Rear Axle - 8 1/4
DESCRIPTIONThe 8 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.
The axles have a vent hose to relieve internal pressure caused by lubricant vaporization and internal expansion.
OPERATION
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.
