Just like on part-time 4WD vehicles, full-time 4WD and AWD have both a front and rear differential on the front and rear axles that allows the left and right wheels to move at different speeds when making a turn.
tulad ng sa part-time 4WD sasakyan, full-time 4WD at AWD ay may parehong isang harap at likod na kaugalian sa harap at likod axles na nagbibigay-daan sa kaliwa at kanang gulong upang ilipat sa iba’t ibang mga bilis kapag gumagawa ng isang turn.
