The cpp 400 box has a adjustment screw.
See how much slop is in the steering wheel before pitman arm moves as you move it back and forth. From the factory it was way off and had a lot of slop just in the steering box itself. we made it adjusted and that help greatly with the track. NOTE too tight and it will not return to center when you let go of wheel. you want to find the sweet spot between slop and steering wheel return.
Second. the rag joint can have some play as well. we had one that was new but the rubber was really soft and gave for more slop. its amazing how much 1 mm plays will affect a large steering wheel.
Third: you have a shorter drag link due to 4x3 vs stock straight axle and earlier years. The more its not parallel to the ground / frame the more its going to have impact on pot hole and bumps in road will have a large effect since its shorter.
