8 Signs of a Failing Power Steering Pump and Replacement Cost


How Power Steering Pump Works?

Driven by a belt and pulley, the power steering pump operates with rotary vanes inside that rotate, extracting hydraulic fluid from the return line. The hydraulic fluid is then directed into the outlet, generating high pressure. The pressure level is determined by the engine speed, meaning that as the engine accelerates, the power steering pump moves more fluid. To manage excess fluid, a pressure relief valve facilitates its return to the pump.

Why Power Steering Pump is Important?

A power steering pump plays a crucial role in making driving more comfortable and less strenuous by assisting in the steering process. When this component begins to malfunction, it can lead to a range of issues affecting your vehicle's performance. Recognizing the symptoms of a bad power steering pump early on can save you from potential safety hazards and costly repairs.

Here are 8 signs to watch out for:

  1. Whining or Groaning Noises:

    When you hear a whining or groaning noise while turning the steering wheel, it often indicates a problem with the power steering pump. This noise is commonly associated with aeration or cavitation within the pump, meaning air is being introduced into the power steering fluid. Low fluid levels or a malfunctioning pump can contribute to this issue. If left unaddressed, it can lead to increased wear and tear on the pump components.

  1. Difficulty Turning the Steering Wheel:

    Difficulty in turning the steering wheel, especially at lower speeds or when parking, is a clear sign of power steering problems. The power steering pump assists in reducing the effort required to turn the wheel. If the pump is failing, you may experience increased resistance, making steering more challenging. This can pose safety risks, particularly in emergency situations where quick and precise steering is crucial.

  1. Fluid Leaks:

    Power steering fluid leaks are a visible indicator of potential pump issues. Leaks can occur at the pump itself or along the power steering lines. It's important to identify and repair leaks promptly, as low fluid levels can lead to pump damage and compromised steering performance. Regularly check under your vehicle for any signs of fluid accumulation.

  1. Foamy or Discolored Power Steering Fluid:

    Healthy power steering fluid is typically clear or has a reddish tint. If you observe foamy or discolored fluid when checking the power steering reservoir, it suggests the presence of air or contaminants. Air in the system can lead to diminished pump performance, while contaminants may accelerate wear on pump components. Regularly check and maintain the proper fluid level to ensure optimal power steering system function.

  1. Vibrations in the Steering Wheel:

    Vibrations or a jerky feeling in the steering wheel can result from irregular fluid flow within the power steering system. This inconsistency may be caused by a failing pump, leading to uneven steering. Addressing the issue promptly is crucial to prevent further damage to the pump and other steering components.

  1. Overheating Power Steering Fluid:

    Overheating of power steering fluid can occur when the pump is working harder than usual. This can lead to a burning smell, indicating potential damage to the pump and fluid breakdown. Overheating may be caused by low fluid levels, a failing pump, or problems with the power steering cooler. Continuous operation with overheated fluid can result in severe damage to the power steering system.

  1. Belt Squealing:

    The power steering pump is typically driven by a belt connected to the engine. If the belt is slipping, loose, or damaged, it can produce a high-pitched squealing noise. This noise is an audible signal that the belt is not effectively driving the pump, possibly due to wear or misalignment. A slipping belt can lead to decreased pump efficiency and should be addressed promptly to prevent further complications.

  1. Visible Wobbling in the Pulley:

    The power steering pump pulley should rotate smoothly without any wobbling or excessive movement. If there is visible wobbling, it may indicate a problem with the pulley itself or the pump's internal components. A loose or damaged pulley can lead to inefficiencies in the power steering system, affecting overall performance. Inspecting the pulley regularly as part of routine maintenance can help identify and address potential issues early on.
