A differential testing device (10) and method for testing a differential (4), the device comprising: a drive torque applicator (50) configured to be coupled to the differential and to apply a drive torque to the differential; a first restraining member (20a) adapted to couple with a first output shaft of the differential; and a second restraining member (20b) adapted to couple with a second output shaft of the differential; wherein the first and second restraining members (20a, 20b) are configured to prevent rotation of the first and second output shafts in the same direction in response to the drive torque and to force rotation of the first and second output shafts in opposite directions. The apparatus and method may be used to measure the threshold locking torque of an automatic locking differential by measuring the maximum torque difference as the torque difference exceeds the threshold locking torque and the differential enters the unlocked configuration. |
