Solution

1. Preparation

Gather tools and parts before starting.
Ensure the engine is off and cool. Disconnect the battery for safety.
Tools required: Socket set, wrench set, power steering fluid, funnel, multimeter.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, use a funnel to add the recommended type of power steering fluid (refer to the owner’s manual).
Replace the cap securely.

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

If the noise persists, remove the drive belt by loosening the tensioner pulley.
Disconnect the power steering pump from the mounting brackets using a socket set.
Carefully detach the inlet and outlet hoses from the pump, using a container to catch any fluid.
Install the new power steering pump by reversing the removal steps:
- Attach the hoses to the new pump, ensuring they are secure.
- Bolt the pump back into the mounting brackets.
Reinstall the drive belt, ensuring proper tension.

4. Bleed the Power Steering System

With the engine off, fill the power steering reservoir to the proper level.
Start the engine and turn the steering wheel from lock to lock several times to help remove air from the system.
Check fluid level again, topping off if necessary.
Inspect for any leaks around the new pump and connections.
