How do I properly maintain the 8 Series' steering system?

I recently purchased a BMW 8 Series and I want to make sure I am properly maintaining the steering system for optimal performance. What steps should I take to ensure the longevity of the steering components?

Regularly check and top off power steering fluid levels according to the owner's manual instructions.

Inspect steering components for any wear or damage and replace as needed. This includes tie rods, ball joints, and steering rack.

Go for a professional alignment periodically, especially after hitting potholes or curbs.
