've heard it could be the throw out barring from a few people. But could it just need an entire new clutch? The sound isn't too loud yet but loud enough for it to get a little bit on my nerves. Everything else with the car is great. Shifts like butter. The noise also seems to increase when I go up a hill in 1st gear. What do you guys think?

 

I have rattling but it's from my ACT Streetlight Flywheel.

Might wanna check under the car for any loose bolts, exhaust shields etc... then start digging into the clutch if you think you need to. I have interior rattles that drive me insane though.

 

Don't worry about the rattle it's normal for our cars and clutch engages at a higher point which can be annoying to get used too but normal also. Put your issues in search box and you will find plenty info.

 

what if i told you the clutch does catch till i take off the floor almost 90% up? and heard alot of people have a similar rattling, i would just like to get rid of it if i can.

 

my 05 rattles alot from the spec single mass flywheel and exedy stage 1 clutch, throwout bearing noise is very common you'll just have to get used to it.

Nothing you can really do about it and if you go with a single mass flywheel and aftermarket clutch then its only going to get worse. If your going to get a new clutch id advise getting a new flywheel also, had a friend's race shop try to fabricate a jig and re-surface the dual mass flywheel and it was a pita for them not to mention they couldn't do it, so i just went with a single mass.

Best thing you can do is turn the radio up or keep the rpm's higher.

 

The noise seems to get worse when i accelerate too, again is that not normal but common?

 

Clutch chatter is very common unfortunately it's an ear sore at times. When you accelerate do you always hear it? Normally after I get going I don't hear the chatter anymore.

 

I hear it most when im in neutral and i rev it up to about 3000 rpms. and i hear it in 1st gear going into second. once im in third and so on it goes away. and goes away when i floor the clutch.

 

I'm starting to think its the flywheel

 

apparently i have this same problem only on first going up hill? i haven't thought of it as a prroblem as i thought our cars come with clutch and tranny noises..? i dirve a 03 123k 6speed touring the car is in great condition no unnormal noises besides going up hill i always thought the lack of gas and engaging the clutch point would cause it to skip out alittle? ( driver error ) obviously.

 

So I took it to Nissan and they looked at it for not even an hour and told me I need a new clutch AND transmission. I'm calling ********

 

Well guys got a second opinion from a trusted friend and he says transmission and clutch. And all the symptoms are there. Well I'm taking her back for a full refund
