That is true if you are worried about having the tie rod exactly parallel with the axle in the horizontal plane. Since being off angle in that plane does not contribute to bump steer..I have found that to be no big deal if it is not, even when it is WAY not, like one of mine.;D . My '72 MX racer has a normal-rotation 4x4 F-150 box (makes keeping spares easier..they take a thrashing) and stock axle location. On that, the box is moved back about 4" from the stock location and the pitman arm faces forward, of course, and the tie rod is no where near parallel to the axle in hoizontal plane,,is parallel to track bar in vertical plane ...but it works fine.
