Remove the serpentine belt from the power steering pump.
Disconnect the power steering lines from the pump using the appropriate wrench.
Unbolt the pump from its mounting bracket and remove it from the vehicle.
Install the new power steering pump by reversing the removal steps and torqueing the bolts to the manufacturer’s specification.

5. Inspect and Replace Steering Rack (if necessary)

If the steering rack is found faulty, disconnect the battery again.
Remove the tie rod ends from the steering rack.
Disconnect any electrical connectors and hoses leading to the rack.
Unbolt the steering rack from its mounting points and remove it.
Install the new steering rack and reconnect all components, ensuring proper alignment.

6. Final Steps

Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock to bleed the system of air.
Check for leaks around the pump, hoses, and steering rack.
