I had to pull the brake master cylinder this moring so I ecided to pop the little cover on the top of the steering box and have a look. There was a spring inside. The small cover had three very thin metal gaskets between it and the steering box. My questions is how is the box lubricated, how do I know if it needs more, where is it added and what is the lubricant? I have poored over this forum and through my Afa Bble and can't find this addressed anywhere. I have decided to ask the internet Alfa Oracle!
