Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; use a dipstick if applicable.
If low, top off with the manufacturer's recommended fluid (usually ATF or dedicated power steering fluid).
Replace the cap securely.

3. Check for Power Steering Leaks

Visually inspect hoses and connections for signs of wear or fluid leaks.
If leaks are found, replace damaged hoses or seals as necessary.

4. Inspect Wheel Bearings

Raise the front of the vehicle and secure it on jack stands.
Spin the wheels by hand to listen for any grinding noise.
Grasp the wheel at 12 and 6 o'clock positions and shake; any play indicates bearing wear.
If bearings are worn, remove the wheel assembly and replace the bearings.

5. Evaluate CV Joints

Check the CV boots for cracks or tears.
Inspect the CV joints for any signs of damage or excessive play.
Replace any damaged CV joints or boots as needed.

6. Reassemble and Test

Reinstall any components removed during inspection.
Lower the vehicle and reconnect the battery.
Perform a test drive to ensure the whining noise is resolved.
