Abstract
A part time four wheel drive vehicle has an axle disconnect in its auxiliary drive axle. The axle disconnect comprises a vacuum motor and a tubular shift fork that drives a clutch sleeve so that the clutch sleeve translates between a first position where clutch teeth of the clutch sleeve engage clutch teeth of an outer axle shaft and a second position where the clutch teeth disengage. The vacuum motor and shift fork are housed in a modular assembly disposed between the axle and disconnect casing to improve packaging and reduce the size of the connect mechanism while providing better protection of the disconnect assembly from the outside environment.
