Any words of wisdom and advice is most welcome.

The worm gear bearing preload (the shaft where the steering wheel attaches) doesn't need to be adjusted very often. The sector gear adjustment needs to be tightened until there is just barely zero clearance as the gear passes the center point. I like to remove the drag link so the only thing that is moving is the Pitman arm, none of th eother steering linkage. Count the turns of the steering wheel stop to stop, and turn back exactly halfway. There should be a 10 inch-pound increase in turning torque at the steering wheel nut as the gear rolls over center, measured with a torque wrench. For instance, if it takes 7 in.-lb. to keep the steering wheel turning as it approaches the center point, it will rise to 17, then return to 7 after the center point passes. If the torque rises, then drops at the center, rises and drops again, the steering gear is worn out and cannot be adjusted.

If I`m understanding your explanation correctly if after adjusting the torque rises at the center and drops off towards the end of steering wheel travel then my gear is okay. If it rises then drops at center then rises again, then the gearbox needs a rebuild.
Thankyou

Otherwise, you will have to remove the grill. I have adjusted the steering box on both my Advance design trucks and on both it made a huge difference. It is worth the effort, most likely. Good Luck!

I did find noticible play where the cross shaft exits to the pitman and by the looks of the chisel marks I wasnt the first to work on the box. So I will remove and rebuild when I have a chance.
Not sure whether to pull the inner fender or grill just yet. But either method shouldnt be to hard as all that stuff was recently installed in last summer.
Thanks to all.
