What is the reason for the abnormal noise in the Wuling Hongguang S clutch pedal?
3 Answers
The reasons for the abnormal noise in the Wuling Hongguang S clutch pedal are as follows: Reason one: Bearing damage, the noise will still exist when the clutch is pressed, but after cutting off the power, there is no load, and the noise will decrease. Reason two: Pitting on the tooth surface, similarly, due to the absence of load, after cutting off the power, the speed of the first shaft will decrease, and the noise will gradually reduce. Reason three: Scraping between the synchronizer sleeve and the engagement teeth, as the shift fork wears during use, after reaching a certain amount, it may cause the sleeve to not be in the center, leading to possible scraping. After pressing the clutch, the noise will also gradually decrease.
Last time my Wuling Hongguang S also had this issue, it made a creaking noise when I stepped on the clutch pedal while driving. Upon inspection, I found that the clutch pedal spring was lacking lubrication, and the increased friction between the spring and the bushing caused a metallic grinding sound. Another common reason is a loose clutch master cylinder push rod, which connects the pedal to the master cylinder. Wear and tear can cause it to wobble and create noise. When I dealt with it myself, I sprayed some WD-40 lubricant on the spring area, and it immediately quieted down. However, this is just a temporary fix. It's best to take it to a repair shop and have a mechanic check the release bearing and clutch slave cylinder to prevent a minor issue from turning into a major fault. After all, I use this vehicle for hauling goods daily, and the clutch gets used very frequently.
A friend's car just had a similar issue fixed—there was a clicking sound when pressing the clutch pedal. The key is to identify the sound's location: if it's coming from inside the cabin, it might be due to worn or cracked bushings in the pedal bracket; if the noise is from the engine bay, it’s likely a sign the release bearing is failing. Wuling vehicles often face rust issues with the shift fork shaft, especially after the rainy season. It’s best to address this early—I’ve seen cases where people waited until they couldn’t engage gears before repairing, ending up spending over a thousand on a clutch kit replacement. Also, avoid keeping the clutch pedal depressed at traffic lights—this habit accelerates release bearing wear.
