What is the reason for the squeaking sound when releasing the clutch?

The reason for the squeaking sound when releasing the clutch is poor lubrication, wear, looseness, or damage to the clutch release bearing. It is necessary to add lubricating oil to the clutch release bearing or replace it in time. The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the transmission, thereby cutting off or transmitting the power input from the engine to the transmission. The clutch is a common component in mechanical transmission, which can separate or engage the transmission system at any time.
When I encountered a squeaking noise while releasing the clutch while driving, I found it quite annoying and decided to investigate on my own. Typically, this kind of noise stems from issues with the release bearing—either it has aged or lacks lubrication, causing friction and noise every time the pedal is lifted. Over time, this could even damage the entire clutch assembly. It could also be due to fatigued pressure plate springs or uneven friction discs, leading to poor engagement and resulting in noise. I tried applying lubricant myself, but the effect was temporary. Later, a friend pointed out that a professional inspection was necessary. Don’t ignore this issue, or the clutch may fail prematurely, leading to costly repairs. My advice is to visit a repair shop as soon as you hear squeaking—don’t wait until it causes bigger problems and disrupts your trip.
