lubricant should be added until a
lubricant
rise is
observed.

ing attaching bolt and the filler plug.
STEERING GEAR FLUID CHECKING PROCEDURE (POWER).
Run the engine until
the
fluid
is
at
normal operating temperature {165
degrees F to 175 degrees
F).
Then
turn the steering wheel all the
way to
the left and right several
times, and
shut
off
the engine.
Check the fluid level in the power
steering reservoir.
The level
must show
on
the cross
hatching between
the
bottom of the
Dipstick
and the full
mark (Fig.
1).
If the level
is low, add
automatic transmission
fluid
M2C33F.
Do not overfill the reservoir.

CLEANING AND INSPECTION
mERINO GEAR CUANING
AND INSPECnON
Wash all parts in a cleaning sol-
vent and dry with a lint-free cloth.
Tile bearlq lhould aot be spun dry
wltb eomprelled *·Inspect the shaft
and worm for scoring, cracks or
checks, and for straightness .of the
abaft. Check the splines and the
threads on the sector shaft for wear
and
burn.
Inspect the gear teeth for
scoring, pitting and other wear. In-
spect the ball bearings for free move-
ment, and the cups for wear or irreg-
ular surfaces. Check the housing for
cracks and the sector shaft needle
bearing ·for free movement or other
wear.
Check
the
power steering pump
pressures. If the pump pressures are
not to specification and there are no
external fluid leaks, replace the
pump.
If the pump has a visible leak, replace
the reservoir
seal,
outlet valve seals,
or support stud seal, whichever is re·
quired.
fLUSHING THE POWER

when
in-
stalling a new pump.
1. Remove
the
power
steering
pump
and pulley as
outlined
in page
3-26.
2. Install a new pump and connect
only the
pressure hose to the pump
(page 3-26).
3. Place the oil return line in a
suitable container and plug the re-
servoir
return pipe.
4.
Fill the
reservoir
with
fluid
M2C33-F.
S. Disconnect the coil wire to pre-
vent the
engine
from starting and
raise the front wheels off the ground
6.
While approximately two quarts
of steering gear fluid are being
poured into the reservoir, tum the
engine
over using the ignition key,
at the same time cycle the steering
wheel from stop to stop.
7. As soon as all of the fluid has
been poured in, tum off the ignition
key, and attach the coil wire.
I. Remove the plug from the res-
ervoir return pipe, and attach the re-
turn hose to the reservoir.
9. Check the reservoir fluid level;
if low add fluid to the proper level.
Do not overftll.
10. Lower the car.
11. Start the engine and cycle the
steering wheel from stop to stop to
expel any trapped air from the sys-
tem.
FRONT END GENERAL
INSPECTION
Check for damage that would af-
fect the runout of the wheels. Wob-
ble or shimmy caused by a damaged
wheel will cause premature tyre wear
and eventually damage the wheel
bearings. Inspect the wheel rims for
dents that could permit air to leak
from the tyrea
WHEEL BALANCING
See the instructions provided with
the
.
Wheel Balancer.
SHOCK ABSORBERS
Passenger cars and station wagons
are equipped with hydraulic shock ab-
sorbers of the direct-acting type and
are nonadjustable and nonrefillable,
and cannot be repaired.
Before replacing a shock absorber,
check the action of the shock ab-
sorbers by grasping the bumper and
jouncing the car up and down. If the
shock absorbers are in good condi·
tion
the car will immediately settle to
a normal position after the bumper is
released.
TESTING
To check a shock absorber
re-
moved from a car proceed as fol·
lows:
1.
Hold the shock absorber in the
vertical position w i t h the piston
in the same position, push in the pis-
ton rod until the shock is extended to
its full length.
2. With the shock absorber held
in the same position, push in the pis·
ton rod until the .shock is compressed
to its shortest length.
3, Repeat steps 1 and 2 several
times until all the air is expelled.
4. Clamp the lower end (small di·
ameter) in a vise in a vertical posi·
tion.
S. Extend the shock to its full
length and then compress it to its
shortest length. There should be a
constant drag during the complete
cycle. Any sudden loss of drag indi·
cates air in the system, loss of fluid,
or faulty internal valve operation.
Replace defective shock absorbers.
UPPER BALL JOINT INSPECTION
1.
Raise the car on a frame con-
tact hoist or by ftoor jacjcs placed
beneath the underbody until the
wheel falls
to
the full down posi-
tion as shown in
Fig. 13. This will
unload the upper
ball joint.
l. Adjust the wheel bearings al>
described in
3. Attach a dial indicator to the
upper arm.
4. With
the
dial indicator at-
tached to the
upper arm,
position
the indicator so that the plunger
rests against the
inner side
of the
wheel rim adjacent to the upper
arm ball
joint.
5. Grasp the tyre at the top and
bottom,
and slowly move the tyre
in and out (Fig.
13).
Note the read-
ing (radial
play) on
the dial indica-
tor.
If
the
reading
exceeds
specifi·
~.:ations
{l'art 3-1), replace the
upper
ball
j~int.
