What Causes Chassis Abnormal Noises?
1 Answers
Possible causes of abnormal noises from the car chassis: It could be due to misaligned engine mounting pads, causing certain components to resonate or vibrate during operation, leading to friction between adjacent parts. Of course, it's also possible that the noise is caused by damaged components. Below are specific reasons: Characteristics of disc brake abnormal noises: When the vehicle is driven at low speeds on a flat road surface, irregular intermittent abnormal noises are heard from the wheel axle area. This is caused by damage, deformation, or detachment of the disc brake's brake shoe support plate, vibration damping spring plate, or guide plate, which increases the gaps between the brake shoe and the brake caliper support frame, resulting in mutual collisions and noise. Deformed parts can be repaired at a service station, and detached parts should be replaced. Characteristics of front suspension ball joint abnormal noises: When the vehicle is driven in low gear on uneven road surfaces, continuous abnormal noises are heard from the front axle area. The worse the road quality, the louder the noise, and it intensifies with increased speed. This is due to an enlarged gap between the ball joint and its socket, causing severe looseness. Since the ball joint socket is a sealed structure and cannot be disassembled, the only solution in such cases is to replace it at a service station.
