an oil base will discolor or injure white sidewall
tires.
5. Wheel Bearings
Tapered roller bearings are used in the front
wheels, Fig. 4-16, for greater durability. With
this design, the cone is integral with the roller
assembly.
a. Front Wheel Bearing Adjustment
When adjusting front wheel bearings, raise front
end of car and make sure that hub is completely
seated on spindle. Rotate wheel assembly and
tighten the adjusting nut to 30 foot-pounds, using
a 0-50 foot-pound torque wrench. Make certain
that all parts are properly seated and the threads
are free. Then back off nut one quarter turn (90°).
If cotter pin cannot be installed in either of the
two available holes in the spindle with nut in this
position, loosen adjusting nut until cotter pin can
be installed. The wheel should spin freely.
Bend one half of cotter pin toward end of shaft,
after cutting off end of pin short enough to prevent
its breaking radio static collector. Bend other
half of cotter pin over flat of nut. Cotter pin must
be tight after installation. If cotter pin can be
moved with finger, vibration may cause it to wear
and break, ending its protection.
b. Front Wheel Bearing Removal
1. Remove wheel disc.
2. Raise front end of car.
3. Remove wheel assembly from brake drum.
4. Remove dust cap, cotter pin, spindle nut,
washer, and outer cone and roller assembly,

cone and roller assembly.
NOTE: A simple tool, Fig. 4-17, may be
made out of cold rolled steel or from an old
screwdriver to facilitate removal of the grease
retainer. Use of this tool will prevent possible
damage to inner bearing assembly and hub sur-
face when removing retainer.
7. Inner and outer bearing cups are a press
fit in hub, and can be removed by driving out
from opposite side with a long punch.
NOTE: Discolored stripes on bearing races
of new cars do not necessarily indicate a rough
bearing race.

thoroughly, replacing the complete assembly if
any parts are worn, pitted, or rough.
