Back in the 50's when we had bad roads and sorry lubricants, overhauling steering boxes was a common thing. But its been a long time since I have done one. I think its very educational for anyone who has never been into a steering box all the way to someone who has done a lot of them. If I were to do a box, I would certainly follow this thing step by step. I didn't have the luxury of having a manual like this 50 something years ago. Even though it was copyrighted in 1952, I had never seen it before.
