Reasons for abnormal noise in the clutch pedal of Wuling Hongguang S
2 Answers
The reasons for abnormal noise in the clutch pedal of Wuling Hongguang S are as follows: 1. Severe wear or lack of oil in the release bearing, or the bearing return spring being too soft, broken, or detached; 2. Wear and looseness between the release lever bracket pin and the hole; 3. The pedal return spring being too soft, detached, or broken; 4. Loose rivets on the driven disc, fractured steel plates, or broken damping springs. Additional information: Fault diagnosis and troubleshooting: 1. Press the clutch pedal to make the release lever contact the release bearing. If a "grinding" sound is heard, it indicates noise from the release bearing. If the noise persists after lubrication, the bearing is worn or damaged. 2. After releasing the clutch pedal, increase the engine speed. If there is an intermittent impact sound, it indicates noise from the release bearing sliding back and forth. Remove the clutch bottom cover and check if the release bearing return spring is broken or detached. 3. If noise occurs when the pedal is fully depressed and disappears when released, it indicates wear and looseness between the intermediate pressure plate drive pin and the pin hole of the clutch. 4. If noise occurs when the clutch just engages or disengages while repeatedly pressing the pedal, it indicates wear and looseness between the release lever and the bracket pin and hole, or loose and exposed rivets. 5. If noise occurs when the engine starts and disappears when the pedal is lifted, it indicates burning or damage to the release bearing.
My Wuling Hongguang S clutch pedal is making abnormal noises. The common causes are lack of lubrication at the pedal joint—after driving for a while, the oil dries up, causing a squeaking sound. I encountered this issue during a long-distance drive before, and it was quite uncomfortable when pressing down. Additionally, loosening or rusting of the connecting rod linked to the pedal is also highly likely, especially since Wuling's chassis design is simple, making it prone to loosening on uneven roads. If the release bearing is worn out, the noise may become more noticeable when pressing deeply, even affecting gear shifting. Lubrication is the first solution—I tried applying some engine oil or grease, and it became much quieter instantly. However, if the sound is sharp or recurring, it’s best to quickly visit a repair shop to inspect the clutch system. For prevention, regularly check the pedal’s free travel and apply lubrication—this can save a lot of money and avoid clutch burnout or breakdowns on the road.
