Manual steering box question

Worn and readjusted ones are tight at both ends of the travel instead of the middle in my experience.
If you do adjust one or both you want to back off the locknut and turn the center bolt in just till it has resistance then hold the center bolt and lock the nut back down.
I normally turn it back and forth a little as I tighten the center bolt just to be sure things are settled in all the way.
