What Causes the Noise When Pressing the Clutch?
2 Answers
Clutch noise when pressed is caused by: 1. Damaged release bearing; 2. Worn clutch disc; 3. Broken diaphragm spring. If this occurs, car owners should inspect these components. The clutch is a crucial part of the engine's transmission system, connecting or disconnecting the engine from the gearbox. Every time you start or shift gears, you need to depress the clutch pedal to ensure smooth operation. The clutch disc has a spline in the center that secures a driveshaft, which serves as the gearbox's power input shaft. Damage to the clutch can affect the vehicle's power output.
I've encountered the issue of the clutch making noise when pressed several times. With over 20 years of experience driving manual transmissions, I'd say there's an 80% chance it's due to wear on the clutch release bearing. The squeaking sound when pressing down is particularly noticeable. Sometimes, insufficient lubrication or lack of grease in the bearing can also cause such noises. Another possibility is loose or deformed springs on the pressure plate, causing the disc to vibrate and produce noise when the clutch is engaged. Don't underestimate these small sounds—if you delay repairs and the bearing fails completely, it'll be even more troublesome when the clutch won't engage. The inspection method is simple: start the car in neutral, press the clutch repeatedly to listen for changes in the sound, and applying some grease to the pedal joints might provide temporary relief. Remember to avoid prolonged half-clutch driving in daily use, minimize grinding the clutch disc in traffic jams, and perform regular maintenance and oil changes to extend its lifespan. If any abnormal noise occurs, have it inspected by a professional shop as soon as possible.
