Clutch Rattle

kjay82

I don't know if there is another thread to this, but here goes...

I have about 7k miles on my Z and I've been having this "problem" ever since I got my car..
Being that this is my first manual car, I don't know too much.

When I depress the clutch while switching gears, I feel the clutch rattling like crazy under my foot, like it's having a seizure or something. It doesn't jump and go all over the place, it just feels like it's going crazy. Like it's tapping back at my foot. This also happens when it's fully depressed.

Is there a problem or is it just because of the car?

It's pretty weird cuz after reading some posts about driving barefoot, I had to try it. It felt really nice. When I did this, I didn't feel anything.. lolz..

dunno, just thought I might throw this out and try to get a more technical explanation to this..

your responses are appreciated..

Thanks in advanced..

i feel that too. like when i'm in first, waiting to make a left turn with my foot on the clutch. sometimes it annoys me if i'm holding the clutch down for a bit because i'm stuck wwaiting to turn. it feels weird but i think its normal.

kjay82

yea.. it does get annoying, but again, like all tranny problems with the Z, I think it's a normal thing too..

I was just reading a thread "Z vs Gen" Gen or GC = genesis coupe and there were a lot of interesting facts on there. You should read it, it's quite funny, yet very technical..

oh and btw, thanks for your input.

Mine does this too....it can't be normal....at least in my opinion at least. I've had 3 other 350z cars....and this is 370z is the first one to do this. I thought maybe it was the flywheel or pressure plate....not necessarily the clutch. I'm taking it in this afternoon to have it looked at......I don't want to because of rental car costs, etc.

This is completely normal. Everyone has said that their clutch has a little vibration to it.

i concur

NISMOFO

Maybe when I'm at the dealer ill test drive another Z to see if it does it as well.

Mine does that too, if im at a red light and in 1st gear and im holding the clutch down waiting to go, I feel it rattling a little bit. I have driven a few 370Z's and also i owned a 40th anniversary before this and that did it too, so im almost positive its normal.

Throw-out bearing. Call it "foot massage."

NISMOFO

Lol......so bad throw-out bearing? Or normal throw-out bearing?

Dealer wants me to bring it back when their Z specialist is in town. Service Advisor couldn't hear or feel it......yet when I got back in the car I felt it immediately.

After driving it with me, he said the car acted like it was double-clutching...weird....lol.....I said, you mean the rev-sync? He didn't know what that even was.

I can't believe this sound and feeling is considered normal. If I had a lighter flywheel, I'd expect this....is the stock 370Z flywheel light compared to a 350Z flywheel?

I don't know whether to laugh or cry about the SA's comment about double clutching!

I get this, too. It is more noticable sometimes. From what I've read here it is "normal" for these cars. Until of course you need a new clutch or throw out bearing.

I'll probably bring it to the attention of the SA when I go in for service (this will be my first service appt.) just to get it on record in case something goes wrong down the road.

Ok. first of all, if u have the rattle sound on 1st 2nd and 3rd gears u cant shift and if u hear it in 4th 5th and 6th gears u should kill yourself. Now that sad plz allow me to explain my self i recently purchased a 2010 nissan 370z i had that rattle since day 1 and since i live in new york city Bk (not Burger King ) its all stop sign every 100 yards or less i currently put over 900 miles on it, every time i take it out i practice shifting and that rattle is always the same and also gear grinding on 3rd and 5th until i drive for about an hour and it dissipates i don't hear it anymore and am like WTF? Where is it? so then i turn to the post as i read the post everyone has this problem so am thinking ( Duh) read the damn manual see what the manufacturer says and they say that if u do hear rattle ur shifting is wrong basically 1) the clutch has to be in all the way in every shift maybe not 5th to 6th but definetly 1 to 2 to 3 to 4 to 5 2) when u shift the gears u must give half a sec delay between shifts like 1 to N (pause on N for about half of a sec then) N to 2 then when rdy back to N (pause on N for about half of a sec then) N to 3 when rdy 3 to N and so on this shifting technique is done when ur moving slow basically the faster you drive the faster the shifting has to get. 3) this is the most important thing is the connection when you let go of the clutch must be smooth ( sometimes when u feel the cars tranny connect to the flywheel dont let go too early but wait about half a sec to sec for them to synchronize then let it go ) it takes practice but remember practice makes it perfect i drive now barely ever hearing the rattle. As soon as i start to f@ck up the rattle comes back cold or hot tranny tried it on both. So try this out tell me what are ur results.

PS. this tranny is very sensitive and nasty u need skill to weld it, but its strong and when you get it all right in combo OMG the engine just purrrs like a kitten very smooth very nice.

sometimes its especially noisy for a minute or so when you've, lets say, driven home from work, and pull into your driveway/garage and you get out with the engine still running the clutch sounds like its rattling, then it goes away. anyone else have this happen?
