MAYHEW820 Posted April 24, 2009 Share Posted April 24, 2009 Since the wife brought her Zed a few weeks back I have noticed a Release bearing/Gearbox noise when running in neutral with the clutch up. In my heart of hearts I feel that there is no problem but it's a more elevated noise than I've been used to with all of our previous FWD transaxle cars. Clutch operating is totally fine and the noise doesn't really change with different temperatures either I have no reference other than to see how much noise is emitted from you guys and girls Zeds when idling in neutral. Just searching piece of mind really or whether to get it looked at as it's under warranty. Unfortunately I am one of these people who wants his&her car to spend as little time as possible in a dealer. Hope you can help Quote Link to comment Share on other sites More sharing options...
Trev-the-Rev Posted April 24, 2009 Share Posted April 24, 2009 This is a trait of the Zed and nothing to really worry about. Quote Link to comment Share on other sites More sharing options...
M13KYF Posted April 24, 2009 Share Posted April 24, 2009 +1 it it slighter louder/noticeable when in neutral an clutch up Quote Link to comment Share on other sites More sharing options...
MAYHEW820 Posted April 24, 2009 Author Share Posted April 24, 2009 Thanks guys, When the clutch is down there is no noise at all! When it's up there is just a faint wine from her gearbox. I felt in the first place it's down to the Z having a strengthy gearbox and bearing noise being a bit more noticeable. On the road and under load, perfect.

M350ZB Posted April 24, 2009 Share Posted April 24, 2009 Common prob, even chatting to a guy who had a late late 58 plate, and he had the same prob, he was quite worried but mine been doing it for ages Quote Link to comment Share on other sites More sharing options...
Chris`I Posted April 24, 2009 Share Posted April 24, 2009 Nothing to worry about as the others have said. Just a trait of the Zed that gives it some character Quote Link to comment Share on other sites More sharing options...
Gilly199 Posted May 20, 2009 Share Posted May 20, 2009 Sorry for a newbie dragging up an old topic But thanks to all for this as i have the same bloody annoying problem, lift the clutch in neutral an idle and yup you guessed it grrrrrarrrrrgarrrrrr lol. but sometimes when the the above situation si in place you can hear a knock, or clunk and feel it throught the clutch pedal. Again is this normal, or should i worry??? Gilly Quote Link to comment Share on other sites More sharing options...

dcash5 Posted May 20, 2009 Share Posted May 20, 2009 I would argue it could be 1 of two things.. yes the release bearing could have gone but also (and it occured in mine) The 350z operates a dual mass flywheel option (simple way to explain it is it has one fly inside another that give a bit of flexibility when engaging gears. Its not that common in road cars more found in trucks and tractors etc, but does mean the engage is quietened down. If the inner flywheel has lost its spring or resistance, it will just bounce against the metal stops making a horrible noise. When mine went the clutch bite was perfect just made a load of noise when engaging the clutch and when not engaged. One it has fully bitten the flywheel is just runing on the stops so doesnt move, therefore no noise. Unfortunately the only way to find out is a box off job.

D350z Posted May 20, 2009 Share Posted May 20, 2009 My 08 350z with 3800 miles on the clock has the same release bearing / input shaft baring rumble in neutral with the clutch up. I've been told it's a Z thing Quote Link to comment Share on other sites More sharing options...

pernickerty Posted June 3, 2009 Share Posted June 3, 2009 Just bought myself a 350z on Monday evening and went for my first decent distance (150 miles) drive last night. Got back home and parked on the drive and noticed the in neutral clutch released noise, made me quite concerned. Read this thread and feel much better, even about the odd random knock, as Gilly said. I will assume it's normal unless there's any change. Quote Link to comment Share on other sites More sharing options...
Ebized Posted June 3, 2009 Share Posted June 3, 2009 Having been on this forum for some 3 years I would say more ZEDs seem to have this 'issue' than don't and rarely ever has it been reported that it led to actual clutch/release bearing/flywheel/gearbox problems. I had it my 04 ZED and sometimes hear it in my current 56 ZED - a trait that seems nothing to worry about. There is no doubt that the gearchange is not 'sweet' until the box has warmed up and I always give the throttle a little blip when going up or down the gears when cold, particuarly into and out of 2nd gear, to help the engine speed match the transmission speed and hopefully prolong the life of the syncros Quote Link to comment Share on other sites More sharing options...
SI 1 SFB Posted June 5, 2009 Share Posted June 5, 2009 I had a new clutch fitted 3 weeks ago on my (2007) roadster 10k miles into its life!.., see 'clutch gone at 9800 miles' . It now has a very noisy release bearing after just 300miles and it is not as smooth from 1st to 2nd as one would like! I will be taking it back to the dealer to get it checked over but I don't expect too much sympathy. I was lucky to get a full clutch under warranty in the first place.. LOL Quote Link to comment Share on other sites More sharing options...
mercurial Posted June 15, 2009 Share Posted June 15, 2009 I seem to have the same problem, quick question though, I still get the sound - if not more once the engine is warmed up, whilst sitting in idle and in neutral... also when slowly pulling off, I get a grinding noise?? My alternative was to go find a good garage in Surrey but have yet to find once that truly knows the 350z's... Some have spoken about TGM, but Tom's very much a Honda DC5 kinda guy..

Gilly199 Posted June 16, 2009 Share Posted June 16, 2009 I spoke to the workshop controller at my work and he said there was an active recall on the release bearings. It was just brought up in a convo after he seen the car. Bit i have yet to give him my VIN number to check. Yes i know it will probably happen all over again but i assume some people have had this fixed and for good. so its worth a try. Scott, the nissan master tech says the same about a black one we have had in countless times for this. The driver doesn't get the hint. Should be finding out this week, il let you know how it goes.

stanski Posted June 16, 2009 Share Posted June 16, 2009 Common problem folks dont worry about it. when they took the gearbox out last year for some recall work its been a lot quieter since - so probably not lining up properly and giggling / growling - sounds like cement swilling round a mixer with a few stones in it. Dont worry be happy and enjoy the Zed especially you softtop owners Quote Link to comment Share on other sites More sharing options...
MAYHEW820 Posted June 29, 2009 Author Share Posted June 29, 2009 Just serviced Sal's the other week and the noise comes from the very back of the gearbox under the gearstick mounts, so totally wipes out the release bearing idea. No noises under load. Plus changed the gearbox oil to check condition of it and it came out like new. Was well happy and is obviously a clear Zed Trait Quote Link to comment Share on other sites More sharing options...
