4. Install the new power steering pump and torque the bolts to manufacturer specifications (usually around 15-20 ft-lbs).
5. Reconnect the power steering lines and ensure they are tight.

4. Inspect and Replace Steering Rack (if necessary)

Tools Required: Socket set, torque wrench, jack stands
Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the front wheels for better access to the steering components.
3. Disconnect the steering column from the steering rack.
