Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Inspect and Fill Power Steering Fluid

Locate the power steering fluid reservoir.
Using a clean rag, wipe the cap and remove it.
Check the fluid level against the dipstick and fill with the recommended power steering fluid if low.
Reinstall the cap securely after filling.

3. Check for Leaks

Inspect hoses and connections for signs of fluid leakage.
If leaks are found, replace the damaged hoses or fittings.
Tighten any loose connections as necessary.

4. Examine Steering and Suspension Components

Raise the front of the vehicle using a jack and secure with jack stands.
Inspect the steering rack, tie rods, and control arms for any signs of wear or damage.
Replace any worn or damaged components with OEM parts.

5. Test the Power Steering Pump

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock to listen for unusual noises.
If grinding persists, the power steering pump may need replacement.

6. Road Test and Final Inspection

Lower the vehicle and take it for a test drive to ensure the grinding noise is resolved.
Re-inspect the power steering fluid level after the test drive to check for leaks.
