Removal
Index mark the driveshaft (4602) in relation to the transfer case and front axle universal joint flange. Disconnect the double Cardan joint from the flange at the transfer case and the single U-joint from the flange at the front axle. Remove the driveshaft. Wrap tape around the bearing caps (front) to prevent the bearings from falling off the U-joint spiders.
Installation
Align index marks and position the single U-joint end of the driveshaft to the front axle and install the U-bolts and nuts.
Position the double Cardan joint to the transfer case with index marks aligned and install the four bolts and lockwashers.
Tighten the bolts at the transfer case to 27-38 Nm (20-28 lb-ft), and the U-bolts and nuts at the front axle to 11-20 Nm (8-15 lb-ft).
