2-WHEEL-DRIVE
FRONT
AXLE
The
front axle is of the reverse
Elliot
type. It is a
steel forging, heat treated for strength and ma­
chined
to
close
limits. The steering knuckles are
mounted on pins which pass through
openings
at each end of the
"I"
beam and are locked securely

in
position with tapered pins and nuts. The knuckles

ride
on
ball
thrust bearings for
ease
of steering. See
Figs.
M-12, M-13.

The
knuckles are connected by a tie rod which is
mounted on
ball
and socket connections. The tie

rod
is adjustable to secure correct
toe-in
of the front wheels. A steering connecting rod
connects

the
left
knuckle arm with the steering gear arm.

Standard
caster and camber of the front
wheels
are
built
into
the front axle. Wheel camber cannot
be changed however, caster can be adjusted by

placing
tapered shims or
wedges
between
the
springs and spring seats. For
complete
information

regarding
the steering
geometry

axle shaft and bearing assembly installed.

Note:
Make certain the bearing cup has been
removed from the axle housing.
f. Remove axle shaft oil seal from axle housing tube using tool C-637.
g. Wipe axle housing tube seal bore clean and in­

UNIT BEARING

Basically,
there are five parts to a Unit Bearing assembly: the cup, or outer race, the cup
ring,

the cone, or inner race, the tapered rollers which

roll
freely
between
the cup and cone, and the
cage

which
serves as a retainer to maintain the proper spacing
between
the tapered rollers grouped around
the cone.

When
the bearing is manufactured, the cup and
rib
ring are bonded
together
with an adhesive to
facilitate bearing handling and installation. Since the cup and rib ring are clamped
together
in the axle housing, there is no need for a permanent
bond. When the bearing is serviced the cup
will

usually
be separated from the rib
ring.

The
bearing is held on the shaft by the press fit of the
cone
plus the press fit of the retainer
ring.

The
cup and rib ring are clamped
together
in the axle housing through the outboard seal by the re­

tainer
plate. The outboard seal wipes on the rotat­ ing axle shaft and at the same time functions as a
static seal to prevent lubricant from escaping be­
tween the housing and the seal outside diameter.
It's
important to
note
that the seal serves also as

a
"spacer" or "filler" in the clamp-up of the bearing

in
the axle housing.

Note:
All Unit Bearings are manufactured with

built-in
adjustment for axle shaft end play. No adjustment shims are necessary when installing a
flange type axle shaft.

N-5.
Servicing Unit Bearing

The
Unit
Bearing
assembly should be serviced each
12,000
miles [
19,200
km.] with bearing cleaning,
inspection and relubrication. The Unit Bearing re­
quires
little attention while in service if the bear­
ings have been properly installed and are ade­
quately lubricated.
•
Cleaning and Inspection

a.
The Unit Bearing assembly should not be re­ moved from the axle shaft unless the outer seal is defective, the retainer plate is distorted or damaged,

or
the Unit Bearing is defective.

Should
it be necessary to remove the Unit Bearing

from
the axle shaft for any of
these
reasons, refer
to Par. N-7 for proper Unit Bearing removal.

b.
Clean
bearing cup with solvent and inspect cup
for any possible wear, nicks or damage.

c.
The bearing assembly can be cleaned in place
on the axle shaft. Use cleaning solvent and a stiff

bristle
brush to
loosen
the old grease. To assure
removal
of old grease and any contamination that
might be present, use compressed air. Air should be directed at the bearing assembly so that it
goes

through the bearing from one end of the rollers to the other. It is important not to "spin dry" the

bearing
with compressed
air.
Spinning the dry bear­ing may score the raceways and rollers due to
lack

of lubricant.

d.
Use cleaning solvent to clean out the bearing

and
oil seal bore in the housing. Wipe the area
clean
making sure it is free from old grease or other
contamination that might be present.

POWR-LOK
DIFFERENTIAL

As
optional equipment, Powr-Lok was previously available on all
Jeep
Universal
models
equipped
with
semi-float
tapered
axle
shafts.
The Powr-Lok

differential
may be identified by a tag located on
the opposite
side
of the differential housing
from
the ratio tag (Fig. N-2) and
stamped
with
either a "T" or
with
the words, "USE
LIMITED
SLIP
FIG.
N-37—YOKE INSTALLING TOOL
DIFF.
LUBE
ONLY."
This differential is available

for
rear
axles
only.
Whenever a
replacement
or conversion Powr-Lok
differential
is to be installed in an axle which has

been
previously in
service
and acquired mileage, be
sure
to record the amount of backlash
between

the ring
gear
and pinion at the time of
disassembly.

