What Causes Abnormal Noise from Front Wheels on Uneven Roads?
2 Answers
Abnormal noise from the front wheels when driving on uneven roads is mainly due to faults in the car's chassis. The specific reasons include the following 4 points: 1. Damping rubber aging: The connection points between the shock absorber and the car body are cushioned with rubber, which hardens and ages over time; when this hardened rubber is compressed, it produces abnormal noise. 2. Excessive play in the suspension arm ball joint: If the lower suspension arm ball joint becomes loose with excessive play, abnormal noise will occur when the car bumps. 3. Aging plastic components: The anti-roll bar bushings become loose with excessive play. 4. Damaged shock absorber: If the car is used in poor conditions or subjected to aggressive driving, the shock absorber may inevitably become damaged or start leaking oil.
I've noticed that front wheel noise on uneven roads is often related to chassis suspension issues, such as worn ball joints. When metal components develop excessive clearance, the clunking sound becomes more noticeable over bumps. This is a common situation I encounter when repairing cars, especially those that are four or five years old. After the rubber in the ball joints deteriorates and loses its lubricating function, it produces a rattling noise when driving over potholes. Additionally, a damaged shock absorber top mount can also cause such noises because the shock absorber fails to properly absorb vibrations, leading to the spring rebounding and hitting other body components, creating noise. Loose bushings in the tie rods are another possible cause, with the noise becoming more pronounced when turning the steering wheel. I recommend regularly inspecting these components and changing the lubricant periodically to prevent premature wear. If the noise persists, it's best to visit a repair shop as soon as possible for a professional inspection using specialized tools. This helps avoid minor issues escalating into major repairs, which could affect driving comfort and safety.
