5. Refill the power steering fluid.

4. Inspect and Replace Steering Rack (if needed)

Raise the vehicle and secure on jack stands.
Disconnect the steering shaft from the rack.

Disconnect the fluid lines from the rack and remove the mounting bolts.
Install the new steering rack by reversing the steps, ensuring proper alignment.

5. Final Checks

Reconnect the battery.
Start the engine and cycle the steering wheel to bleed air from the system.
Check fluid levels again and top off if necessary.
