What causes the abnormal noise in the suspension of Wuling Hongguang Mini?
2 Answers
The abnormal noise in the suspension of Wuling Hongguang Mini is caused by oil leakage in the shock absorber, aging or lack of lubrication in the top seat plane bearing of the shock absorber, or deformation or breakage of the shock absorber spring. Below are the related explanations: 1. Oil leakage in the shock absorber: When there is oil leakage, the shock absorber cylinder cannot be effectively lubricated, resulting in significant friction noise during operation. 2. Aging or lack of lubrication in the top seat plane bearing of the shock absorber: The plane bearing is located in the engine compartment. Open the hood and press down on the body to check if the noise is coming from the top seat of the shock absorber. It is likely due to aging of the plane bearing. 3. Deformation or breakage of the shock absorber spring: In such cases, the entire shock absorber spring needs to be replaced.
I've been driving the Wuling Hongguang Mini, and suspension noise is quite common. Most of the time, it's due to the aging or leaking oil seals inside the shock absorbers, causing squeaking or thudding sounds when driving on bumpy roads. The bolts in the suspension system can also loosen, especially noticeable during frequent stops and starts in the city. Another reason is the wear and tear of the suspension rubber bushings—over time, they can crack, leading to direct metal-on-metal friction. If not addressed in time, the noise will only get worse, and it might even affect steering control. I recommend taking it to a reputable repair shop for a check-up. Replacing parts isn’t expensive, especially since Wuling parts are quite affordable. Regular maintenance is key—avoid rough roads to extend their lifespan. Microcars have simple designs, so regular upkeep is crucial. Don’t wait until a major issue arises to regret it.
