DESCRIPTION AND OPERATION
FRONT WHEEL ASSEMBLY
Each front wheel and tire assem-
bly is bolted to its respective front
hub and brake drum assembly. Two
opposed, tapered roller bearings are
installed in each hub. A grease re-
tainer is installed at the inner end of
the hub to prevent lubricant from
leaking into the drum. The entire
assembly is retained to its spindle
by the adjusting nut, nut lock and
cotter pin (Fig. 1). The front wheel
assemblies rotate freely on their
respective spindles and are driven by
the motion of the car.
REAR WHEEL ASSEMBLY
The rear wheel hub and brake
drum assembly is retained to studs
on the rear axle shaft flange by three
speed nuts. The wheel and tire as-
sembly mounts on the same rear axle
shaft flange studs and is held against
the hub and drum by the wheel nuts.
The rear wheel bearing is pressed
onto the axle shaft just inside the
shaft flange, and the entire assembly
is retained to the rear axle housing
by the bearing retainer plate which
is bolted to the housing flange.
The inner end of each axle shaft
is splined to the engine powered
differential. The rear wheels are,
therefore, driven by the engine.

The front wheel bearings should
be adjusted if the wheel is loose on

specification.
1. Raise the car until the wheel
and tire clear the floor.
2. Pry off the wheel cover and
remove the grease cap (Fig. 1) from
the hub.
3. Wipe the excess grease from the
end of the spindle, and remove the
adjusting nut cotter pin and nut lock.
4. While rotating the wheel, hub,
and drum assembly, torque the ad-
justing nut to 15-20 ft-lbs to seat the
bearings (Fig. 2) .
5. Locate the nut lock on the ad-
justing nut so that the castellations
on the lock are aligned with the
cotter pin hole in the spindle.
6. Back off both the adjusting nut
and the nut lock together until the
