Everett,
My power steering box was leaking from the top "O" ring. I was able to loosen the cap, change the "O" ring and tighten it back up without removing it form the car. It sounds like this advise might be too little to late. If you are looking for documentation I would suggest the Big Blue Book, BBB. It is the factory repair manual. I would suggest that you can purchase the cd-rom version of the book from the MB Classic Center.
Good luck,
Ted
