Brian,
My coach was bad, but not that bad.
I took it to a front end shop and they said I needed to spend a lot of money there. I went home and called Dave Lenzi. If I was going to spend money on parts, I wanted his.

Dave said "I know what is wrong.. The steering box is off center." He described the situation further and I listened (and save a lot of money).

The most important picture is in manual X7525 page 9-39 Figure 64. Make absolutely sure that the steering box is on center. It actually has an interference when it is truly on center (it gets tight).
When the steering box is on its high spot, carry that center up to the steering wheel.
When the wheel is straight ahead with the box on its high spot, Check that the relay lever and the idler arm are both square to the front sub frame. (if they are not, you need an adjustable drag link or to adjust the one you have.
Now, set the wheels to ahead and toe with the tie rods ONLY.

The above to me a day and an half to get right and my coach is an absolute please to drive. (When I get to - Mary likes it too much.) (Still Own Dave a good dinner some where.)

Matt
