2. Disconnect any electrical connectors and the power steering lines from the steering rack.
3. Unbolt the steering rack from its mounts and carefully remove it from the vehicle.
4. Install the new steering rack in reverse order of removal, ensuring all bolts are torqued to manufacturer specifications (refer to repair manual for specific torque values).

5. Refill Power Steering Fluid

Sub-steps:
1. Fill the power steering reservoir with the recommended fluid type (typically ATF or PS fluid).
2. Start the engine and turn the steering wheel from lock to lock to remove air bubbles.
3. Check fluid levels again and add more if necessary.
