Drive/Propeller Shaft: Description and Operation
Front
The front driveshaft connects the power flow from the transfer case to the front drive axle. It incorporates a double Cardan universal joint, a splined stub
shaft end, a universal joint slip yoke boot with two clamps (one large and one small), and a driveshaft slip yoke that attaches to the transfer case.
CAUTION: Under no circumstances is the driveshaft to be clamped in the jaws of a vise or similar holding fixture. Denting or localized fracture of the
tube can result, which could cause driveshaft failure during vehicle operation.
NOTE: Whenever the vehicle is raised on a hoist, inspect the universal joint slip yoke boot for rips or tears. Replace if required.
