What Causes Abnormal Noises in a Car's Chassis?

[DelLeila]

Abnormal noises in a vehicle's chassis are mainly caused by faults such as loosening, wear, and failure of components in the steering system, suspension system, or braking system. Owners can visit a repair shop for inspection and handling. Below are the relevant details: Handling the fault: Inspect the area where the noise occurs based on the symptoms. Vehicle inspections are divided into static checks and dynamic checks. After parking the car, the wheels can be secured with triangular wooden blocks, focusing on checking the wear of needle bearings, rear axle bearings, and reducer bearings, as well as the tightness of various chassis components. Dynamic inspection of the noise involves determining the faulty area based on the pattern of the sound, with different parts requiring different repair methods. Cars are prone to abnormal noises: During prolonged operation, cars are subjected to various impact forces, which can cause wear or deformation of parts, leading to abnormal noises. Only by continuously accumulating experience in practice and understanding the patterns and characteristics of car noises can one accurately identify the source of the noise when it occurs and perform timely repairs.
