GENERAL INFORMATION
STEERING SYSTEM COMPONENTS
Jeep vehicles can have either a manual or power
steering system (Fig. 1). A recirculating-ball type
steering gear is used for both systems.
Power steering systems use;
²Steering gear
²Pressure and return fluid hoses and fittings
²Belt driven steering pump
²Integral or remote body mounted pump reservoir
POWER STEERING GEAR
The steering gear is mounted on the left frame rail.
The gear is joined to the intermediate shaft by a uni-
versal joint coupling. The coupling helps isolate noise
and road shock from the interior.
The major internal components of the gear are the:
²Rotary valve assembly
²Steering worm shaft
²Rack piston assembly
²Pitman shaftThe movement of these parts, while turning or
parking, is aided by hydraulic pressure and flow sup-
plied by the pump. Manual steering is always avail-
able at times when the engine is not running or in
the event of pump or belt failure. Steering effort is
higher under such conditions.
The steering stub shaft, rotary valve, worm shaft,
and rack piston assembly are all in line. The oil pas-
sages are internal within the gear housing except for
pressure and return hoses between the gear and
pump.
The power steering gear has a recirculating ball
system. This acts as a rolling thread between the
worm shaft and rack piston. The worm shaft is sup-
ported by a thrust bearing at the lower end and a
bearing assembly at the upper end. When the worm
shaft is turned right, the rack piston moves up in
gear. Turning the worm shaft left moves the rack pis-
ton down in gear. The rack piston teeth mesh with
the sector, which is part of the pitman shaft. Turning
the worm shaft turns the pitman shaft, which turns
the wheels through the steering linkage.
The control valve in the steering gear directs the
power steering fluid to either side of the rack piston.
The rack piston is assisted by hydraulic pressure. If
the steering system loses hydraulic pressure, the ve-
hicle can be controlled manually, but with higher
steering effort.
An identification code located on the side cover des-
ignates the gear ratio (Fig. 2).
²Code BH designates 14:1 ratio used in XJ vehicles
²Code BF designates 13-16:1 ratio used in YJ vehi-
cles
A recirculating-ball steering gear is used with the
power (assisted) steering system (Fig. 1). The power
steering gear can be adjusted and internally serviced.

Replace the clutch discs if warped, worn, scored,
burned or charred, or if the facing is flaking off. Re-
place the steel plates if heavily scored, warped, or
broken. Be sure the driving lugs on the plates are in
good condition. The lugs must not be bent, cracked or
damaged in any way.
Replace the clutch spring and spring retainer if ei-
ther is distorted, warped or broken.
Check the lug grooves in the clutch retainer. The
steel plates should slide freely in the slots. Replace
the retainer if the grooves are worn or damaged.
Check action of the check ball in the retainer (Fig.
64). The ball must move freely and not stick.
Inspect the front clutch retainer bushings
carefully (Fig. 65). The retainer bushings are
not serviceable. It will be necessary to replace
the retainer if either bushing is scored, or
worn.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.FRONT CLUTCH ASSEMBLY
(1) Soak clutch discs in transmission fluid while
assembling other clutch parts.
(2) Install new seals on piston and in hub of re-
tainer. Be sure lip of each seal faces interior of clutch
retainer.
(3) Lubricate lips of piston and retainer seals with
liberal quantity of Mopar Door Ease, or Ru-Glyde.
Then lubricate retainer hub, bore and piston with
light coat of transmission fluid.
(4) Install clutch piston in retainer (Fig. 66). Use
twisting motion to seat piston in bottom of retainer. A
thin strip of plastic (about 0.0209thick), can be used
to guide seals into place if necessary.
CAUTION: Never push the clutch piston straight in.
This will fold the seals over causing leakage and
clutch slip. In addition, never use any type of metal
tool to help ease the piston seals into place. Metal
tools will cut, shave, or score the seals.
(5) Position spring in clutch piston (Fig. 67).
(6) Position spring retainer on top of piston spring
(Fig. 68).Make sure retainer is properly in-
stalled. Small raised tabs should be facing up-
ward. Semicircular lugs on underside of
retainer are for positioning retainer in spring.

