Re: bumpsteer and related problems, looking for ideas
I rotated the steering box down a bit on mine. It workes great. If you look at the steering shaft coming down from the steering wheel, you'll see that the steering box is rotated up in the back. You can rotate it down quite a bit and improve the location of the pitman arm a lot. Just remove the bracket that holds the box and cut the shelf off it. Takes about 20 min with a hand hacksaw (yuck). Then locate the box where you want it and drill and weld in some tubing for the new hole locations. Doing this will absolutely require a steering box brace to the opposite framerail, because you've removed a portion of the factory box support. With the brace to the other frame rail, it's much stronger than stock.
I made this mod, and I have very little draglink angle, bumpsteer is almost non-existent, and that's with a 6.5" SOA and a stock pitman arm. I had to move the box anyway, because I pushed the axle forward a bit and the draglink overlapped the tie rod too much. Rotating the box down moved the pitman arm down and forward enough to solve all these problems.
I ended up having the steering shaft extend about 2 inches. It still has plenty of overlap. If you're body lifted, your experience may be different in this area.
Hope this helps!
