Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the ignition is off.
Disconnect the battery to prevent accidental electrical shorts.

2. Check Power Steering Fluid

Remove the power steering fluid cap.
If the fluid is low, top it off with the recommended fluid type (check owner's manual for specifications).
Inspect the fluid for contamination (milky appearance or debris).

3. Repair or Replace Leaking Components

If leaks are found in hoses or seals, replace them:
- Hoses: Disconnect the hoses from the power steering pump and rack.
- Seals: Remove the old seals and install new ones.
- Tools Required: Wrench set, socket set, fluid catch pan.

4. Replace the Power Steering Pump (if necessary)

Disconnect the power steering pump from its bracket.
Remove the inlet and outlet hoses from the pump.
Install the new pump by reversing the removal steps.
Torque the pump mounting bolts to manufacturer's specifications (usually around 20-30 Nm).

5. Flush the Power Steering System

If fluid was contaminated, flush the system:
- Disconnect the return line from the pump.
- Use a fluid pump to cycle new fluid through the system until it runs clear.
- Reconnect the return line securely.

6. Reassemble and Test

Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.
Check for any leaks and ensure the whining noise has been resolved.
