What Causes the Abnormal Noise in a Manual Transmission Clutch?
2 Answers
Manual transmission clutch abnormal noise can be caused by clutch pressure plate failure or broken clutch components. Clutch pressure plate failure: The clutch is part of the car's transmission system, fixed between the engine and the gearbox, serving to disconnect or connect the engine to the gearbox. The clutch pressure plate is mounted on the engine flywheel, with the clutch disc located between the pressure plate and the flywheel. If the clutch disc is severely worn, abnormal noise will occur when using the clutch. Broken clutch components: Broken clutch pressure plate springs or broken clutch pressure plate release levers.
I've been driving manual transmission cars for many years, and clutch noise issues are quite common. The most frequent cause is a worn release bearing - that's the squeaking sound you hear when pressing the clutch pedal. This component handles the rotational separation and tends to fail when aged. Other common issues include worn or torn clutch discs that make noise when engaged, or a warped pressure plate that causes difficulty in operation along with abnormal sounds. I once had a car with this problem - inspection revealed a completely ruined release bearing, and replacing it solved the noise. Additionally, loose input shaft bearings or internal components can also cause noise. Address these issues promptly, as the noise will only worsen over time and affect shifting safety. My suggestion is to first identify the noise location and type - whether it occurs when depressing or releasing the clutch - as this aids diagnosis. Driving habits matter too; avoid riding the clutch in semi-engaged state as this accelerates wear. When you notice abnormal sounds, get it checked at a repair shop immediately - delaying will only lead to more expensive repairs later.
