During the lash inspection, what must be done to the front wheels?

Setting the front wheels straight ahead is essential during the lash inspection because it ensures that the measurement of the wheel play is accurate. When the wheels are aligned in a straight position, any excessive play or movement can be detected reliably. This position minimizes variables that could distort the results, allowing the inspector to adequately assess the condition of the steering components and other associated parts.

Turning the wheels left and right might introduce additional variables and could lead to inaccurate readings of any lash. Lifting the vehicle off the ground may not be necessary for this specific aspect of the inspection since the goal is to assess play under normal conditions. Checking tire pressure, while important for overall vehicle safety, is not directly related to the lash inspection focused on the wheel assembly's movement.
