What Causes the Abnormal Noise When Releasing the Clutch in First Gear?
2 Answers
Abnormal noise when releasing the clutch in first gear is caused by wear or jamming of the clutch release bearing, or looseness due to wear of the release lever pins and pin holes. Clutch release bearing wear or jamming: If the clutch makes a metallic impact noise during engagement or disengagement, especially more noticeable when starting with a heavy load, it is due to excessive clearance between the driven plate spline hole and its shaft. In severe cases, inspection or replacement is required. Looseness of release lever pins and pin holes due to wear: If the clutch can return to position on its own, check whether the gap between the release bearing and the release lever meets the specified standard, usually 3-100px. Adjust if necessary. If the clutch cannot return to position on its own, the return spring of the release bearing is likely damaged and should be replaced promptly.
I've encountered a similar situation before - a clicking or squeaking noise when releasing the clutch in first gear, which is quite common in older vehicles. Most likely, it's due to severe wear on the clutch disc. Prolonged half-clutch operation causes excessive friction that thins the disc, resulting in uneven contact and abnormal noises when releasing. Alternatively, it could be a worn release bearing - when the pressure-bearing bearing deforms, it produces noise. Less commonly, excessive gear clearance inside the transmission might also cause sounds. I remember my decade-old car had this issue several times; after checking the pedal travel and finding no abnormalities, I promptly replaced the clutch disc at a repair shop, and the noise disappeared. My suggestion: first observe the noise frequency - if it occurs every time you start, it indicates deteriorating components that need immediate attention. Having technicians inspect the clutch system during regular maintenance can prevent this issue - don't wait until breakdown to fix it. Remember, driving safety comes first - timely repairs save both money and hassle.
