Tool W-143, shown in Fig. K-12.

When
installing the end yokes on the output shafts,
inspect for the presence of
felt
seals in each oil
seal guard. (The oil seal guard is a part of each
yoke assembly.) Felt seals should be installed in the oil seal guards if
they
are not present. When
installing the shift
rail
oil seals in the front bear­

damage when passing over the shift
rail
notches.
Protect them with the thimble, and install them with the driver, Tool W-130, shown in Fig. K-9.

Each
shaft is equipped with a splined slip joint at one end to allow for variations in
length
caused by vehicle spring action.
Some
slip joints are marked
with arrows at the spline and

L-3.
When installing, align the arrows in the
same plane. If unmarked with arrows, align the
yokes
at the front and rear of the shaft in the same

parallel
plane. This is necessary to avoid vibration.

All
the universal joints used are similar in construc­
tion
except
that
some
are of the "U"-bolt
type

M-2. 4-WHEEL-DRIVE FRONT AXLE
The
front axle is a live driving unit with hypoid

type
driving gears and spherical steering knuckles mounted m pivot pins which ride on tapered roller bearings for
ease
of steering. The drive is of the
full
floating
type
through axle shafts built integrally

with
cardan cross universal joints which revolve in the steering knuckles. The steering knuckle tie rod

arm
is made integrally with the knuckle. The
knuckles
are connected by a divided tie rod to a steering bell
crank.
A steering connecting rod con­

nects
the bell
crank
to the steering gear arm. The

divided
tie rod is adjustable and the
toe-in
of each
front wheel is adjusted independently.

The
front wheel bearings should be checked every
12,000
miles. Refer to Section Q. Front wheel toe-

in
is adjustable by lengthening or shortening the
tie rod. However, standard caster and camber of
the front
wheels
are built
into
the axle. Wheel
caster can be adjusted by placing tapered shim
plates or
wedges
between
the springs and spring

seats
welded to the axle housing. Steering
geometry

and
front wheel adjustments are discussed in Sec­ tion O.

The
axle housing should be checked periodically
for weld cracks and/or other damage that may cause misalignment of the front
wheels
or
loss

of lubricant. The spring clips (U-bolts) should be
inspected and torqued every
12,000
miles. Torque (spring clip) nuts 45 to 50 lb-ft. [6,2 a 6,9 kg-m.].
