Ensure that the tie rod ends are properly tightened to the manufacturer's specifications (torque values typically around 30-50 ft-lbs, but check the service manual).
Reconnect the steering column securely.

4. Reassembly and Fluid Refill

Reinstall the front wheels and lower the vehicle back to the ground.
Refill the power steering fluid reservoir with the recommended type of fluid (check the owner's manual for specifications).
