Craig, hope all is well with you. I followed your directions, with drag link on pitman arm. As you know, plenty of corrosion on the frame and steering gear. I don't know how you even got that broke loose at QZ when you adjusted! I worked the nut back out far enough to bottom the inside set screw down to bottom out, not much more than you had it, maybe 3/4' more than what you had set. Its as far as it will go, tighten the 3/4" nut back down. Did a test drive, my friend Tony drove it also, he thinks springs inside the steering box, that assist power steering in the box are weak. This causes slight lag if you call it that, +- 2" now. Driving you can actually feel the springs assist in steering. You would know more than I in this arena, what do you think? Is there a company by Coburg or trucking company, to replace steering box, pitman arm and drag link, the parts likely will need to be cut off the coach! Craig thanks again, you can call me if you want to chat. 708-580-5323.
