What Causes Abnormal Noises from the Car Chassis?
2 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.
I've been driving for over a decade, and the sound of chassis noise always gives me a headache. It's mostly suspension system issues, like worn-out shock absorbers or cracked springs, making creaking noises on bumpy roads. It could also be loose chassis bolts, causing clunking sounds during high-speed turns. My old car had this problem, and it turned out to be worn steering linkage, making it unstable at high speeds. Remember to pay attention to when the noise occurs, like during startup or stopping, as it can help pinpoint the root cause. Don't try to fix it yourself—it's best to take it to a repair shop for a thorough inspection of the suspension and steering components to avoid small issues turning into major accidents.
