What Causes the Abnormal Noise When a Car Runs Over a Stone?

[LondonRose]

If a loud noise occurs, it may be due to the stone hitting the chassis, the sound from the lower control arm of the suspension, or the noise from the shock absorber. If you encounter this situation, it is recommended to have the chassis inspected. Here are some additional details: 1. Shock Absorber: The shock absorber in a car is a wear-prone component. Generally, shock absorbers can last a long time, but their performance deteriorates with prolonged use. If a loud abnormal noise occurs after running over a large stone, it might be coming from the shock absorber. In some cars, shock absorbers may also develop oil leaks over time. 2. Avoiding Bumpy Roads: When driving, try to avoid deep potholes, and always slow down when passing over bumpy roads or speed bumps. This helps reduce the impact on the suspension system. Driving on bumpy roads or over speed bumps may alter the car's wheel alignment data, so it's important to have regular wheel alignments. Incorrect wheel alignment data can lead to uneven tire wear or the car pulling to one side.
