B
LUBRICATION
Note:
Hard
shifting of the transmission gear in
cold weather is a positive indication that the
lubri
cant
is of the wrong viscosity or of poor quality
which
allows it to congeal.
B-38.
Optional
4-Speed
Transmission
and
Transfer Case
The
four-speed transmission and transfer case re
quire
separate lubrication for each unit as
they
have no cross-over oil passage. At each transmission
service check, the
fill
plugs of
both
four-speed
transmission
and transfer case should be pulled
and
the lubricant refilled to level if necessary.
B-39.
Transfer
Case
Linkage
The
transfer case shift linkage should be lubricated
periodically.
All
bearing surfaces that are assembled
with
studs and cotter pins should be disassembled, cleaned, and coated with a
good
waterproof grease.
The
bearing surfaces that cannot be disassembled
should be lubricated with a lubricant that
will
penetrate the bearing
area.
These bearings include
the two on the cross shaft assembly and the
threaded stud.
The
type
of penetrating lubricant recommended is
DuPont
"PM 7", No. 2911, or its equivalent.
B-40.
Brake Master Cylinder
Clean
the top of the
fill
cap and also the housing
area
around it. Remove the cap and observe the
fluid
level. It should be
half
an inch
below
the top
of the fill-hole. If not, add brake fluid to
half
inch
[1,3 cm.]
below
the top of the fill-hole. Use
only heavy-duty brake fluid conforming to speci
fication
SAE-J-1703.
Be sure to handle the brake
fluid
in clean dispensers and containers that
will
not introduce even the
slightest
amount of other
liquids
or foreign particles. Replace and tighten
the
fill
cap.

Clutch Cross Shaft (Lever Type)
Lubricate
the clutch cross shaft in accordance with
specifications given in the
Lubrication
chart: see
Item
1. Chassis Bearings.
B-45.
Tie Rod and Drag
Link
Sockets
The
tie rod and drag
link
sockets
are equipped
with
lubrication
fittings
and should be lubricated
per
specifications given in the
Lubrication
chart: see Item 1. Chassis Bearings.
B-46.
Front
and
Rear Spring
Bushings
The
condition of the spring bushings is indicated
by the alignment of the spring pivot and spring
shackle
bolts.
Check
the alignment of
these
bolts,
and
check that nuts are
tightened
securely.
B-47.
Spring
Shackles
Rubber
bushings are provided on the spring
shackles.
These rubber bushings have no lubrication
fitting and it is very important that
they
never be lubricated.
B-48.
Shock Absorbers
Visually
check for broken mounts or bolts, worn
or
missing bushings on the shock absorbers. Refer
to Section S.
B-49.

B-52.
Conventional Differentials
To
remove the lubricant from the front or
rear
differential,
it is necessary to remove the housing cover. Let the lubricant
drain
out, and then flush
the differential with a flushing oil or light
engine
oil
to clean out the housing
(except
Powr-Lok
or
Trac-Lok
Differentials). Do not use water, steam,
kerosene, or
gasoline
for flushing.
Reinstall
the housing cover, replacing the gasket whenever necessary, torquing the cover
bolts
to 15 to 25 lb-ft. [2,1 a 3,4 kg-m.].
Remove the filler plug, and
refill
the differential
housing as specified in the
Lubrication
Specifica
tions.
B-53.
Powr-Lok
or
Trac-Lok Differential
Some vehicles may be equipped with the
Powr-Lok
or
Trac-Lok
Differential as optional equipment.
Special
lubricant and ordinary multipurpose gear
lubricants
must
not be used. Use only
'Jeep*
Differ
ential
Oil,
Part
No. 94557.
Powr-Lok
or
Trac-Lok
differentials may be cleaned
only by disassembling the unit and wiping with
clean
rags. Do not flush the unit. Refer to Sec
tion N.
B-54.
Front Axle Universal Joint
—
Lube
Check
the level of the front axle universal joint
lubricant
at each front wheel by removing the
fill-hole plug. The lubricant should be level with
the fill-hole. If required, add lubricant as specified
in
Lubrication
Specifications.
B-55.

Universal
Joint
— Service
On
all 4-wheel drive vehicles the front axle

joint should be serviced by removing the shaft and thoroughly cleaning the universal joints
and
housing. For the correct procedures, refer to
