Technician A says full time 4WD also allows the driver to select 2WD or 4WD. Technician B says part-time 4WD includes a differential or viscous coupling that allows the front and rear axles to rotate at different speeds. Which technician is correct?
A) Technician A only
B) Technician B only
C) Both Technicians A and B
D) Neither Technicians A nor B
Because full time 4WD does not allows the driver to select 2WD or 4WD. And part-time 4WD does not includes a differential or viscous coupling that allows the front and rear axles to rotate at different speeds.