When the axle is again
assembled
the ring
gear
and pinion must be set to this
same
amount of
back­

lash.

Axle
ratios and
speedometer
gear
application is very important. In
like
model
axles,
the ratio may
be
changed
by simply changing to the desired ring
gear
and pinion;
except
in the
case
of the
3.73:1

or higher ratios. When changing
from
a
3.73:1
or higher to 3.54 or lower ratio, or vice
versa,
the
differential
case
must
also
be
changed
on a
stand­

ard differential
assembly,
and the differential as­ sembly,
less
ring
gear
and pinion, when a Powr-Lok

differential
assembly
is involved. When changing
from
any ratio to
another,
it
will
also
be
necessary

to
change
speedometer
gears.
Speedometer
gears

for
Powr-Lok and
standard
differentials of the
same
ratio, are
interchangeable.
A complete
rear

axle
assembly
replacement
is
necessary,
if a con­
version
from
one type of differential
assembly
to
another
is desired.
Note: Powr-Lok differentials use a special
lubri­

cant.
Refer to the Lubrication Chart.

N-21.
Trouble Symptoms and
Possible
Causes
If
noises
such
as
chatter
are
detected,
when turning
a corner, the probable
reason
for this is that incor­
rect
gear
lubricant has
been
installed in the axle.

Axles
equipped
with
a
limited
slip differential require special lubricant. Refer to Lubrication
Sec­

tion,
Par. B-52.
Note: It may be
necessary
to use an additive to
attempt to eliminate
chatter.
If this is not
success­
ful
then
disassembly
and inspection of the differen­

tial
becomes
necessary.

Warning:
Extreme
care
must be exercised on a
Powr-Lok
equipped vehicle to be
sure
the transmis­
sion is in the neutral position
whenever
the
engine

is
started
with
one wheel jacked up. Otherwise the
vehicle may lurch unexpectedly and
fall
off the
jack.

STEERING
SYSTEM

O-L
GENERAL

The
steering system on all Jeep Universal vehicles
consists of the steering gear, steering wheel, steering column and shaft, and steering linkage.
This

section covers wheel alignment, steering linkage,
steering gear, steering column and steering wheel.
0-2. Steering
Gear
Function

The
steering gear is a reducing gear. It exchanges a

relatively
large amount of movement with a small force (applied by the driver at the steering wheel), for a much smaller amount of movement with a
greatly increased force through a cam and lever
action type steering gear. The steering gear ratio is 17.9 to 1 on vehicles equipped with the F4
engine

and
19 to 1 with the V6 engine.
0-3. Steering
Linkage
Refer
to Fig. O-l.
The
steering linkage consists of a steering arm at­
tached to the steering gear, a steering connecting

rod,
(drag
link),
connecting the steering arm to the
beilcrank,
and a steering tie rod connecting the
beilcrank
to the axle tie rod. The beilcrank pivots
on a pin mounted just to the left of the frame front crossmember. The steering tie rod is connected to
the beilcrank and
extends
to the right
ball
joint as­ sembly of tie rod. The tie rod
extends
to the wheels,
being connected to their respective steering knuckle

arms
at the wheels.
With
this linkage arrangement,
as the steering arm
moves
rearward,
the front
wheels
turn
to the left. As the steering arm
moves
forward,
the wheels
turn
to the right.
Ball
joints are used to secure the drag
link,
steering
connecting rod and tie rod ends. The
ball
joints
assist in maintaining
good
steering control and con­
stant toe-in of the front wheels under all driving conditions. If the
ball
joints
become
worn enough
to allow free motion in the linkage, they should be,

replaced.

Note:
Ball
joint replacement of the tie rod requires
resetting of the wheel toe-in adjustment.
0-4.
Steering
Column
and Gear
Alignment
When
adjusting a steering gear remove all loads
from
the unit by disconnecting the steering con­
necting rod (drag
link)
from the steering arm and
also
loosen
the instrument panel bracket and the
steering gear to frame
bolts
to allow the steering

Disassembly
of
Steering
Gear
Refer
to Fig. 0-2.

When
the steering gear arm is installed on early
production vehicles, the line across the face of the

arm
and the end of the shaft should be in align­ ment. On later production vehicles, blind splines
on the lever shaft and in the steering gear arm en­

sure
correct positioning of the arm.

a.
Remove the steering gear arm with a puller
C-3646.

Caution:
Do not use a hammer or
wedge
to re­
move
the steering arm from the shaft and lever.

