Final answer:
Technician A is incorrect; positive toe actually means the fronts of tires are closer together than the rears. Technician B is correct; a ball joint in a MacPherson strut is typically a follower, not a loaded joint.
Step-by-step explanation:
The accuracy of both technicians' statements can be assessed separately. First, Technician A states that positive toe is when the fronts of the tires are farther apart than the rears of the tires. This statement is incorrect. Positive toe, also known as toe-in, is the condition where the front edges of a pair of tires are closer together than the rear edges. Thus, Technician A is not correct.
Second, Technician B states that a ball joint in a MacPherson strut suspension is a follower joint and not loaded. This is generally true. The ball joint in a MacPherson strut system typically serves as a pivot point for steering and does not carry the vehicle's weight; instead, the strut itself bears the load. Therefore, Technician B is correct.
The correct answer to which technician made a true statement would be B, Technician B only.
