if you look at the rack and tie rods, with the truck at ride height and wheels pointing straight ahead, the inner tie rod pivot points should be within an imaginary line drawn between the upper and lower control arm inner pivot points, within reason. the lower control arms should be relatively level as well. if the tie rod pivots don't match up relatively close to the control arm pivots then you will experience bump steer because they won't travel in the same arc as the control arms so they effectively get longer or shorter compared to the outer end of the tie rod as the wheel moves up and down.
possibly TCI could come up with the specs to adjust the steering on your model. also, if you sent them a few pics, they could possibly tell you if there is an assembly error.
