When your power steering makes noise while turning, it often indicates an underlying issue with your vehicle’s steering system. Addressing these noises promptly can prevent more significant problems and ensure safe driving. Common causes include low power steering fluid, worn-out components, or air trapped in the system.

What Causes Power Steering Noise When Turning?

Low Power Steering Fluid

One of the most common reasons for power steering noise is low fluid levels. Power steering systems rely on hydraulic fluid to function smoothly. When fluid levels drop, air can enter the system, causing a whining or squealing noise.

• Check Fluid Levels: Regularly check your power steering fluid level. If low, refill with the appropriate type for your vehicle.
• Look for Leaks: Inspect for any leaks in the power steering system, which can lead to fluid loss.

Worn or Damaged Components

Over time, components like the power steering pump, belts, or hoses can wear out or become damaged, leading to noise.

• Inspect Belts: Check the condition of the serpentine belt. A loose or worn belt can cause a squealing noise.
• Examine Hoses: Look for cracks or leaks in hoses that could affect fluid flow.

Air in the Power Steering System

Air trapped in the power steering system can create a whining noise. This often occurs after a fluid change or if the system has been opened for repairs.

• Bleed the System: To remove air, follow the manufacturer’s instructions to bleed the power steering system.
• Monitor for Bubbles: After bleeding, ensure there are no bubbles in the fluid, which could indicate air is still present.

How to Diagnose Power Steering Noise

Diagnosing the source of power steering noise involves a few steps. Here’s a simple guide to help you identify the problem:

1. Listen for the Noise: Pay attention to when the noise occurs. Is it only when turning left, right, or both?
2. Check Fluid Levels: Ensure the power steering fluid is at the correct level.
3. Inspect for Leaks: Look under the vehicle and around the power steering components for any signs of fluid leaks.
4. Examine Belts and Hoses: Check for any visible damage or wear on belts and hoses.
5. Test the System: With the engine running, turn the steering wheel from lock to lock to see if the noise changes or persists.

How to Fix Power Steering Noise

Once you’ve identified the cause, you can take steps to fix the issue:

• Refill or Replace Fluid: If low fluid is the issue, refill it. If the fluid is dirty, consider a complete flush and replacement.
• Repair or Replace Components: Replace any worn or damaged belts, hoses, or other components.
• Bleed the System: If air is trapped, bleed the system to remove it.

Why Does My Power Steering Whine?

A whining noise in the power steering system usually indicates low fluid levels or air in the system. Check the fluid level and bleed the system if necessary.

Can I Drive with a Noisy Power Steering?

While it might be possible to drive with a noisy power steering system, it’s not advisable. The noise could indicate a problem that might lead to steering failure, posing a safety risk.

How Often Should I Check Power Steering Fluid?

Check your power steering fluid every month or as recommended in your vehicle’s owner manual. Regular checks help catch issues early.

What Happens If the Power Steering Fluid Is Too Low?

If the power steering fluid is too low, it can lead to increased steering effort, noise, and potential damage to the power steering pump.

How Much Does It Cost to Fix Power Steering Noise?

The cost to fix power steering noise depends on the issue. Simple fixes like fluid refills are inexpensive, while replacing components like the pump or hoses can be more costly.

Conclusion

Addressing power steering noise when turning is crucial for maintaining your vehicle’s safety and performance. By understanding the common causes and solutions, you can take proactive steps to resolve the issue. Regular maintenance, including checking fluid levels and inspecting components, can prevent these problems from occurring. If the noise persists despite these efforts, consider consulting a professional mechanic for a thorough inspection and repair.
