Abstract: A transfer case is provided utilizing dual planetary gearsets to provide a low gear ratio that can be engaged and disengaged on the fly without binding of gears. The transfer case provides an option for engaging the front, rear, both front and rear, or none of the wheels of a vehicle and is especially suited for off road vehicles such as rock crawlers.

Abstract: A process for converting a motor vehicle to a free towing motor vehicle. The process includes the steps of removing an axle between the differential and one of the driven wheels and replacing it with a pair of stub axles with a connect/disconnect lock therebetween. In order to tow the vehicle, the connect/disconnect lock is moved to the unlocked position so that the driven wheels may turn freely.

Abstract: In a four-wheel drive vehicle wherein the forward pair of wheels is driven through one differential assembly and the rearward pair of wheels through another differential assembly there is a transfer case through which power originating in the engine is distributed, or transfered, to the two differential assemblies. In the transfer case there is normally a third differential mechanism to compensate for differences in performance between the forward pair of wheels and rearward pair of wheels during on-the-road travel. The conversion kit of the invention makes use of a direct power transfer component in the transfer case at a location taking the place of the third differential mechanism, previously removed from the case.
