What Causes Abnormal Noise When Turning the Car?

[StPiper]

The causes of abnormal noise when turning the car: 1. Damage to the vehicle's steering gear, with internal gear mechanism failure; 2. Failure of the vehicle's suspension, such as loose shock absorber top rubber bearings or upper and lower control arm ball joints; 3. Abnormal noise from the wheel half-shaft CV joint, due to insufficient lubrication or damage inside the CV joint; 4. For mechanical hydraulic power steering, the noise may come from the power steering pump or belt. Generally, during turns, the system pressure is high, and the mechanical hydraulic power steering pump operates under heavy load, which can easily produce abnormal noise; 5. Loose steering gear fixing rubber sleeve or other loose parts, such as loose inner or outer ball joints of the steering gear. Steering wheel operation precautions: 1. Avoid turning the steering wheel while stationary; try to steer only after the vehicle starts moving. Stationary steering should only be used occasionally in special circumstances for maneuvering; 2. After the vehicle is parked, the steering wheel should be returned to the central position to avoid placing load on the suspension system and tires; 3. When making a U-turn, try to avoid turning the steering wheel to the extreme lock position.
