Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Open the cap and check the fluid level; add appropriate power steering fluid if low.
If the fluid appears dirty or contaminated, proceed to flush the system.

3. Inspect and Replace Power Steering Pump (if necessary)

Remove Drive Belt:
- Use a socket set to remove the belt tensioner bolt and relieve tension.
- Slide the belt off the power steering pump pulley.
Remove Power Steering Pump:
- Disconnect the power steering lines from the pump using a wrench; be prepared for fluid spillage.
- Remove the mounting bolts securing the pump to the engine.
- Lift the pump out of the engine bay.
Install New Pump:
- Position the new power steering pump and secure it with mounting bolts (torque to manufacturer's specifications).
- Reconnect power steering lines ensuring tight seals.

4. Refill and Bleed Power Steering System

Fill the power steering reservoir with the appropriate fluid.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid level again and top off as necessary.

5. Reassemble and Test

Reinstall the drive belt and check for proper alignment.
Reconnect the battery.
Test drive the vehicle to confirm the whining noise has been resolved.