This
can cause damage to the shaft assembly.

b.
Loosen the lock nut and unscrew the adjusting

screw
two turns.

c.
Remove the side cover screws and washers. Re­
move
the side cover and gasket.

d.
Remove lever shaft.

e.
Remove upper cover plate screws. Remove cam,
wheel tube, and bearing assembly from the housing.
f.
Clean
all parts with suitable cleaning solvent and wipe dry.

g.
After dismantling as outlined above is com­
pleted, inspect cam
grooves
for wear, chipping and
scoring,
also the
ball
races on the cam ends and the
separate
ball
cups. Existence of any of
these
condi­ tions indicates the necessity for parts replacement.

h.
Inspect the tapered stud mounted on the lever
shaft for flat
spots
and chipping. In the case of
either, replacement is usually advisable. Inspect the
lever shaft for wear and
test
the fit of the shaft in
the bushings.

i.
Inspect condition of the oil seal at outer end of
lever shaft and the bearing at top end of steering
column.

0-25.
Reassembly
of
Steering
Gear
e Refer to Fig. 0-2.
Reassemble all parts to wheel tube in reverse order
of dismantling. Assemble cam, wheel tube and
bearing
assembly in housing, seating the lower

bearing
ball
cup in the housing.
Note:
New plastic retainer type cam bearings are
now available for the Ross steering gears. The new
bearings replace, and are interchangeable with,
the lock ring type cam bearings on gears equipped

with
early type cams.
With
adjusting shims in place, assemble upper
cover and adjust the cam bearings.
Assemble lever shaft in housing and with gasket
in
place assemble the side cover and set adjusting

screw
for a minimum backlash of the studs in the
cam
groove, with the steering gear at the center
point of travel.
When
assembling upper bearing spring and spring
seat in jacket tube make sure that the spring seat
is positioned correctly. It must be installed with
the lengthwise flange down against the bearing and
not up inside of spring coil.

Installation
of
Steering
Gear

a.
After the gear has been properly adjusted, as
outlined in Par. 0-5, install steering gear assembly
in
chassis in the reverse order in which it was re­
moved.

b.
After installing the assembly in the vehicle,

jack
up front of vehicle and place the front wheels
in
the straight ahead position.

c.
Temporarily install the steering wheel to locate
the mid-position of the steering gear. To locate the mid-position,
turn
the steering wheel as far to the

right
as possible and then
turn
in the
opposite
di­

rection
as far as possible, noting the total number
of turns.
Turn
the wheel back just ^ of the total movement to place the gear in mid-position.

d.
With
the steering gear in mid-position and the
wheels in the straight ahead position install steer­ ing gear arm on lever shaft with the
ball
end down.

When
installed the line across the face of the arm

and
end of shaft should be in alignment.

Refer to Fig. P-ll.

a.
Using Tool C-3785 or equivalent remove the
upper linkage rod and brake
shoe

b. Remove the brake
shoe
retainer, spring and pins.
c. Remove the anchor pin plate and tilt the brake

shoe
assembly out from the backing plate.

d.
On vehicles without a transmission brake,
spread the anchor
ends
of the primary and second­

ary
shoes
and remove the parking brake strut and
spring.

e. On vehicles without a transmission brake, dis­

engage
the parking brake cable from the parking
brake
lever and remove the brake assembly.
f. Overlap the anchor
ends
of the primary and
secondary
shoes
and remove the adjusting screw,
adjusting lever, lower return spring, and linkage
rods.
P-17. Inspection
Inspect the oil seals in the wheel hubs. If the con­
dition of any oil seal is doubtful, replace it. Install
the oil seal with an oil seal driver as shown in Fig.

P-9.

Brake
shoes
may be distorted by improper lining installation and linings should be ground true. For
this reason it is recommended that new or re­
placement
shoe
and lining assemblies be installed.
Using
brake drum micrometer C-3920 or equi­
valent, check all drums. Should a brake drum be rough and scored, it may be reconditioned by grinding or turning in a lathe. Do not remove more
than .030"
[0,762
mm.] thickness of metal .060" [1,52 mm.] overall diameter. If a drum is recon­
ditioned in this manner, either the correct factory-
supplied, oversize lining .030"
[0,762
mm.] must be
installed or a shim equal in thickness to the metal
removed must be placed
between
the lining and

shoe
so that the arc of the lining
will
be the same
as that of the drum.

If
it is found when
wheels
are removed that there
is brake fluid leakage at any of the wheel cylinders, it
will
be necessary to replace or recondition the
wheel cylinder (Par. P-21) and bleed the brake lines (Par. P-7).
Whenever the brake lining is replaced in one front
or one rear wheel, be sure to perform the same
operation in the
opposite
front or rear wheel, us­
ing the same brake lining part number. Otherwise, unequal brake action
will
result.
