What Are the Common Faults in Automotive Steering Systems?

[GabrielleLee]

Common faults in automotive steering systems include heavy steering, one-sided heaviness, abnormal noises, oil leaks, steering wheel vibration, poor stability, and weak steering wheel returnability. Oil leakage in the steering gear is typically caused by aging or damaged oil seals inside the chamber, leading to poor sealing and seepage of steering fluid. External oil leaks from the steering gear usually occur at a few specific locations: the upper cover of the steering gear, the side end cover, and the connection point of the steering shaft arm. These areas are equipped with sealing rings, and replacing the oil seals and sealing rings can resolve the issue. The causes of abnormal noises in the steering system include: 1. Overloading of the steering system, causing excessive wear of the stator and rotor inside the steering pump, which leads to irregular movement of the fluid inside the pump and produces abnormal noises; 2. Loose installation of the steering gear or steering pump on the bracket, internal wear of the steering gear, and improper adjustment of the gears and rack.
