Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, fluid pump, clean rags.
Ensure the vehicle is on a level surface and the ignition is off.
Disconnect the 12V battery to avoid accidental short circuits.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the reservoir cap and check the fluid level against the dipstick.
If low, use the appropriate power steering fluid (refer to the owner's manual).
Fill to the recommended level and replace the cap securely.

3. Inspect for Leaks

Clean any visible areas around the power steering components.
Check hoses, fittings, and the pump for signs of fluid leakage.
If leaks are found, replace the damaged hose or component as necessary.

4. Test Power Steering Motor

Reconnect the 12V battery.
Start the vehicle and turn the steering wheel to check for the whining noise.
If the noise persists, use a multimeter to check the voltage at the power steering motor.
Replace the power steering motor if it is not receiving the correct voltage or is malfunctioning.

5. Inspect Steering Rack and Column

Raise the front of the vehicle using a jack and secure with jack stands.
Check the steering rack for any unusual play or damage.
Inspect the steering column and joints for wear.
Replace any worn or damaged components identified during inspection.
