Chapter 3 - Drive System: Drive Shafts and Differentials

89

DRIVE SYSTEM DESCRIPTION

1.

Chapter 2 of this manual covers the drive sys-
tem from the engine crankshaft to the output 
shafts of the transfer case. Chapter 3 covers the 
drive system down-stream of the transfer case.  
This includes:

•

The drive shafts from the transfer case to the dif-
ferentials

•

The front differential

•

The rear differential

•

The drive axles (half-shafts) that connect the dif-
ferentials to the wheel hubs.

2.

Drive shafts with Hooke-Spicer type universal 
joints extend fore and aft from the output shafts 
of the transfer case to drive the front and rear 
differentials. See Figure 3.1.

3.

Both drive shafts (front and rear) are driven 
whenever the transfer case is in gear, whether or 
not four-wheel drive is engaged.

Figure 3.1

Spicer-hooke type U-joint

4.

The 

rear differential

 has a cast iron housing 

and a cable-actuated locking feature.               
See Figure 3.2.

5.

The 

front differential

 has an aluminum hous-

ing, and an electrically controlled, slip sensing 
Auto-Lok® feature. See Figure 3.3.

5a.     The front differential is engaged or disen-

gaged using a rocker switch on the dash-
board.  An electric clutch connects the 
front differential pinion to the input shaft 
when energized.  When de-energized, the 
input shaft is still driven by the drive shaft, 
but the differential free-wheels.
