What Causes Power Steering Fluid Leak?
1 Answers
Power steering fluid leakage can be caused by: 1. Poor quality oil seals resulting in insufficient tightness between the seal and its cavity; 2. Deviation in concentricity between the worm gear housing hole and its oil seal seat, causing leakage at the pitman arm area; 3. Loose pitman shaft or out-of-round shaft diameter. The power steering mechanism assists drivers by reducing steering effort when turning the wheel, making driving more comfortable and convenient. Power steering systems are mainly categorized into rack-and-pinion steering and recirculating-ball steering. Currently, there are three common types of power steering systems: electric power steering (EPS), hydraulic rack-and-pinion steering, and electro-hydraulic power steering.
