What Causes Abnormal Noises from the Car Chassis?
1 Answers
Possible causes of abnormal noises from the car chassis include: 1. Noises during vehicle startup are generally related to suspension system failures, or may be caused by loose or damaged engine mounts. 2. Noises during turning may indicate issues with the steering system or suspension system. During turning, the vehicle's tilt causes deformation of the suspension system, which also participates in the movement. 3. Noises during driving on good road conditions may be due to faults in the braking system components, such as loose or worn parts, out-of-round brake drums, or uneven brake discs. 4. Problems with the bearings connecting moving and stationary parts of the vehicle. If it's a bearing issue, the driver can identify it by lightly applying the brakes; if the noise remains unchanged when braking at a constant speed, it indicates a bearing problem. 5. Noises during driving on poor road conditions are mostly related to suspension system issues, but may also be caused by loose braking system components.
