What Causes the Squeaking Sound When Pressing the Clutch?
2 Answers
The reason for the squeaking sound when pressing the clutch is: the clutch is not in good condition, its lifespan has been reached, and it needs to be replaced. The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. Steps to replace the clutch: 1. Remove the bolts connecting the clutch cover to the flywheel from the flywheel, allowing the clutch cover and pressure plate assembly to be taken off the flywheel. If the bolts are equipped with balance weights, marks should be made on the clutch cover and balance weights to ensure proper reassembly in their original positions, preventing disruption to the dynamic balance of the crankshaft assembly; 2. Place the clutch cover and pressure plate assembly on a press, supporting the lower part of the pressure plate with a circular spacer of thickness greater than 9.2mm (9.7mm for new structures) and outer diameter less than 325mm, and apply a pressure of more than 1.5 tons to hold it; 3. Remove the lock nuts and adjusting nuts of the release lever adjustment screws; 4. Remove the bolts from the drive plate bolt seats (the flanges should be unfolded during removal); 5. Gradually release the pressing force of the press. Once all pressure is released, the clutch pressure plate and cover assembly will be completely disassembled, and all parts should be cleaned and inspected.
Not long after I bought my car, I noticed a squeaking sound when pressing the clutch pedal, especially noticeable during starts. After researching and consulting friends, I learned it might be due to rust or lack of lubrication in the mechanical joints around the clutch pedal, causing friction noise when the spring moves. It could also be a deeper issue like a dry or worn clutch release bearing, which is located near the transmission and responsible for disengagement. Ignoring it could make the noise worse. I tried spraying some lubricant to see if it helps, but I recommend getting it checked at a repair shop as soon as possible. Don’t delay like I did, as minor issues can escalate into major problems, affecting driving smoothness. Regular maintenance should include cleaning and lubricating the clutch system to avoid unnecessary trouble.
