What Causes the Noise from the Right Front Shock Absorber on Bumpy Roads?
2 Answers
Damaged shock absorber plane bearings or aged buffer rubber on the front wheel shock absorbers are common causes of the clunking noise when driving over bumps. Rubber Aging: The connection points between the shock absorber and the vehicle body are equipped with buffer rubber. Over time, rubber components can harden due to aging. When hardened rubber is compressed, it produces a clunking sound. To resolve this issue, simply replace the aged rubber on the shock absorber. Plastic Aging: There are two other possible causes: loose or excessively worn swing arm ball joints, which can create noise when the car goes over bumps; and aged plastic components, such as loose or excessively worn stabilizer bar bushings.
I encountered a similar issue just a few days ago. When driving over bumpy roads, there was always a creaking noise coming from the front right wheel, sounding like metal rubbing. This situation is mostly caused by a broken shock absorber or loose suspension components. Shock absorbers contain oil and pistons inside, and after several years of use, they are prone to oil leakage or rust, which can cause abnormal noises when driving over bumps. Additionally, problems with components like loose linkage screws or aged and cracked rubber bushings can also produce grinding noises on bumpy roads. I tried shaking the wheel slightly myself and felt some looseness, so I immediately went to a repair shop for inspection. After they replaced the shock absorber and buffer block, the noise disappeared. I suggest you not delay either; abnormal noises often indicate increased wear, and fixing them early can save you a lot of money. During regular maintenance, pay attention to checking suspension components and avoid driving aggressively on bad roads to extend their lifespan.
