Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and inspect fluid level; top off with manufacturer-recommended fluid if low.
Check the fluid condition; if it's dirty or has debris, consider flushing the system.

3. Inspect and Replace Components

Steering Linkage:
- Remove any protective covers or shields.
- Inspect tie rods and steering rack for wear; replace if necessary.
Wheel Bearings:
- Lift the vehicle and secure it on jack stands.
- Spin the wheels by hand to listen for grinding or roughness; replace bearings if noise is present.
CV Joints:
- Inspect the boots for tears; replace any damaged CV joints.

4. Reassemble and Test

Reassemble any components that were removed.
Reconnect the battery and ensure all tools are removed from the engine bay.
Test drive the vehicle to ensure the whining noise has been resolved.
