A transfer case for use with four-wheel drive vehicles incorporates a pass-through power takeoff shaft to drive remote secondary implements or accessory devices. The power takeoff shaft delivers rotational power from the vehicle transmission to the remote implement or accessory by passing through the housing of the transfer case to improve ground clearance and minimize driveline angles. The housing for the transfer case can mount bearings that rotatably support the power takeoff shaft. Alternatively, a tubular member can be mounted in the transfer case to provide a passageway through which the power takeoff shaft can pass through the transfer case. The points of engagement of the power takeoff shaft and the transfer case housing are sealed to prevent the loss of lubricating fluid from the transfer case. In each embodiment, the power takeoff shaft passes through the transfer case without engagement of or interference with the drive components therein.
