Is the play present at all steering wheel angles, or is it just when the wheels are not centered? There should be at least around 1 inch of play in the wheel when the wheels are turned and much less play when the wheels are centered. If the box itself has a significant amont of play (more than 1 inch) then it may need a slight adjustment.
