Rebuilt steering box adjustment

[carguy11089]

Hey, new here and I have a 2002 Chevy silverado 2500HD 4wd 6.0. I pulled the box due to leaking. Tore it down and replaced every seal; slowly and methodically. Truck is now back together. When bleeding, the box accepted some fluid and then began pushing back out with foam-looking liquid. Where is a good starting point for the adjusting nut on top and what else should i be looking for?

First saginaw style box.

Thanks in advance, Mat

Anyone?

Anyone, have an idea? Im assuming that the fluid is coming back out of the pump because of the air in the box. Any insight into that?
