FRONT
AXLE
INSTALLATION

To
install the front axle, reverse the procedures described in
Par.
M-4 and then perform the follow­
ing operations:

a.
Torque spring clip plate (U-bolt) nuts securing the axle to the front springs, (see Par. M-4).

b.
Adjust and bleed the brakes (see Section P).

c.
Check
axle lubricant level and
fill
as necessary, (see Section B).

d.
Check
front end wheel alignment (see Section
O).
e.
Check
wheel turning angle. Refer to Par. M-14.

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
refer to the
Section O.

M-16.
Removal of Solid
Front
Axle

Note:
The procedure for removing the solid front
axle varies slightly, depending on whether the
springs are slung under or over the axle. These

variations
are
noted
in the following procedure.

a. -
Raise the front end of the vehicle and safely support the frame behind the springs.

b.
Remove the
wheels
by removing the wheel
discs and lug nuts.

c.
Disconnect the steering connecting rod at the
ball
and socket connection on the steering knuckle. 282

GENERAL

Semielliptical
leaf springs are used for all models.
The
springs are hung longitudinally from the frame
side rails by means of brackets welded to the
rails.
All
axles are firmly attached to the springs by U-

bolts
(spring clips), spring saddles welded to the
underside of the axles, and spring plates under the
springs.
Early
model DJ-5 and DJ-6 front axles (I beam) are attached to the springs with conven­
tional
bolts
and spring plates. Spring center
bolts
are
inserted in the axle spring saddles to prevent
shifting of the axle.

All
front springs, except as noted below, are pro­vided with shackles at the front ends of the springs

and
pivot
bolts
at the
rear
ends of the springs. Model CJ-5 up to
Serial
No. 44437 and Model

CJ-6
up to
Serial
No. 11981 are provided with shackles at the
rear
ends of the front springs, and
pivot
bolts
at the front ends.

Note:
Models
CJ-5A
and
CJ-6A
are equipped with
the two
stage
type front and
rear
spring.

All
rear
springs are provided with shackles at the

rear
end and pivot
bolts
at the front end.
Springs
should be examined periodically for broken

or
shifted leaves,
loose
or missing rebound clips,
angle of spring shackles, and position of springs
on the saddles. Springs with shifted leaves do not have their normal strength. Missing rebound clips may permit the spring leaves to fan out or break
on rebound. Broken leaves may make the vehicle

hard
to handle or permit the axle to shift out of

line.
Weakened springs may break causing difficulty
in
steering. Spring attaching clips or
bolts
must be tight. It is
suggested
that they be checked at each
vehicle inspection and torqued 45 to 55 lb-ft. [6,2 a 7,6 kg-m.].

S-2.
Spring Shackles

Rubber-bushed
shackles are provided on all current
production vehicles. The steel-backed rubber (silent bloc) bushings are pressed into the spring

eyes
and mounting brackets. The shackle
bolts
tighten the side plates against the inner steel back­
ing of the bushings. Oscillation of the springs is
taken in the rubber bushings.

All
vehicles produced before early 1957 were
equipped with U-shackles and threaded core bush-
