Differential Assembly: Description and Operation

REAR AXLE

DESCRIPTION
The 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 SRW axle has semi floating axle shafts, DRW has full floating axle shafts.

NOTE: Axle seals, axle bearings, pinion seal and differential cover are the only serviceable components. If differential is damaged/noisy the axle must be replaced.

OPERATION
The axle receives power from the transmission 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.
