Why does the Wuling Hongguang mini make abnormal noises when running?
2 Answers
Wuling Hongguang mini makes abnormal noises when running due to friction between the shock absorber top screw and the vehicle body. The following are the inspection methods for automobile shock absorber faults: 1. Drive the car on a road with poor conditions for 10km and then stop. Touch the shock absorber housing with your hand. If it is not hot, it means there is no resistance inside the shock absorber, and the shock absorber is not working. At this time, you can add appropriate lubricating oil and test again. If the housing becomes hot, it means there is insufficient oil inside the shock absorber, and it should be filled up; otherwise, it means the shock absorber has failed. 2. Press the bumper hard and then release it. If the car jumps 2~3 times, it means the shock absorber is working well. 3. When the car is driving slowly and brakes suddenly, if the car vibrates violently, it means there is a problem with the shock absorber. 4. Remove the shock absorber and stand it upright, clamp the lower connecting ring on a bench vise, and pull and press the shock rod several times. At this time, there should be stable resistance. The resistance when pulling up should be greater than the resistance when pressing down. If the resistance is unstable or there is no resistance, it may be due to insufficient oil inside the shock absorber or damage to the valve parts, and repair or replacement of parts should be carried out.
As a long-time owner of the Wuling Hongguang Mini EV, I've found that when the car makes strange noises while driving, it's mostly related to the suspension system. It creaks and groans on uneven roads. The bolts on suspension arms or shock absorbers tend to loosen, especially after rain when there's more dust, making problems more likely. Aging rubber bushings in the chassis connections can also produce those clicking sounds, just like the ones I replaced during my last maintenance. Uneven tire wear or deformed wheel hubs cause whooshing noises during turns, while brake pads with trapped small stones or dust create sharp friction sounds. Although rare, a loose motor drive belt in an electric vehicle might produce a buzzing sound. Loose interior components like door pockets or unsecured seats rattle when going over bumps. I recommend parking and listening carefully to locate the source of the noise - for example, trying low-speed emergency braking can help quickly identify the issue. It's best to promptly visit a 4S shop to check the suspension and tighten any loose bolts. Don't wait for minor issues to become major problems - safety comes first, and only then can you drive with peace of mind.
