My steering box has been leaking from the top seal since I bought the truck. In the winter it wasn't too bad but now that it's hot it's leaking more and getting fluid all over the leaf spring and tie rods.
Here's a few shots of the offender after a good scrub down and degreasing.
And now the new Red Head re-manufactured box from Wes @ Classic Heartbeat. I chose the quick ratio model.
Installation was fairly straight forward. I kept the box mounted very loosely until I got everything else hooked back up and then I tightened it down. I did break the PS Return hard line though as it was too corroded to spin. I recommend ordering a new set of hoses for when you do the box. To fill the box I filled the pump and then turned the steering wheel a few turns and it sucked the fluid into the box. Repeated 5-6 times and then did it with the engine running to bleed out the last of the bubbles.
The new box is nice with a much, much smaller dead spot in the center. Steering effort feels a little higher and that makes sense because if it's moving more distance with less steering wheel input it's going to take more effort.
