Answers.Body: <p>Look at the instructions for set 42048 Race Cart. It has rack and pinion steering without using a rack. It basically uses the same 2-long beam as you use on the servo, but uses it to push two pins with towball end either left or right. You can find the instructions online at LEGO.com.</p>

Answers.Text: Phil B. is correct. Using the rack and pinion will allow the steering mechanism on that particular lego piece will allow you to be able to get around obstacles that you need to pass.
