Hello! Alright so my 240 started to make a strange noise the other day. I let someone test drive the car (considering a trade). After the test drive, which wasn't any harder than what i would have ran the car honestly i heard a few unpleasant noises coming from either the transmission or the insides of the bellhousing. The car has a Spec flywheel and a Spec stage 2 clutch with about 25,000 miles on it. The throw out bearing has always made a little more racket than it should which is strange considering the amount of mileage on it. "supposedly" the transmission was rebuilt when i bout the car and swap about 3 years ago, it shifts fine in all gears but it has also sounded a little more mechanical than what it should i believe. The noise I'm posting about though is squealish, almost how a car door sounds when it isn't shut all the way and your driving down the road, it has a whistle to it sort of...just much louder and occurs spontaneously. Yet all this used to happen under a little amount of load, now the the noise can stay while cruising until i depress the clutch.

i took a video, the noise I'm talking about happens right as i pick my phone back up off my lap, and continues randomly throughout the rest of the video.

If anyone has any information please let me know, on a side note i did not change my pilot bushing when i changed my flywheel/clutch the first go around (slipped my mind :facepalm: )
Thanks in advance everyone.

That tapping noise sounds like the ebrake cable hitting the drive shaft. other than that I can't hear anything but fuzz.

I apologize for the terrible sound quality. I'll try to make another video today and see if I can catch the noise again. Thx for the info bout he ebrake cable though! I'll check that today.

Not sure if the 91 is the same ebrake setup as the 95 but mine made that noise cause the cables slipped out of the bracket just over the diff. It was kinda hidden but easy enough to get to.
