What Causes Abnormal Noises from the Car Chassis?

1 Answers

Possible causes of abnormal noises from the car chassis are as follows: 1. Noises during vehicle startup are generally due to suspension system faults, or may be caused by loose or damaged engine mounts. 2. Noises during vehicle steering may be due to faults in the steering system or suspension system. During steering, the vehicle's tilt causes deformation in 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. Issues with the bearings connecting moving and stationary parts. If it's a bearing problem, the driver can identify it by applying slight braking; if the noise remains unchanged during uniform motion with braking, it indicates a bearing issue. 5. Noises during driving on poor road conditions are mostly due to suspension system problems, or may be caused by loose braking system components.

What does National 5 vehicle mean?

National 5 vehicles are those that comply with the National 5 emission standards, which is the fifth stage of China's pollutant emission standards for motor vehicles, referred to as "National 5 Standard". The National 5 Standard is equivalent to the fifth stage emission standard implemented in Europe. In accordance with the national action plan for air pollution prevention and control, it imposes more stringent restrictions on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. Compared to the National 4 Standard, the National 5 Standard can reduce nitrogen oxide emissions from light-duty vehicles by 25% and from heavy-duty vehicles by 43%. Based on the annual registration of approximately 350,000 motor vehicles in Shanghai, it is estimated that the annual increase in new vehicles could reduce nitrogen oxide emissions by about 1,000 tons per year.

Does Modifying the Steering Wheel Affect the Airbag?

Modifying the steering wheel does not affect the airbag. However, when removing it, the steering wheel must be centered, and the clock spring must be in the central position; otherwise, it may break, causing the airbag warning light to illuminate. The airbag control module is typically located in front of or beneath the gear shift lever. Areas marked with AIRBAG in the vehicle indicate the presence of an airbag. Use a diagnostic tool to check for faults in the airbag system and repair them based on the fault codes. If no faults are detected, the diagnostic tool can directly clear any existing faults. The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. In the event of a car collision, airbags can reduce head injuries by 25% and facial injuries by approximately 80%.
