Sub-steps:
1. Remove any components obstructing access to the power steering pump (e.g., belts, brackets).
2. Disconnect the power steering hoses from the pump using a wrench.
3. Unbolt the pump from its mounting location using a socket set.
4. Install the new pump in reverse order, ensuring all connections are secure.
5. Refill the power steering fluid and check for leaks.

4. Inspect and Replace Steering Rack

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Disconnect the steering shaft from the steering rack.
3. Remove the mounting bolts securing the steering rack.
4. Disconnect the power steering hoses and carefully remove the old steering rack.
5. Install the new steering rack, reconnect hoses, and secure bolts to specified torque values.
