The propeller shaft transfers rotational power from the gearbox to the differential in a rear axle setup.
The crown wheel and pinion gear redirect the drive by 90 degrees.
The differential then divides the engine torque into two outputs, enabling independent wheel rotation speeds.
This is crucial during turns, as the outer wheel covers more distance than the inner wheel.
While the axle shaft delivers power to the wheels, the torque splitting mechanism is located within the differential.
Consequently, differential is the accurate answer.
