Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir and remove the cap.
Use a dipstick or clean cloth to check the fluid level.
If low, add the recommended power steering fluid until it reaches the correct level.
Replace the cap securely.

Using a socket set, remove any clamps securing the hoses.
Carefully disconnect the hoses from the power steering pump and the steering rack.
Replace with new hoses, ensuring a proper fit and secure connection.
Reattach clamps and verify there are no leaks.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt using a belt tensioner tool.
Disconnect the power steering pump from its mounting brackets.
Remove the pump from the vehicle, taking note of how it is connected.
Install the new power steering pump in reverse order, ensuring all connections are secure.
Reinstall the serpentine belt and ensure proper tension.

5. Bleed the Power Steering System

Fill the power steering reservoir to the proper level.
Start the engine and turn the steering wheel fully left and right several times to expel air from the system.
Check fluid level again and top off if necessary.
