this problem just started recently. when i turn the car on, i hear a weird humming noise and it goes away when i press the clutch. once i release the clutch it comes back. it happens when its in neutral and driving.

VIDEO:

 

Uhmm, your video is private.

 

it should work now

 

Yeah, although the exhaust rumble overtone is pretty strong, it does not sound like just the classic clunking gear noise that is common. It sounds more like a bearing noise to me. Is it possible to post another video, just like that one, but with you slowly revving the motor so we can hear how/if the sound varies with engine rpms?


BTW, nice kicks

 

after doing a lot of research, ive pretty much narrowed it down to the "input shaft bearing" does anyone else agree? how much is the replacement

 

how many miles on yours? did you change the transmission fluid?

 

80k and no i havent

 

will changing the transmission fluid fix the problem? the sound is a loud humming. not as bad as other people on youtube

 

you can try. it happened to me when i had G35, with the same noise. i changed the transmission fluid and the sound disappear.

 

any other suggestions? ill try changing the transmission fluid sometime soon

 

If it's a bearing, it will need replacement. I will say this is very unusual/atypical though, so again my question: Is there any chance this was a flood car?

 

no its not a flood car. its clean title.

 

Same EXACT noise from my '08 S. Only happens when the clutch isn't being pressed.

Changed the fluid today and the noise is still there. I'm 99% sure it's the throwout bearing, which would explain why it goes away when it's pressed (because now there's pressure on it).

Anybody know approx. how much a shop would charge to replace it?

 

its not the throw out bearing. its the input shaft bearing. I just ordered fluid so its coming any day now. The noise isn't as bad as other people so that's why I have slight hope this fluid change will work.

 

could be throw out bearing
