What Causes a Thud Sound When Driving Over Uneven Roads?

[NicoleRose]

If your car makes abnormal noises when driving over uneven roads, it may indicate a faulty shock absorber. The solution is to replace it with a new one. Alternatively, the issue could stem from a damaged shock absorber top mount rubber, which requires replacing the aged buffer rubber with a new one. More details are as follows: 1. The connection points between the car's shock absorbers and the body are equipped with buffer rubbers, which are rubber components. Over time, these rubber parts can harden and age, leading to abnormal noises when traversing bumpy roads. 2. Shock absorbers are considered wear-and-tear parts in vehicles, though they typically last a long time. Eventually, they may develop oil leaks, necessitating replacement. 3. When purchasing shock absorbers, opt for original equipment manufacturer (OEM) parts rather than those from smaller manufacturers, as OEM parts offer more stable and reliable quality. 4. To protect your vehicle, reduce speed when driving over bumpy roads or speed bumps. Additionally, ensure both wheels cross speed bumps almost simultaneously to minimize impact on the shock absorbers and suspension.
