What Causes Abnormal Noise in Shock Absorbers?
3 Answers
Abnormal noise in shock absorbers is caused by damage to the shock absorber. Here are specific details about the symptoms of shock absorber failure: Abnormal noise: If the shock absorber makes abnormal noises when the vehicle is driving on bumpy roads, it is highly likely that the shock absorber is damaged. Oil leakage: Use a flashlight to inspect the shock absorber through the wheel arch. If oil leakage is found on the exterior of the shock absorber, it indicates that the shock absorber is already damaged. Loose chassis: When driving on bumpy roads, if the vehicle body exhibits excessive bouncing and unstable swaying, it usually indicates a problem with the shock absorbers.
I've encountered quite a few cases of abnormal noises from shock absorbers, usually caused by aging shock absorbers or loose components. For example, when the oil inside the shock cylinder leaks out, internal friction can produce squeaking sounds; if the spring is broken or displaced, there will be a banging noise when going over bumps. Additionally, damaged bushings or ball joints in the suspension can creak when rusted. You can test by driving on bumpy roads to locate the source of the noise. I recommend promptly visiting a professional repair shop for inspection—don't delay, as suspension issues could lead to damage in other components and affect driving safety. Regular maintenance of the suspension system can prevent these problems, with checks recommended every six months. Moreover, overloading or taking sharp turns too quickly can also worsen the noises, so paying attention to driving habits is crucial.
I particularly enjoy discussing shock absorber noises, common issues include mismatched modified parts or sounds caused by daily wear and tear. For example, after raising the shock absorbers, the springs may become loose, producing squeaking sounds when driving over bumps; original shock absorbers may also make noises due to aging, oil leakage, or internal damage. For inspection, start with the simple things, like listening near the tire positions for the source. I believe that noises are not just annoying but also affect handling, and ignoring them can lead to faster wear of suspension components, potentially causing major issues. It's best to find a reliable mechanic to inspect the entire suspension system using a lift, including spring tension, etc. In daily driving, avoid rough roads to reduce impacts, which can prolong the life of the shock absorbers. A friend of mine spent a lot of money on repairs due to this issue, so addressing it early saves both money and hassle.
