Abstract
A vehicle includes an engine, a pair of front axle shafts, and a transfer case having a clutch assembly configured to selectively move between a closed position to enable the engine to drive the front axle shafts, and an open position to disable the engine from driving the front axle shafts. A control system is configured to momentarily open the clutch assembly when the vehicle is coming to a stop or is stopped in order to relieve residual torque build-up in the front axle shafts to thereby reduce idle vibration transmission between the engine and a body of the vehicle.
