What are the causes of abnormal noises when a car travels on bumpy roads?

[DelBradley]

There are several reasons for abnormal noises when a car travels on bumpy roads: Abnormal noises from the braking system: Loose brake pads, brake calipers, or brackets; faulty brake pads or brake discs. Solution: Check if the braking system is loose and whether there is abnormal wear on the brake pads and brake discs. Abnormal noises caused by damaged ball joints, suspension, or connecting brackets: Faults caused by loose ball joints or aged and cracked rubber bushings after prolonged use. Solution: Replace the ball joints or support bushings with new ones. Possible failure of the steering gear: If the steering wheel is turned too sharply during normal driving, it places a greater load on the steering gear, leading to severe wear and resulting in abnormal noises. Solution: It is recommended to inspect and replace the relevant components.
