A gear drive assembly includes an elongated housing with a cavity and a pair of opposed apertures in communication with the cavity. At least one output shaft extends through the apertures. A drive gear is positioned in the cavity and fixedly connected to the at least one output shaft for rotation therewith. The drive gear and the output shaft have a predefined range of travel in a direction of the longitudinal axis to facilitate assembly of the gear drive assembly. A spacer is located within the cavity between the housing and the drive gear and is configured to preclude movement of the drive gear and the output shaft through the predefined range of travel after assembly. A drive motor can be mounted on the housing for transferring power to the at least one output shaft. A bearing and seal assembly is mounted in the housing around the drive shaft of the drive motor and an axial spacer is located between the drive motor and the bearing and seal assembly to thereby prevent movement of the bearing and seal assembly. A variable length mount can be located at a longitudinal end of the housing. The mount may be shortened to accommodate various mounting criteria of a vehicle.
