PROBLEM: when pressing in clutch ABOVE 4k RPM I get a low pitched whine and a slight vibration in the clutch pedal. There is no whine if in neutral and clutch is out or when winding up RPM's in gear. Anyone have any ideas? I have JWT clutch & flywheel combo but had 1500 trouble free miles before this noise popped up.

The noise is very audible when in the car with windows up and very difficult to hear when listening from outside the vehicle.

WHAT I HAVE TRIED: Since the noise happened only with clutch, my first guess was the throwout bearing. So, last night we pulled out tranny, clutch, flywheel (after removing exhaust, driveshaft, etc.!). We inspected every component and found no obvious defects. Since we had it out, we replaced throw out bearing anyway. We re-installed everything (throwing in a Rogue shifter while we were at it!). The sound is STILL THERE!

Any of you have any ideas on what to check next or the cause of this whine?

 

if its a "honking" type noise while shifting at high rpms, then i have the same prob....whenever clutch is depressed

still looking into what it is, but so far unsuccessful.

i did top off my fluids and it seemed to help a little.

my only drivetrain mod is a nismo flywheel

 

Sounds like the SAME thing! Have you taken it to delar yet?

 

havent taken it to the dealer yet due to personal time constraints.

i hate spending all day at the dealer.

i think i'm going to bleed the clutch first to see if that helps.

 

Let me know if bleeding clutch helps. I have to talk with my mechanic this weekend to see next steps we will try. Time is an issue for me also so I probably won't get a chance to work on the problem for about a week or so. I will update if we find anything.
