Sub-steps:
1. If leaks are found, replace damaged hoses or seals.
2. For a faulty power steering pump, remove it:
  - Disconnect the power steering lines using a socket set.
  - Remove mounting bolts and lift the pump out.
3. Install the new pump:
  - Position the new pump and secure it with mounting bolts to the specified torque (check service manual for exact values).
  - Reconnect the power steering lines, ensuring not to overtighten.
4. If the rack and pinion is damaged, remove it:
  - Disconnect the steering linkage and any associated electrical connectors.
  - Remove mounting bolts and slide out the rack.
