The axle receives power from the transmission/

transfer case through the rear propeller shaft. The

rear propeller shaft is connected to the pinion gear

which rotates the differential through the gear mesh

with the ring gear bolted to the differential case. The

engine power is transmitted to the axle shafts

through the pinion mate and side gears. The side

gears are splined to the axle shafts.

The 9 1/4 Inch axle housings consist of a cast iron

center section with axle tubes extending from either

side. The tubes are pressed into and welded to the

differential housing to form a one-piece axle housing

The axles are equipped with semi-floating axle

shafts, meaning vehicle loads are supported by the

axle shaft and bearings. The axle shafts are retained

by C-locks in the differential side gears.
