New steering box question

[sigurd]

I put a rebuilt box on my 72k10 that I got from Napa. No problems with the install. I had just put a new pump and lines on it a few months ago so I figured I would do it all the way.

When I put the new box on and took it for a spin the steering was so hard it felt like I did not have power steering at all. My steering is more responsive, meaning when I turn the wheel left or right the tire move right away.

Now I know that there is at least one adjustment I can make on the box. If I loosen that locknut and back off that allen bolt, will that make the steering looser or less responsive when I turn left or right? In other words will backing off that allen bolt make it take more time untill the tires start moving when I turn the steering wheel?

Thanks for any advice.
