How to deal with the abnormal noise of Wuling Hongguang S transmission?
3 Answers
Wuling Hongguang S transmission abnormal noise treatment methods are: 1. When the transmission makes abnormal noise in neutral, and the noise disappears after depressing the clutch, it is caused by the wear or looseness of the front and rear bearings of the transmission first shaft or the constant meshing gear noise. For severely damaged bearings, they should be sent to the repair shop for maintenance or replacement in time; 2. If there is a dull sound without rhythm and the sound disappears when holding the gear lever, it is caused by the wear of the gear shift fork of the gear or the wear of the lower end working surface of the gear lever. The transmission should be removed for maintenance. Wuling Hongguang S is a micro van with a body length, width and height of 4390mm, 1660mm and 1750mm respectively, a wheelbase of 2720mm, and a unibody structure.
I've dealt with many Wuling Hongguang S transmission issues before. Transmission noise is usually related to insufficient lubrication or internal component wear. After detecting abnormal sounds, I first stop to check the transmission fluid: if the level is low or the oil appears black with impurities, it indicates replacement is needed. Then I observe the noise type - a humming sound may indicate bearing damage, while a clunking noise could mean loose gears. Never force the vehicle to keep running to avoid exacerbating damage and causing transmission failure. It's safer to have a professional repair shop use diagnostic tools for inspection, as disassembly requires specialized knowledge. I understand some people want to save money with DIY repairs, but mistakes can end up costing more. Such faults typically cost a few hundred yuan to fix if addressed promptly, but delaying could mean spending thousands to replace entire components, and it will affect driving stability.
My Wuling Hongguang S had transmission noise issues, and the sound kept getting louder, which really worried me. I did a quick check on the engine oil and transmission fluid, and everything seemed normal, but the problem persisted, so I rushed to the repair shop. The mechanic said that such noises are mostly caused by aging internal parts or assembly issues, like bearing looseness, which is common in this Wuling model. My advice is to stop and check the oil quality as soon as you hear any noise—use the dipstick to check the oil color; if it's cloudy, it's time for a change. Don’t try to disassemble it yourself, as that could complicate the problem. Spending a few hundred to a thousand yuan on repairs is always better than letting it turn into a major issue. Sharing this experience is to help others avoid unnecessary trouble—safety and smooth driving come first.
