Steering Noise
　　1. Fault Symptoms. Excessive noise when the car turns.
　　2. Fault Causes. Loose transmission components in the mechanical steering system lead to excessive steering noise; damage or severe wear of the power steering pump; loose or slipping drive pulley of the power steering pump causing excessive noise; poor performance of the steering control valve; loose hose joints or ruptured hoses allowing air to enter the hydraulic system, causing excessive noise; clogged oil filter or excessive sediment in the hydraulic circuit.
　　3. Fault Diagnosis: When steering noise occurs, the following methods can be used for diagnosis:
　　(a) If there is a "click" sound when steering, it may be due to looseness in the steering column shaft joint, loose tie rod, or loose ball joint. The above components should be checked, and if necessary, tighten or replace damaged parts; if the steering column shaft swings severely, replace the steering column assembly; if the steering gear is installed too loosely, please tighten it; lubrication points at the joints should be lubricated as necessary.
　　(b) If there is a "click" sound during steering, and the noise is louder when the steering wheel turns from one extreme position to another, it may be caused by slipping of the power steering pump drive belt. At this time, check the tightness and wear of the drive belt, and if necessary, tighten or replace the drive belt.
　　(c) When the steering wheel is at the limit position or slowly turning to position, if the steering gear emits a severe "hissing" sound, it may be due to poor performance of the steering control valve. The control valve should be replaced for comparative inspection to determine the fault.
