NOTE: ** To evaluate this condition, it may be nec-
essary to disconnect the coupling at the base of the
steering column. Turn the steering wheel and feel or
listen for internal rubbing in steering column. To
avoid damaging the column clockspring, note the
following. Before disconnecting coupling, place
tires in the straight-ahead position and center steer-
ing wheel. Once disconnected, DO NOT rotatesteering wheel more than one revolution in either
direction and place steering wheel in original loca-
tion before reconnecting coupling. If this position is
lost, the steering column clockspring must be
recentered following the procedure found within the
procedure for steering column installation in the
steering column section.

ing gear. This travel pushes and pulls the tie rods to
change the direction of the vehicle's front wheels.
Power assist steering provided by the power steer-
ing pump is controlled by an open center, rotary type
control valve which directs oil from the pump to
either side of the integral rack piston upon demand.
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.
Manual steering control of the vehicle can be main-
tained if power steering assist is lost. However,
under this condition, steering effort is significantly
increased.
SERVICE WARNINGS AND CAUTIONS
WARNING: POWER STEERING FLUID, ENGINE
PARTS AND EXHAUST SYSTEM MAY BE
EXTREMELY HOT IF ENGINE HAS BEEN RUNNING.
DO NOT START ENGINE WITH ANY LOOSE OR DIS-
CONNECTED HOSES. DO NOT ALLOW HOSES TO
TOUCH HOT EXHAUST MANIFOLD OR CATALYST.
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH THE ENGINE OFF TO PREVENT PERSONAL
INJURY FROM MOVING PARTS.
CAUTION: When the system is open, cap all open
ends of the hoses, power steering pump fittings or
power steering gear ports to prevent entry of for-
eign material into the components.
REMOVAL - GEAR
CAUTION: Positioning the steering column in the
locked position will prevent the clockspring from
being accidentally over-extended when the steering
column is disconnected from the intermediate
steering coupler.
(1) Remove cap from power steering fluid reser-
voir.
(2) Using a siphon pump, remove as much fluid as
possible from the power steering fluid reservoir.
(3) With the ignition key in the locked position
turn the steering wheel to the left until the steering
wheel is in the locked position.
(4) With the vehicle on the ground, disconnect the
steering column shaft coupler from the steering gear
intermediate coupler (Fig. 2).(5) Raise vehicle on jack stands or centered on a
frame contact type hoist. See Hoisting in the Lubri-
cation and Maintenance section of this service man-
ual, for the required lifting procedure to be used for
this vehicle.
(6) Remove front wheel and tire assemblies.
(7) Remove hoses at power steering cooler and
allow fluid to drain.
(8) On both sides of vehicle, remove nut attaching
outer tie rod end to steering knuckle (Fig. 3).
Remove nut by holding tie rod end stud with a
socket while loosening and removing nut with
wrench.
(9) Remove both tie rod ends from steering knuck-
les, using Puller, Special Tool C-3894±A (Fig. 4).
(10) Remove the lower control arm rear bushing
retainer bolts located on each side of each lower con-
trol arm rear bushing.
NOTE: The bolts fastening the cradle crossmember
reinforcement are of two different thread sizes. Note
the location of the various sizes.
(11) Remove the bolts attaching the cradle cross-
member reinforcement to the front suspension cradle
crossmember (Fig. 5). Remove the 2 bolts fastening
the reinforcement and rear of cradle crossmember to
the body of the vehicle. Remove the reinforcement.
(12) If the vehicle is equipped with All-Wheel-
Drive, remove the power transfer unit (Refer to 21 -
TRANSMISSION/TRANSAXLE/POWER TRANSFER
UNIT - REMOVAL).

retainer bolts through reinforcement on each side of
each lower control arm rear bushing. Tighten bolts to
a torque of 61 N´m (45 ft. lbs.).

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 onto the steering gear intermediate
coupler (Fig. 2). Install steering column coupler to
intermediate shaft retaining pinch bolt. Tighten the
pinch bolt nut to a torque of 28 N´m (250 in. lbs.).
(16) Perform the POWER STEERING PUMP INI-
TIAL OPERATION procedure to properly fill and
bleed the power steering system. (Refer to 19 -

PUMP
DESCRIPTION
Hydraulic pressure for the operation of the power
steering gear is provided by a belt driven power
steering pump. The power steering pump is mounted
on the back side of the engine on all engine applica-
tions. The pumps are different depending on the
engine option. The pump for the 2.4L engine is made
out of cast iron and steel. The pump used on the
3.3L/3.8L engine is made of aluminum.
The pump for the 3.3L/3.8L engine does not have a
return fitting as the pump for the 2.4L engine does.
The power steering return hose on the 3.3L/3.8L
engine goes to the reservoir instead of the pump.
OPERATION
The power steering pump is a constant flow rate
and displacement vane type pump. The power steer-
ing pump used on all applications is the Vane-Sub-
merged remote reservoir style power steering pump.
The remote reservoir type pump has the pump
housing and internal components combined with the
fluid housing. It has a remote reservoir for the power
steering fluid supply.Fig. 1 POWER STEERING PUMP (2.4L)

STANDARD PROCEDURE - POWER STEERING
PUMP INITIAL OPERATION
CAUTION: The fluid level should be checked with
engine off to prevent injury from moving compo-
nents. Use only MoparTPower Steering Fluid (MS-
5931) or approved equivalent. Do not overfill.
Read the fluid level through the side of the power
steering fluid reservoir. The fluid level should indi-
cateªFILL RANGEºwhen the fluid is at a temper-
ature of approximately 21ÉC to 27ÉC (70ÉF to 80ÉF).
(1) Wipe the filler cap and area clean, then remove
the cap.
(2) Fill the fluid reservoir to the proper level and
let the fluid settle for at least two (2) minutes.

then turn the engine off.
(4) Add fluid if necessary. Repeat the above steps
until the fluid level remains constant after running
the engine.
