There are alignment marks on the shaft and on the arm. There is also a bolt next to the shaft used for alignment. It takes a 'special tool' which is nothing more than a longer bolt with a point on the end. I picked up a longer bolt at Lowes or Home Depot and just screwed it in locking the internals.

Here's a link to a steering box overhaul page.

I'm going to attack the box on my 420SEL which is leaking badly.
