why does my Volvo XC90 make a squealing noise when I turn the wheel

Solution

1. Preparation

• Gather tools: socket set, torque wrench, power steering fluid, serpentine belt tool, and flashlight.
• Ensure the vehicle is parked on a level surface with the engine off.

2. Check Power Steering Fluid

• Open the hood and locate the power steering fluid reservoir.
• Remove the cap and check the fluid level. If low, top it off with the recommended type of power steering fluid.
• Inspect the fluid condition; if it's dark or has debris, consider flushing the system.

3. Inspect and Replace Serpentine Belt

• Use the serpentine belt tool to relieve tension on the belt.
• Remove the belt and inspect for cracks, fraying, or glazing.
• If damaged, replace the serpentine belt with a new one, ensuring proper routing and tension.

4. Examine Steering Components

• Check the power steering pump for leaks. If leaking, replace the pump.
• Inspect the steering rack and pinion for any abnormal wear or damage.
• Tighten any loose connections and replace worn components as necessary.

5. Suspension Check

• Lift the vehicle using a jack and secure it with jack stands.
• Inspect ball joints and tie rods for play or damage and replace if necessary.
• Reassemble any removed components securely and torque to specifications.
