How to Solve the Abnormal Noise of Baojun 730 Shock Absorber?
2 Answers
Shock absorber abnormal noise is caused by shock absorber oil leakage or aging of the shock absorber top mount plane bearing. The specific reasons for shock absorber abnormal noise are as follows: Shock absorber oil leakage: When the shock absorber leaks oil, the inside of the shock absorber cylinder cannot be effectively lubricated, resulting in significant friction noise during operation. Shock absorber top mount plane bearing aging: The plane bearing is located in the engine compartment. Open the engine hood and press the car body to listen whether the abnormal noise comes from the shock absorber top mount. If so, it is likely that the plane bearing has aged. If the shock absorber spring is deformed or broken, the only solution is to replace the entire shock absorber spring.
I've personally experienced the issue of squeaking shock absorbers on the Baojun 730 several times. Driving on rough roads, I always heard creaking sounds, which was quite annoying. Later, I found out it was due to loose mounting bolts on the shock absorbers. Tightening them myself solved the noise problem. However, if the sound resembles metal grinding or knocking, it might indicate worn bearings or aged rubber bushings, requiring professional inspection and replacement at a repair shop. Don't skimp on this expense, as persistent noise can lead to unstable driving, especially during turns where loss of control becomes a risk. I recommend regular checks of the suspension system—cleaning dust and applying grease can extend its lifespan. The Baojun 730's shock absorbers are relatively prone to wear, making semi-annual chassis inspections essential. Always choose a reputable workshop and opt for genuine parts to ensure a one-time fix and avoid repeated repairs. Remember, safety comes first—address issues early to prevent bigger troubles.
