Think I have to revive this thread, I had all the ball joints changed, new axle U joints, new steering box, borgenson steering shaft on for four years, and had analignment done today. Steering wheel is straight, BUT it still steers 1 and 1/4 to the left and 1 and 3/4 to the right. If I center the box again, then the wheel will be 1/4 turn to the right at center. I don't understand this, I adjust the drag link, it moves the position of center of the box, pitman can only go on in four different positions because of indexes, steering shaft can only go on one way because of flat spot on input shaft. The set screw from the borgenson if I remember right, goes on the flat spot. So where do you suggest I go next?
