Ensure the vehicle is parked on a level surface and securely lifted (if necessary).
Disconnect the negative battery terminal for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level, ensuring it meets the "full" mark.
If low, add the recommended power steering fluid type as specified in the owner's manual.
Recheck for leaks after filling.

Tools Required: Socket set, wrench set, fluid catch pan
Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering pump from the hoses, using a fluid catch pan to collect any spilled fluid.
Unbolt the power steering pump from its mounting bracket.
Install the new power steering pump by reversing the removal steps, ensuring all connections are tight.

4. Check Steering Components

Inspect the steering linkage for any signs of wear or damage, such as loose or worn tie rods.
Replace any damaged components as necessary.
Tighten any loose bolts and ensure proper alignment.

5. Test Drive and Final Checks

Reconnect the negative battery terminal.
Start the engine and turn the steering wheel from lock to lock to bleed air out of the system.
Test drive the vehicle to ensure the whining noise is resolved.
