- If noisy, remove the pump by:
  - Disconnecting the power steering lines.
  - Unbolting the pump from its bracket.
- Replace the pump with a new unit if necessary, ensuring proper alignment.

5. Inspect Steering Rack

Sub-steps:
- Check the steering rack for any signs of leaking or damage.
- If damage is present, remove the steering rack:
  - Disconnect the tie rod ends.
  - Unbolt the rack from the chassis.
  - Replace with a new steering rack and reassemble.

6. Reassemble and Test
