my Volvo XC90 makes a grinding noise when I turn the steering wheel what's wrong

Solution

1. Preparation

• Gather tools: socket set, torque wrench, power steering fluid, cleaning cloths, and safety gloves.
• Ensure the vehicle is parked on a level surface, and the engine is off.

2. Check and Replace Power Steering Fluid

• Locate the power steering reservoir and remove the cap.
• Check the fluid level; if low, add the appropriate power steering fluid as per the manufacturer’s specifications.
• If the fluid appears dark or contaminated, drain the old fluid using a siphon or turkey baster, then refill with new fluid.

3. Inspect and Replace Power Steering Components

• Check the power steering pump for leaks or noise. If defective, remove the pump by:
  • Disconnecting the power steering lines with a wrench.
  • Unbolting the pump from its bracket.
  • Installing a new power steering pump by reversing the steps.
• Inspect and replace any damaged hoses connected to the pump.

4. Inspect Steering Linkage

• Raise the front of the vehicle using jack stands for safety.
• Visually inspect tie rod ends and ball joints for play or wear.
• If any components are worn, replace them by:
  • Removing the old part using a socket and ratchet.
  • Installing the new part and torqueing to manufacturer specifications.

5. Reassemble and Lower the Vehicle

• Ensure all components are properly secured and reattach any covers removed during inspection.
• Lower the vehicle and perform a final check of the steering system.
