ABSTRACT:
A limited slip differential which is incorporated into a differential gear for driving one wheel and the other wheel of a vehicle is inspected as follows. One wheel and the other wheel are mounted on one roll and on another roll, respectively. Acceleration of the vehicle is performed while the aforementioned one roll on which the aforementioned one wheel is mounted is being subjected to a force of restraining the rotation of the aforementioned one roll. A difference in rotational speed between the aforementioned one roll and the aforementioned another roll on which the other wheel is mounted is measured during the accelerating operation. A torque which operates on the aforementioned one roll is measured. A limited slip differential torque which is generated by the limited slip differential is measured from the measured torque. That standard value of the limited slip differential torque which is generated at the measured difference in rotational speed and the obtained limited slip differential torque are compared to judge whether the limited slip differential is acceptable or not.
