B-l. GENERAL
All
'Jeep' Universal vehicles require periodic
lubri­

cation and other maintenance services for normal
vehicle
usage
and application to promote satis­ factory operation and prevent
excessive
wear. Un­
der severe operating or atmospheric conditions
these
services should be performed more
often
than
under normal conditions. It should also be remem­
bered that common short trips and
stop-and-go
driving
are more severe on lubrication

Engine Oil

For
maximum
engine
protection under all driving conditions encountered during the recommended

oil
change intervals, it is necessary to use only

"MS"
certified
sequence-tested
oils. The term
"MS"
must appear on the oil container singly or

in
conjunction with other designations. "MS" des­
ignated oils are heavy-duty detergent oils that are
formulated to withstand all service conditions in
modern powerplants. Engine oils designated only
as
"ML"
and/or
"MM"
are not recommended and should not be used except in an emergency when

"MS"
oil is not available. Certified
sequence-tested

engine
oils are described on their containers by

such
phrases as:
meets,
exceeds,
excels, or has
proven superior in the
test
requirements,
test
sequences, MS Service
tests,
standards, and service

requirements,
of automotive manufacturers, auto­
makers,
or car manufacturers for MS service or
Service
MS.
It
may be necessary to change
engine
oil more
frequently than normally recommended, depending upon the type and quality of oil used, the severity
of operation conditions, if the
engine
is used for
short
periods in cold weather, or if the
engine
is allowed to idle for excessive periods.

Always
drain
the crankcase while the
engine
is hot since
dirt
and contaminants are then more
likely
to be held in suspension and therefore
will

drain
out more completely.
Drain
the crankcase as follows:

a.
Position the
drain
receptacle under the
drain

plug.

b.
Remove the
drain
plug using the correct size

wrench.
Be careful of hot oil.
c.
Carefully
clean the
drain
plug. Inspect and

replace
the gasket, if deteriorated.
d.
When the oil has drained, replace and tighten
the crankcase
drain
plug. 12

Reinstall
the axle shafts, and

the housings to

specified in
Lubrication
Specifications.

B-56.
Front
Axle Wheel Bearings

To
lubricate the wheel bearings, it is necessary
to remove, clean, repack, and adjust them. When
front wheel hubs and bearings are removed for
lubrication,
they should be thoroughly washed in a
suitable cleaning solvent. The bearings should be
carefully
dried and then given a thorough cleaning

and
inspection. Use a clean brush to remove all

particles
of old lubricant from bearings and hubs.

After
the bearings are cleaned, inspect them for
pitted races and rollers. Also, check the hub oil
seals.

Note:
Wheel bearing lithium base lubricants are
used at the factory for
initial
fill
of
these
bearings.
When
lithium base and sodium base lubricants are

mixed,
the result is a thinned-out mixture that
can
bleed through seals. It is therefore important
that lubricants with the correct base be used when

lubricating
the wheel bearings.
Should
leaks occur at wheel bearing seals, the leaks

may
be caused by a mixture of two
types
of
lubri­

cants.
In such cases, the old lubricant should be
completely removed before new lubricant is added.

Wheel
bearings should be thoroughly cleaned,
lubricated
with lithium base and reinstalled.

Repack
the bearing
cones
and rollers with grease

and
reassemble hub in the reverse order of the
disassembly. Test the bearing adjustment as out­

lined
in Section Q.

B-57.
Rear
Axle Wheel Bearings

The
Rear
wheel bearings an early models equipped

with
lubrication fittings with a vent opening
through the housings above each fitting should be
lubricated
sparingly, each
2,000
miles
[3.200
km.].

Use
a hand compressor and wheel bearing grease,
forcing
the grease through each lubrication fitting

until
it flows from the vent. Vent should be kept
clear
of obstruction or grease
will
back up into the

brakes.
Do not add grease after it flows from the
vent for it may be forced through the wheel key-
way
onto
the outside of the wheel and possibly

onto
the brake linings.
Rear
wheel bearings that do
not have lubrication fittings should be removed
each
12,000
miles
[19.200
km.] and the bearing
cleaned, inspected and repacked. Refer to proce­

dure
in Par. B-56.

Note:
When servicing the Flanged Axle Unit
Bear­

ing Assembly, refer to Section N, Par. N-5 for

proper
lubrication procedures.

B-58.
Propeller Shafts
and
Universal Joints

The
propeller shaft slip joints and universals should
be lubricated with a hand compressor grease gun so as to not damage the bearing seals. The units
should be lubricated with a
good
quality grease.

Refer
to the
Lubrication
Chart
for lubrication fre­
quency and lubricant type and grade. B-59.
Lights
and
Controls

a.
Check
all interior and exterior lights and light
switches for proper operation, including: parking
lights, headlamps (high beam and low beam),

tail
lights, brake lights, directional lights, and in­ strument panel lights.

b.
Check
all instrument panel controls and
instru­

ments for proper operation.

B-60.
Speedometer Cable

Remove the
speedometer
cable from its housing every
12,000
miles
[19.300
km.].
Clean
it thor­
oughly and coat it with a
good
quality light graphite grease.

B-61.
Headlights

Refer
to Section H.

B-62.
Heater Controls

Apply
Lubriplate
130-A to all friction points and
pivot points on the heater controls panel unit as well as the pivot points at the dashpot. Apply

a
few drops of penetrating oil all along the Bowden
cable.
This
oil
will
penetrate into the center wire.

B-63.
Windshield Wiper and
Washer Controls

Lubricate
the friction points and the pivot points
on the windshield wiper transmission and linkage

arms
with a slight amount of
Lubriplate

Centrifugal Governor

Check
the oil level in the governor housing at each
vehicle lubrication. Use the same seasonal grade
oil
as is used in the

the housing above
the level indicating plug opening. Keep the vent

in
the filler plug open at all times. 17

License Plate
Light

On
CJ-5A,
CJ-6A
and current production vehicles
the license plate light is attached to the tailgate
and
is of the swing-type design to enable the
license plate to be visible when the tailgate is in
the down psoition. The bulb can be changed by
removing
the clear plastic lens. On early production
vehicles the license plate light is integral with the

tail
light assembly.

Horn
The
horn is mounted under the hood on the
left

front
fender. The horn is sounded by pressing the
button located at the top center of the steering
wheel.

To
remove the horn wire, disconnect the wire at
the snap connection at the base of the steering
column.
Pull
off the rubber horn button cap and
the brass contact cap from the steering wheel nut.

This
will
expose
the contact tip of the horn wire.

Pull
the wire out of the steering column from the top. Refer to Fig. H-62.

The most frequent causes of

loose
connec­
tions and burned-out bulbs. A flashing rate

approximately
twice the normal rate usually in­
dicates a burned-out bulb in the
circuit.
