DIFFERENTIAL
The differential carrier assembly may be removed,
while the axle is still installed in the truck, after the axle
shafts have been removed.
The drive pinion assembly and the differential case
assembly are mounted in the differential ca rrier, and are
removed as part of the carrie r when the ca rrie r is re ­
moved from the axle housing.
The differential is a conventional four pinion type with
ring gear bolted to flanged half of differential case. Dif­
ferential case is a two-piece type machined as a matched
assembly, and must be replaced as such.
Thrust washers are used between differential side
gears and case, and between differential pinions and case.

AXLE SHAFTS AND HOUSING
Axle shafts are full-floating type, splined to differential
side gears at inner ends and attached at flanged outer
ends to hubs by studs and nuts. Stud holes in each shaft
flange are taper-reamed to accommodate split tapered
dowels.
The banjo-type axle housing is one-piece design with
spring seats welded in place. Brake flange plates are
riveted to flanges welded on the axle housing tube. Outer
ends of housing are machined to accommodate wheel
bearings and threads are cut at extreme outer ends for
installation of wheel bearing nuts. The axle housing bowl
cover is welded to the axle housing.
