ABSTRACT:
The present invention includes novel apparatus and methods for engaging and disengaging a locking differential. In an embodiment, an assembly for use with a locking differential is provided. The assembly includes an actuator, a housing, a shaft, a pair of biasing members, a side gear, and a locking pin. The actuator is arranged to move the assembly from a first position to a second position. The housing is coupled to the actuator. The first biasing member biases the housing, and the second biasing member biases the housing and shaft. The side gear includes an aperture for engaging the locking pin. The locking pin is coupled to the shaft such that the biasing of the shaft determines whether the locking pin is biased into engagement with the aperture or out of engagement with the aperture.
