What Causes Abnormal Noises in the Car Chassis?

[OLeila]

Abnormal noises in the car chassis can be caused by the following reasons: 1. Suspension system: Noises heard when starting the vehicle are usually due to suspension system failures, which may be caused by loose or damaged engine mounts. 2. Steering and suspension systems: Noises during turning may indicate faults in the steering and suspension systems, as the vehicle tilts during turning, causing deformation in the suspension system and involving it in the motion. 3. Brake system components: Noises while driving on good road conditions may be due to faults in the brake system components, such as loose or worn parts, out-of-round brake drums, or uneven brake disc surfaces. 4. Bearings: It could also be an issue with the bearings that connect moving and stationary parts of the vehicle. If it's a bearing problem, the driver can identify it by lightly applying the brakes. If the noise remains unchanged when the vehicle is moving at a constant speed with brakes applied, then it is likely a bearing issue.
