What Causes the Abnormal Noise in the Clutch Spring of a Car?
3 Answers
Possible reasons for abnormal noise in the clutch spring of a car include: insufficient lubricant in the release bearing; no clearance between the release bearing and the inner end of the release lever; severe oil contamination or dust accumulation between the release bearing sleeve and the guide tube; excessive looseness in the spline hole of the driven plate and its spline shaft; annealing fatigue or breakage of the driven plate damping spring; loose rivets or exposed rivet heads on the driven plate friction disc; and excessive wear in the drive pins of a double-disc clutch and the pin holes in the intermediate pressure plate and pressure plate. The diagnostic and troubleshooting methods for abnormal noise in the clutch spring are as follows: 1. Slightly depress the clutch pedal to make the release bearing contact the release lever. If a 'rustling' sound is heard, it indicates abnormal noise from the bearing. If the noise persists after lubrication, it means the bearing is excessively worn or damaged and should be replaced. 2. Depress and release the clutch pedal. If intermittent collision sounds occur, it indicates axial movement of the release bearing, and the return spring of the release bearing should be replaced. 3. Continuously depress the pedal. If noise occurs when the clutch is just engaged or disengaged, it indicates loose or exposed rivets on the driven plate, and the driven plate should be replaced.
I've been driving for decades and have encountered clutch spring noise issues several times. It's mostly caused by spring aging or fatigue fractures, especially in older vehicles. The springs inside the clutch pressure plate undergo long-term compression and stretching, which weakens the material over time, leading to cracks or even breakage. There's often a clicking sound when depressing the pedal, which can be quite annoying. Other possible causes include loose spring installation or lack of lubrication leading to increased dry friction. If ignored for too long, clutch functionality will deteriorate, making gear shifting difficult and compromising driving safety. I recommend car owners regularly inspect the clutch system and maintain proper lubrication; if the noise persists, promptly visit a professional shop to replace the springs to prevent minor issues from escalating into major accidents.
I'm a DIY car enthusiast who has researched clutch spring noises. Common causes include spring fatigue deformation or improper installation. Once the spring becomes loose or breaks, you'll hear annoying squeaking or creaking sounds when pressing the clutch. I remember when my old car had this issue - after disassembly, I found the release spring was slightly bent, and replacing it solved the problem. Additionally, insufficient lubrication or accelerated wear can cause this, possibly due to oil contamination or part aging. For DIY solutions, you can try applying lubricant first, but be careful not to damage other components. Generally, avoid aggressive clutch pedaling during driving - smooth gear shifting reduces spring stress and extends lifespan. If DIY doesn't work, it's safer to seek professional help.
