What causes the squeaking sound when pressing the clutch on a Wuling Hongguang?

[OJune]

Wuling Hongguang may produce abnormal noise when pressing the clutch due to worn clutch plates or broken clutch pressure plate springs, which requires replacement of the clutch plates or clutch pressure plate springs. The following is an introduction to the car clutch: 1. Introduction: The car clutch is located in the flywheel housing between the engine and the transmission, and the clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the transmission. 2. Function: During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the transmission, thereby cutting off or transmitting the power input from the engine to the transmission.

I encountered this issue last time when I was delivering goods in my Wuling. The clutch squeaks every time I press it, and there are usually three common problems: the release bearing lacks lubrication and grinds dry, producing a high-frequency metal friction sound, like the noise from a rusty door hinge; the rubber bushing at the clutch pedal pivot point wears out over time, causing a creaking sound with each press; and the clutch fork pivot lacks grease, leading to direct metal friction and a squeaky noise. I once tried spraying WD40 on the pedal pivot as a temporary fix, but it only addressed the symptom, not the root cause. To solve it completely, you need to disassemble the gearbox to replace the release bearing and apply high-temperature grease to the fork pivot. For DIY-savvy owners, you can check the rubber bushing under the pedal—if you see cracks, replacing the bushing for about 20 bucks can significantly reduce the noise.

My Wuling van with 80,000 km on it had similar issues before. Focus on three key areas: First, apply some grease to the pedal spring to see if the noise persists - dry metal fork pivots can produce rusty hinge-like sounds, while a lack of lubrication in the release bearing's steel balls creates high-pitched squeaks. Easy diagnosis: If the clutch pedal makes noise when pressed in neutral, it's likely a pedal assembly issue (80% probability). Noise only when depressing the clutch with the engine running points to release bearing or fork problems. Last time, my brother's car had a polished fork pivot - after applying high-temperature grease, it stayed quiet for six months. But if you hear a crackling sound like broken glass, don't ignore it - that means the bearing balls have disintegrated and require immediate repair.

Fellow drivers who use microvans for cargo hauling all say this is a common issue with the Hongguang. That squeaking sound is mainly caused by dry metal friction: cracked plastic bushings on the pedal shaft can make the rotating shaft wobble and produce a rattling noise; the shift fork shaft without lubrication sounds like a rusty hinge creaking; and a lack of oil in the release bearing can cause a high-pitched screech like chalk on a blackboard. A mechanic at a small repair shop taught me a quick fix: cut a piece of bicycle inner tube and wrap it around the pedal shaft as a temporary rubber bushing, which can last for a month or so. One auto parts store mechanic removed the driveshaft cover plate and found that the pushrod of the slave cylinder was bent and rubbing against the shift fork—straightening it immediately silenced the noise. The design of this vehicle has tight clearances, and long-term heavy loads can easily cause uneven wear on components.
