Inspection
To prevent possible injury or death
resulting from a vehicle falling from
a jack, follow the lifting procedure
in SAFETY section of this manual. Be sure the vehi-
cle is on a firm and level surface. Never get under a
vehicle while it is supported by a jack. Use jack
stands and test the stability of the vehicle on the
stands before starting any repair procedure. Always
place chocks in front and behind the wheels not
being raised. Use extreme care since the vehicle is
extremely unstable during the lifting process.
1. Lift the front of the vehicle and support on jack
stands as per the SAFETY section.
2. Rotate the front wheel and feel for any roughness.
3. While holding spindle with one hand, grasp bottom of
tire with other hand and rock tire back and forth on
spindle.
NOTICE: Some minor rocking movement of tire is
normal.
If excess movement is detected, the wheel bearing may
require repacking and adjusting or replacement. See the
Wheel Bearing Packing on page 48 See the Wheel Bear-
ing Adjustment on page 49
If the wheel bearing is satisfactory, a worn spindle bear-
ing, which is not a serviceable item, is indicated and the
spindle must be replaced. See the Spindle Replacement
on page 58

1.
Remove the hub from the spindle and disassemble.
See the Wheel Bearing and Race Replacement on
page 54 .
2. Clean all bearings, grease seal, hub and dust cap in
solvent and dry thoroughly. Inspect for signs of dam-
age. Pitting or a blue coloration of the rollers will
require replacement of the bearing. If the roller por-
tion of the bearing is to be replaced, the race must
also be replaced. See the Wheel Bearing and Race
Replacement on page 54 .
3. The front wheel bearings are the tapered roller type
and must be packed with grease at installation or any
time the bearing is removed for inspection. It is rec-
ommended that a bearing packer attached to a
grease gun be used; however, manual packing is
acceptable if done correctly. To pack a bearing man-
ually requires that a dab of grease be placed in the
palm of the hand and the bearing be dipped in the
grease. Force the grease up through and around all