Replace the retainer bushing if worn, scored, or
doubt exists about bushing condition.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.
Check condition of the fiber thrust washer and
metal output shaft thrust washer. Replace either
washer if worn or damaged.
Check condition of the seal rings on the input shaft
and clutch retainer hub. Replace the seal rings only
if worn, distorted, or damaged. The input shaft front
seal ring is teflon with chamfered ends. The rear ring
is metal with interlocking ends.
Check the input shaft for wear, or damage. Replace
the shaft if worn, scored or damaged in any way.
ASSEMBLING REAR CLUTCH
(1) Soak clutch discs in transmission fluid while
assembling other clutch parts.
(2) Install new seal rings on clutch retainer hub
and input shaft if necessary (Fig. 74).
(a) Be sure clutch hub seal ring is fully seated in
groove and is not twisted.
(b) Note that input shaft front seal ring is teflon
and rear seal ring is metal (Fig. 75). Be sure cham-
fered ends of teflon ring are properly joined and
that ends of rear ring are securely hooked together.
Lubricate both rings with transmission fluid after
installation.
(3) Lubricate splined end of input shaft and clutch
retainer with transmission fluid. Then press input
shaft into retainer (Fig. 76).
(4) Install input shaft snap ring (Figs. 70-71).
(5) Install new seals on clutch piston. Be sure lip
of each seal faces interior of clutch retainer.
(6) Lubricate lip of piston seals with generous
quantity of Mopar Door Ease, or Ru-Glyde. Then lu-
bricate retainer hub and bore with light coat of
transmission fluid.(7) Install clutch piston in retainer. Use twisting
motion to seat piston in bottom of retainer. A thin
strip of plastic (about 0.0209thick), can be used to
guide seals into place if necessary.
CAUTION: Never push the clutch piston straight in.
This will fold the seals over causing leakage and
clutch slip. In addition, never use any type of metal
tool to help ease the piston seals into place. Metal
tools will cut, shave, or score the seals.

CAUTION: The throttle valve, shuttle valve plug, 1-2
shift valve and 1-2 governor plug are made of
coated aluminum. Aluminum components can be
identified by the dark color of the special coating
applied to the surface (or by testing with a magnet).
DO NOT polish or sand aluminum valves or plugs
with any type of material, or under any circum-
stances. This practice might damage the special
coating and cause the valves and plugs to stick and
bind.
Inspect the valves and plugs for scratches, burrs,
nicks, or scores. Also inspect the coating on the alu-
minum valves and plugs (Fig. 119). If the coating is
damaged or worn through, the valve (or valve body)
should be replaced.
Aluminum valves and plugs should not be sanded
or polished under any circumstances. However, minor
burrs or scratches on steel valves and plugs can beremoved with crocus cloth but do not round off the
valve or plug edges. Squareness of these edges is vi-
tally important. These edges prevent foreign matter
from lodging between the valves, plugs and bore.
Inspect all the valve and plug bores in the valve
body. Use a penlight to view the bore interiors. Re-
place the valve body if any bores are distorted or
scored. Inspect all of the valve body springs. The
springs must be free of distortion, warpage or broken
coils.
Trial fit each valve and plug in its bore to check
freedom of operation. When clean and dry, the valves
and plugs should drop freely into the bores. Valve
body bores do not change dimensionally with use. If
the valve body functioned correctly when new, it will
continue to operate properly after cleaning and in-
spection. It should not be necessary to replace a
valve body assembly unless it is damaged in han-
dling.

GENERAL BODY SERVICE INFORMATION
RIGHT HAND DRIVE VEHICLES
The XJ Body Components procedures in this sec-
tion were developed on a left hand drive (LHD) vehi-
cle. Unless a component is unique to a right hand
drive vehicle, it will not be specifically covered in this
section, i.e. cargo barrier. In general, components on
left hand drive vehicles will be located on the oppo-
site side in right hand drive vehicles.
LABELS/DECALS/PLATESÐXJ
Most of the labels that are affixed to the vehicles
(Fig. 1 through 5) contain safety or maintenance in-
formation. If a body component or window glass are
replaced, a replacement label should be installed. In
most cases, label location on right hand drive (RHD)
vehicles will be on the opposite side of the vehicle.Refer to the Introduction of this manual for more
information involving labels and plates.
