DESCRIPTION AND OPERATION
STEERING GEAR OPERATION DESCRIPTION
NOTE: The power steering gear (Fig. 1) should NOT
be serviced or adjusted. If a malfunction or oil leak
occurs, the complete steering gear should be
replaced.
If a steering gear boot needs to be replaced due to
damage, refer to the power steering gear service sec-
tion in this manual for proper procedure.
The power steering system consists of these four
major components. Power Steering Gear, Power
Steering Pump, Pressure Hose, and Return Line.Turning of the steering wheel is converted into linear
travel through the meshing of the helical pinion
teeth with the rack teeth. Power assist steering is
provided by an open center, rotary type control valve
which directs oil from the pump to either side of the
integral rack piston.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As required
steering effort increases, as in a turn, the torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This move-
ment directs oil behind the integral rack piston,
which, in turn, builds up hydraulic pressure and
assists in the turning effort.

CAUTION: Proper torque on the cradle plate to
suspension cradle mounting bolts is very impor-
tant.
(8) Install cradle plate on front suspension cradle
and install the 10 cradle plate to cradle attaching
bolts and nuts (Fig. 8). Tighten all attaching bolts to
a torque of 165 N´m (123 ft. lbs.).
(9) Install the bracket (Fig. 9) attaching the power
steering fluid tubes to the front suspension cradle.
CAUTION:
(10) Install the power steering fluid return hose on
the steel tube at the front suspension cradle (Fig. 4).
(11) Install a screw type hose clamp on the power
steering hose to steel tube connection.Be sure hose
clamp is installed on return tube past the upset
bead on the tube.Tighten the screw clamp to a
torque of 2 N´m (18 in. lbs.).
CAUTION: The protective heat shield sleeves must
cover the entire rubber hose and hose to tube con-
nection portion of both the power steering fluid
pressure and return hoses (Fig. 4). This is required
to prevent the power steering hoses from being
overheated.
(12) When used, properly position the protective
heat sleeves on the power steering hoses. Then, tie
strap the heat sleeves to the power steering hoses to
keep them in their proper position.
(13) Install the front tire and wheel assemblies on
vehicle. Install the wheel lug nuts and torque to 129
N´m (95 ft. lbs.).
(14) Lower the vehicle to a level were the interior
of vehicle is accessible.
(15) Using the intermediate coupler, turn the front
wheels of the vehicle to the left until the intermedi-
ate coupler shaft is properly aligned with the steer-
ing column coupler. Assemble the steering column
shaft coupler (Fig. 3) onto the steering gear interme-
diate coupler. Install steering column coupler to
intermediate shaft retaining pinch bolt (Fig. 3).
Tighten the pinch bolt nut to a torque of 28 N´m (250
in. lbs.).
CAUTION: Do not use automatic transmission fluid
in the power steering system. Only use Mopar,
Power Steering Fluid or an exact equivalent prod-
uct.
(16) Fill power steering pump fluid reservoir to the
proper level.
(17) Start the engine and let run for a few seconds.
Then turn the engine off.(18) Add fluid if necessary. Repeat the above pro-
cedure until the fluid level remains constant after
running the engine.
(19) Raise front wheels of vehicle off the ground.
(20) Start the engine. Slowly turn the steering
wheel right and left, lightly contacting the wheel
stops. Then turn the engine off.
(21) Add power steering fluid if necessary.
(22) Lower the vehicle and turn the steering wheel
slowly from lock to lock.
(23) Stop the engine. Check the fluid level and
refill as required.
(24) If the fluid is extremely foamy, allow the vehi-
cle to stand a few minutes and repeat the above pro-
cedure.
(25) Fill power steering reservoir to correct level
with Mopart, Power Steering Fluid, or equivalent.
(26) Adjust toe (Refer to Group 2 Suspension).

STEERING COLUMN DESCRIPTION
The steering column (Fig. 1) has been designed to
be serviced only as a complete assembly, if a compo-
nent of the steering column is defective. The only
replaceable components of the steering columnassembly are the key cylinder, ignition switch, multi-
function switch, clockspring, halo lamp, speed control
switches, driver airbag, trim shrouds and steering
wheel. These replaceable components of the steering
column can be serviced without requiring removal of
the steering column from the vehicle.

CAUTION: Before installing the steering wheel the
clockspring must be centered. If clockspring is not
centered, the wiring in the clockspring may be over-
extended and break when the steering wheel is
rotated. Use the following procedure to center the
clockspring.
CLOCKSPRING CENTERING PROCEDURE
²Depress the 2 plastic locking pins to disengage
the lock mechanism (Fig. 25).
²With the lock mechanism disengaged, rotate the
clockspring rotor clockwise until the rotor stops.Do
not apply excessive force.
²From the end of the clockwise travel, rotate the
rotor three turns counterclockwise. The clockspring
wires should be at the top. Engage clockspring lock-
ing pins.
²From the center locked position, rotate the clock-
spring one-half additional turn counterclockwise. The
clockspring wiring should now be at the bottom. The
clockspring is now correctly positioned for installa-
tion of the steering wheel.
CAUTION: Do not force steering wheel onto steer-
ing column shaft by driving it on. Pull steering
wheel down onto shaft using ONLY the steering
wheel retaining nut.
(18) Align master splines on steering wheel and
steering shaft, and flats on steering wheel with for-
mations on clock spring. Install the steering wheel on
the steering column shaft (Fig. 26). All wiring leads
from the clock springmustbe routed as shown in
(Fig. 26).
NOTE: Before installing the damper on the steering
wheel, inspect the damper to ensure the rubber iso-
lator on the damper is not deteriorated or damaged.If the damper is installed with a damaged isolator a
buzz, squeak or rattle condition may develop.
(19) Install the steering wheel damper on the
steering wheel. When damper is installed, itmustbe
positioned on the steering wheel as shown in (Fig. 7).
(20) Install the steering wheel to steering shaft
retaining nut. Tighten the steering wheel retaining
nut to a torque of 61 N´m (45 ft. lbs.).
(21) Install the wiring leads from the clock spring
on the air bag, horn switch wire, and speed control
switches (Fig. 6). Attach the wire routing clip (Fig. 6)
to the studs on the air bag module.
(22) Install the air bag module in the steering
wheel.
