Removing the power steering box on a Wrangler? What do I need to know?

The power steering box where the pitman arm attaches (not the pump) is leaking more fluid than a new born baby. It looks like it's coming from the seal where the steering shaft enters the box at the top. I can't tell for sure though and either way I need to remove it from the Jeep to check it out and replace parts or the whole unit if necessary. When removing a power steering box is there anything that needs to be kept in perfect alignment? Do I need to take note of the position of the steering shaft and pitman arm?
