Clutch noise is another problem that may be tricky to pinpoint. If a squealing or chirping noise appears or goes away when the clutch pedal is depressed, the cause may be a bad release bearing. Other causes include a bad pilot bushing, a worn or defective input shaft bearing in the transmission, a worn, bent or improperly lubricated release fork, a worn input shaft, improper disc installation, misalignment, damaged bearing retainer, loose flywheel bolts, damaged disc splines, or worn stop pins or broken damper.

A growling or grinding noise when the clutch is engaged may be due to a bad transmission input shaft bearing.

A squealing sound that occurs when the clutch pedal is depressed and held is usually caused by a bad pilot bearing or bushing.

A chirping noise that intensifies when the pedal is slowly depressed would indicate a bad release bearing.

If you hear chirping while idling in neutral and the noise goes away when the pedal is slowly depressed, the fork/pivot ball contact point is making the noise
