Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering pump from its mounting bracket.
Remove the inlet and outlet lines from the pump, ensuring to catch any fluid that may leak.
Install the new power steering pump by reversing the removal steps and torque bolts to manufacturer specifications (typically 18-25 Nm).
Reinstall the serpentine belt, ensuring proper routing.

Slide the old steering rack out and install the new one by reversing the removal steps.
Ensure all components are tightened to the correct torque specifications.

5. Bleed the Power Steering System

With the engine running, turn the steering wheel from lock to lock to remove any air trapped in the system.
Check the fluid level in the reservoir and add more fluid if necessary.
