1. Front Wheel Bearings. Wipe old grease
out of hub and wash bearings. Work approx-
imately one tablespoon of wheel bearing lubri-
cant into each ball bearing. The oil seal pack-
ings should be examined for wear or leaking
and replaced if necessary.
Bearing Adjustment. Take up spindle nut
with 10" wrench until bearings are preloaded
at least 1 hex, then rotate wheel 1
revoluti on
to make sure bearings are seated. Back
off
spindle nut until bearings are loose.
Tighten
nut until all bearing looseness is just removed,
then line up nut to nearest cotter hole and in-
stall cotter pin. Do not mistake loose king pin
bushings, etc., for wheel bearing looseness.
CAUTION: Bearing preload must not exceed
1/12 turn of nut.
Inspect Brake Linings and Drums while
front wheels are off. If linings are thin or
drums are beginning to score, the car owner
should be notified.
2. Shock Absorbers. Thoroughly clean off
all dirt from top of shock absorbers, front and
rear, to avoid getting dirt into absorbers when
filler plugs are removed.
(a) Front Shock Absorbers. Remove filler
plugs and add fluid until it overflows, using
only G.M. or Delco Shock Absorber
Fluid.
In-
stall plugs loosely to exclude dirt and bounce
front of car up and down by front bumper to
force out any air in cylinders. Repeat addition
of fluid and bouncing of car until no more fluid
can be added, then install filler plugs securely.
(b) Rear Shock Absorbers. Remove filler
plugs and add G.M. or Delco Shock Absorber
Fluid until level is
23/32"
to
V2"
below filler
openings. Install plugs loosely to exclude dirt
and bounce car up and down by rear bumper
to force out any air in cylinders. Add additional
fluid, if necessary, and adjust fluid level to
23/32"
to
V2"
below filler openings, then install
filler plugs securely. Correct level in rear ab-
sorbers may be conveniently obtained by use
of Shock Absorber Gun K.M.O. 1026 and
Adapter J 1611. The gun is used to fill absorber
and the adapter is placed on gun nozzle to suck
out surplus fluid.
(c) Air Space. Shock absorbers require
some air space for expansion of fluid when hot,
otherwise fluid may be forced out. Air space is
built into front absorbers, but must be pro-
vided in rea?" absorbers by leaving fluid level at
specified distance below filler opening.
