Both technicians are correct. Technician A is correct in stating that many idler arms are allowed to have a slight amount of play, as this is part of their design to accommodate the movement of the steering system. Technician B is correct in stating that checking the play in idler arms requires applying a specific amount of force to the arm and measuring the movement with a dial indicator, as this is a standard procedure to accurately assess the condition of the idler arm.
