Manual Transmission Clutch Throwout Release Bearing Failure
ModerateGearbox & TransmissionManual transmission GT86 models suffer from premature wear and grease drying in the factory clutch throwout (release) bearing between 40,000 and 70,000 miles. The defect begins as an irritating high-pitched chirping whistle when idling in neutral that disappears when depressing the clutch, eventually deteriorating into a loud metallic grinding noise, stiff pedal travel, and catastrophic bearing disintegration that scores the transmission quill sleeve.
High-pitched chirping or whistling noise at idle with foot off the clutch pedal, Grinding or scraping sensation through clutch pedal during gear changes, Difficulty selecting 1st and reverse gears when stationary
- With engine running in neutral, rest foot gently on clutch pedal to see if chirping changes or stops
- Check invoices to see if an updated 2017+ revised release bearing or full clutch kit has been installed
