Solution

1. Preparation

Gather tools: socket set, wrench set, jack, jack stands, multimeter.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level.
If low, top off with the manufacturer-recommended power steering fluid.
Check the fluid condition; if dark or contaminated, consider a fluid change.

3. Check for Leaks

Visually inspect the power steering hoses and connections for signs of fluid leakage.
If leaks are found, replace the affected hoses or connections.

4. Inspect Steering Components

Lift the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels to access steering components.
Inspect the tie rod ends and ball joints for play or damage; replace if necessary.

5. Evaluate Wheel Bearings

Rotate each front wheel by hand and listen for grinding noises.
If noise is present, replace the wheel bearings as needed.

6. Reassemble and Test

Reinstall the front wheels and lower the vehicle.
Test drive the vehicle to confirm the grinding noise is resolved.
