What Causes the Abnormal Noise When a Car Passes Over Bumpy Roads?

[DeAriel]

Here are the specific reasons for abnormal noise when a car passes over bumpy roads: 1. Shock absorber failure: Inspect the car's shock absorbers. It's best to go to a 4S shop or repair shop and use a lift to raise the vehicle to check for gaps in the shock absorbers or any faults in the suspension. If the shock absorber is leaking oil, it might be due to a faulty oil seal gasket, requiring the shock absorber to be replaced. Generally, the service life of a shock absorber is 80,000 to 100,000 kilometers. When the car has traveled 80,000 kilometers, you can ask the technician to pay attention to the condition of the shock absorbers during regular maintenance and repair any faults promptly. 2. Excessive clearance in the steering tie rod ball joint: There may also be abnormal noise when turning. In severe cases, symptoms like steering wheel vibration and tire wear may occur. The ball joint should be replaced at a 4S shop or repair shop promptly. 3. Excessive clearance in the lower control arm or loose lower control arm: The lower control arm is an important component that maintains the elasticity of the car body and is part of the car's suspension. It connects the axle and the frame, helping to cushion the impact of bumpy roads on the car. Once the lower control arm fails, it should be replaced at a 4S shop or repair shop immediately.
