What is the reason for the abnormal noise in the shock absorber spring of the Baojun 730?
3 Answers
Baojun 730 shock absorber spring abnormal noise causes and solutions are as follows: Shock absorber oil leakage: Caused by the shock absorber itself leaking oil or bending, check whether the shock absorber is leaking oil. Under conditions of no rain or car washing, directly observe the shock absorber housing or dust cover. It can be seen at a glance, very intuitive. Direct replacement is sufficient. Abnormal shock absorber pressure bearing: Caused by aging or abnormal wear of the shock absorber pressure bearing, direct replacement or lubrication is sufficient. Deformed shock absorber spring: Caused by deformation of the shock absorber spring, direct replacement is sufficient. Abnormal wheel bearing: It could also be abnormal noise from the wheel bearing, direct replacement is sufficient.
I've been repairing cars for many years, and the squeaking noise from the Baojun 730's springs is a common issue. It's often caused by the springs themselves aging, deforming, lacking sufficient elasticity, or becoming twisted, which leads to friction against the car body and produces creaking sounds while driving. Another frequent cause is loose or worn-out bushings or bolts connecting the shock absorbers, causing parts to rattle when driving on bumpy roads. Insufficient lubrication is also a key factor, especially in cold weather when the grease dries up, increasing friction between metal parts. The noise becomes more noticeable over time. I recommend promptly checking the condition of the springs, the tightness of the bolts, and the lubrication. Delaying repairs not only makes driving uncomfortable but also risks spring breakage, which could damage the chassis and increase repair costs. It's best to visit a professional shop for a comprehensive diagnosis and, while at it, service the suspension system to extend the car's lifespan and ensure a smoother ride.
My Baojun 730 started making squeaky noises from the springs after two years of driving, especially when going over speed bumps or rough roads - really annoying. Later, it was diagnosed as worn-out aging bushings in the spring connections. After replacing the parts, the noise disappeared completely. Possible causes include frequent driving on potholed roads accelerating wear, or insufficient factory lubrication. Since discovering this, I've become more cautious while driving, avoiding bad roads to prevent suspension damage. My advice - don't endure it, get it checked at a repair shop immediately. Spring noises affect ride comfort and distract drivers; if a spring breaks at highway speeds, it could be dangerous. Regular lubrication maintenance saves both money and hassle in the long run.
