The same concept applies to independent suspension. Unless the length and position of the tie rods is approximately the same as the length of the lower control arm, as the suspension moves through jounce and rebound, bump steer will be induced. People who mismatch a rack & pinion steering gear and an independent suspension system can have the same, or worse problems with the vehicle self-steering as an altered ride height vehicle with a straight axle. The tie rod, steering knuckle, and lower control arm needs to form pretty much of a rectangle with the wheels pointed straight ahead, with the inner tie rod pivot and the lower control arm pivot in virtually the same position, side to side.
