Quizplus · Accepted Answer

Technician A is correct because part-time four-wheel drive systems are designed to be used in off-road or slippery conditions only, to avoid drivetrain damage. Technician B is correct because full-time four-wheel-drive systems often use a center differential to allow for differences in wheel speed between the front and rear axles, which enables their use on all types of surfaces.
