Straight axles and rack and pinion don't work together. With the rack centrally located, it and it's ends stay in one place as suspension travel happens. The axle is a different story, however, as it travels up and down, through each bump it moves a slight bit side to side and then creates bump steer, which is not only unsafe, but scary to drive. The long arms on our stock suspensions mostly eliminate this behavior.
