1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Power Steering Fluid Inspection

Locate the power steering fluid reservoir.
Remove the cap and visually inspect the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended power steering fluid (refer to the owner's manual).

3. Inspect Steering Components

Visually examine the power steering pump, hoses, and rack for leaks or damage.
Check the belt driving the power steering pump for wear and proper tension.
If any components are damaged, replace them as necessary.

4. Tire and Wheel Inspection

Remove the front wheels using a socket set.
Inspect the tires for uneven wear patterns or bulges.
Rotate or replace tires if necessary to ensure even contact and wear.

5. Test Drive and Verification

Reassemble any components and reconnect the battery.
Perform a test drive to confirm that the whining noise has been eliminated.
Listen for any residual noise during turns.
