8. When inspecting or replacing bearings, make
sure the bearing cone (inner race) is free to creep
on spindle of steering knuckle. The cones are de­
signed to creep on the spindle In order to afford a
constantly changing load contact between the cones
and the roller bearings. Polishing the spindle or
applying bearing lubricant will permit creeping and
prevent rust forming between cone and spindle.
9. Be sure bearing parts have been thoroughly
cleaned and air-dried because bearing lubricant
will not adhere to wet or oily surfaces.
10. Use a bearing packer if available and thor­
oughly pack both bearing assemblies with new high
melting point wheel-bearing lubricant. Remove any
excess lubricant.
11. Apply a light coat of lubricant to spindle and
inside surface of wheel hub.
12. Place inner bearing in race of wheel hub and
install a new grease seal.
13. Clean loose material from brake drum with
compressed air. Be sure inner hub and bearings
are covered. Inspect lining contact area for oil and
grease. Clean with a non-flammable non-toxic sol­
vent (such as denatured alcohol). Make sure wiping
cloth and fluid do not become loaded with grease
from repeated use.
14. Inspect brake linings for oil and grease con­
tamination. Clean by wiping with a non-flammable,
non-toxic solvent (such as denatured alcohol). Sand
lightly to rough up surface of linings.
