If your car’s power steering pump is making a roaring noise, it could indicate a problem that needs attention. This sound often arises from issues such as a low power steering fluid level, air in the system, or a failing pump. Addressing these problems promptly can help prevent further damage and ensure smooth steering.

What Causes a Power Steering Pump to Make a Roaring Noise?

Low Power Steering Fluid

One of the most common causes of a roaring noise from the power steering pump is low power steering fluid. When the fluid level is insufficient, the pump may draw in air, leading to noisy operation. To check this, locate the power steering reservoir and inspect the fluid level. If it’s low, top it up with the recommended fluid type for your vehicle.

Air in the Power Steering System

Air trapped in the power steering system can also cause a roaring noise. This often happens if the system has been serviced recently or if there is a leak allowing air to enter. To resolve this, the system needs to be bled to remove the air bubbles. This process typically involves turning the steering wheel fully left and right several times with the engine running, ensuring the fluid level remains adequate.

Failing Power Steering Pump

A failing power steering pump can produce a roaring or whining noise, especially when turning the wheel. Over time, internal components of the pump may wear out, leading to decreased performance and increased noise. If topping up the fluid and bleeding the system do not resolve the noise, the pump may need to be inspected by a professional mechanic.

How to Diagnose the Problem

Visual Inspection

• Check for Leaks: Look for signs of power steering fluid leaks around the pump, hoses, and reservoir.
• Inspect the Fluid: Examine the fluid for contamination or discoloration, which can indicate internal wear or a need for a fluid change.

Listen for the Noise

• Engine Off: With the engine off, turn the steering wheel to see if the noise persists. If it does, the issue might be mechanical.
• Engine On: Start the engine and listen for the noise while turning the wheel. A roaring noise with the engine on often points to the pump or fluid issues.

Professional Diagnostic Tools

If DIY methods don’t resolve the issue, consider consulting a professional who can use diagnostic tools to pinpoint the problem. They can perform pressure tests and inspect the pump’s internal components.

Preventive Measures for Power Steering Issues

Regular Maintenance

• Check Fluid Levels: Regularly check and maintain the power steering fluid level to prevent air from entering the system.
• Inspect for Leaks: Routinely inspect the power steering system for leaks and address them promptly.
• Fluid Replacement: Change the power steering fluid as recommended by your vehicle’s manufacturer to ensure optimal performance.

Use Quality Parts

Investing in quality replacement parts, such as hoses and pumps, can extend the life of your power steering system and reduce the likelihood of noise issues.
