The power steering pump is a core component of the hydraulic assist era, and its reliability is crucial. If unusual noises or heavy steering occur, immediate maintenance is required, otherwise it may lead to more expensive repairs such as damage to the steering mechanism.

During regular maintenance, pay attention to oil level and quality, and address any signs of failure promptly. When replacing, choose a high-quality, perfectly matched steering pump, and ensure system cleaning and purging, which is the fundamental guarantee for restoring light steering feel and safe driving.

Common faults:

• Internal wear: Wear of precision components such as blades, pressure plates, and stator rings leads to insufficient pump oil pressure.
• Oil seal leakage: The aging of the shaft head oil seal is the most common cause of oil leakage.
• Bearing damage: Bearing wear in the pump causes abnormal noise and jamming.
• Control valve failure: Jamming of flow control valves or pressure valves results in abnormal pressure.

Symptoms of faults:

• Heavy steering: The power assist becomes significantly worse, making it difficult to turn the wheel.
• Abnormal noise: The most common symptom. It produces a "buzzing," "squeaking," or "clacking" noise when turning the wheel, with the noise increasing as the engine speed rises.
• Oil leakage: Red or brown power steering fluid seepage from the pump body or joints.
• Steering wheel vibration: Unstable power assist pressure causes the steering wheel to vibrate at specific speeds or angles.
