5. Reattach the new hoses and secure with clamps, tightening them to the manufacturer's specified torque value.

3. Check and Replace Power Steering Pump (if necessary)

Tools Required: Socket set, fluid catch pan
Instructions:
1. Locate the power steering pump, which is typically mounted near the engine.
2. Disconnect any electrical connectors and hoses attached to the pump.
3. Remove the mounting bolts using the socket set and carefully lift the pump out of its mounting position.
4. Inspect the pump for signs of leakage. If damaged, replace it with a new pump.
5. Install the new pump by reversing the removal steps, ensuring all connections are secure.

4. Inspect and Replace Steering Rack (if necessary)

Tools Required: Socket set, fluid catch pan, torque wrench
Instructions:
