If you hear a squealing noise when turning the steering wheel, it usually indicates an issue with the power steering system or drive belt. While sometimes it’s just a loose or worn belt, squealing can also signal low power steering fluid or failing components. Ignoring it can lead to steering difficulties and more expensive repairs.

What does it mean if your steering squeals?

Squealing when steering typically means the power steering pump or drive belt is under strain. This happens if the belt is slipping, the pump is failing, or the fluid level is too low.

Common causes of squealing noise when turning

• Loose, worn, or slipping drive/serpentine belt
• Low or leaking power steering fluid
• Failing power steering pump
• Worn belt tensioner or pulley
• Contaminated or old power steering fluid

Why do you need to fix this problem quickly?

Left unchecked, squealing may turn into a complete loss of power steering, making the vehicle much harder to control. It can also cause the belt to snap, which may affect other systems like the alternator or water pump.

How do you know when to get it checked?

You should book an inspection if:

• The squealing happens whenever you turn the wheel
• The noise is worse at low speeds or when parking
• The steering feels heavy, jerky, or inconsistent
• You notice fluid leaks under the vehicle
• The squeal continues even after topping up fluid

What happens during an assessment?

A mechanic will:

1. Check power steering fluid levels and condition
2. Inspect the drive/serpentine belt for wear or slippage
3. Examine the belt tensioner and pulleys
4. Test the power steering pump for proper operation
5. Check for leaks in hoses and connections
6. Advise on necessary repairs such as fluid flush, belt replacement, or pump replacement

How much does it cost to fix?

Costs vary by cause. A power steering fluid top-up may cost $80–$150. Belt replacement typically costs $180–$350. Power steering pump replacement can range from $500–$1,200+.

Is it unsafe to drive with squealing when steering?

Yes. A failing power steering system can lead to sudden loss of steering assistance, making the car harder to control, especially at low speeds. The issue should be fixed promptly.
