Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery to prevent any electrical issues.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the appropriate fluid if low (refer to owner's manual for specifications).
Reattach the cap securely.

3. Inspect and Repair Leaks

Visually inspect all power steering hoses and connections for leaks.
If leaks are found, replace any damaged hoses or seals as necessary.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt by loosening the tensioner pulley.
Disconnect the power steering pump from the mounting brackets and remove the pump.
Install the new power steering pump and reconnect it to the mounting brackets.
Reattach the serpentine belt, ensuring proper alignment.

5. Bleed the Power Steering System

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