What Causes the Abnormal Noise When Turning the Steering Wheel to Full Lock?
1 Answers
Steering wheel to full lock causes abnormal noise due to the power steering pump hitting the oil seal of the oil reservoir and the rubber sleeve of the steering gear. The steering wheel is mostly connected to the steering shaft via splines, and its function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Below are some common steering-related faults: 1. Steering wheel vibration: When driving at medium to high speeds, severe steering wheel vibration accompanied by periodic abnormal noises from the chassis may indicate that the balance of the steering transmission device is compromised, possibly due to excessive wear of the drive shaft and its spline shaft and sleeve. 2. Weak steering: Difficulty in steering, feeling heavy and laborious, may be caused by overly tight rolling bearings in various parts of the steering system, poor bearing lubrication, or tight or lack of lubrication in the ball joints of the tie rods.
