2. Steering column shaft rubbing. 2. Move or realign item rubbing shaft.
3. Clockspring noisy. 3. Remove clockspring. Reinstall wheel.
If noise is gone, replace clockspring.
4. Seal lubrication inadequate. 4. Lube seal (if external).
5. Steering gear internally noisy. 5. Replace steering gear (if no other
cause can be found).
SCRUBBING OR
KNOCKING NOISE.1. Incorrect tire or wheel size. 1. Replace incorrect size tire or wheel
with size used as original equipment.
2. Interference between steering
gear and other vehicle components.2. Check for bent or misaligned
components and correct as necessary.
3. Steering gear internal stops worn
excessively allowing tires to be
steered excessively far.3. Replace steering gear.
* NOTE: There is some noise in all power steering
systems. One of the most common is a hissing
sound evident when turning the steering wheel
when at a standstill or when parking and the steer-
ing wheel is at the end of its travel. Hiss is a very
high frequency noise similar to that experienced
while slowly closing a water tap. The noise is
present in every valve and results when high veloc-
ity fluid passes valve orifice edges. There is no
relationship between this noise and the perfor-
mance of the steering system.** NOTE: A light clunk may be felt or heard during
steering wheel reversal while vehicle is stationary.
This results from internal steering gear rack move-
ment at the bushings and in no way affects the per-
formance of the steering system. This movement
may be felt in the steering components during
steering wheel reversal.
*** NOTE: Power steering pump growl/moan/groan
results from the development of high pressure fluid
flow. Normally this noise level should not be high
enough to be objectionable.

GEAR
DESCRIPTION
This vehicle is equipped with a rack and pinion
power steering gear (Fig. 1). It is mounted to the
underside of the front suspension cradle/crossmem-
ber.
The steering column is attached to the gear
through the use of an intermediate shaft and cou-
plers. The outer ends of the power steering gear's
outer tie rods connect to the steering knuckles.
NOTE: The power steering gear should NOT be ser-
viced or adjusted unless DaimlerChrysler Corpora-
tion authorizes. If a malfunction or oil leak occurs,
the complete steering gear should be replaced.
Only the outer tie rods may be replaced separately
from the rest of the gear.
OPERATION
Turning of the steering wheel is converted into lin-
ear (side-to-side) travel through the meshing of the
helical pinion teeth with the rack teeth in the steer-
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 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.
WARNING
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
REMOVAL - LHD GEAR
(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.Use
care not to damage the filter mesh below the
fluid surface.
19 - 26 GEARRS

(14) Remove the bolts attaching the cradle cross-
member reinforcement to the front suspension cradle
crossmember (Fig. 6). Remove the 2 bolts fastening
the reinforcement and rear of cradle crossmember to
the body of the vehicle. Remove lower rear bushings,
then the reinforcement.
(15) If the vehicle is equipped with All-Wheel-
Drive, remove the power transfer unit as necessary
(Refer to 21 - TRANSMISSION/TRANSAXLE/
POWER TRANSFER UNIT).
(16) Remove tube nuts and power steering pres-
sure and return hoses from the power steering gear
(Fig. 7).
(17) Remove the 3 bolts and nuts mounting the
steering gear to the front suspension cradle (Fig. 8).NOTE: The next step must be done to allow the
removal of the steering gear from the front suspen-
sion cradle. The steering gear can not be removed
from the vehicle with the intermediate coupler
attached to the steering gear.
(18) Lower steering gear from suspension cradle
enough to allow access to the intermediate coupler
roll pin (Fig. 9). Install Remover/Installer Special
Tool 6831A through the center of the roll pin, secur-
ing with the knurled nut (Fig. 9). Hold threaded rod
stationary while turning nut, this will pull the roll
pin out of the intermediate coupler.
(19) Separate the coupler from the shaft of the
steering gear.
(20) Remove the power steering gear from the
vehicle.
REMOVAL - RHD GEAR
(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.
CAUTION: Locking the steering column in the
straight-ahead position will prevent the clockspring
from being accidentally over-extended when the
steering column is disconnected from the interme-
diate steering coupler.
(3) Position the steering wheel in the STRAIGHT-
AHEAD position. Lock the steering wheel in place
using a steering wheel holding tool.
(4) With the ignition key in the locked position
turn the steering wheel to the left until the steering
wheel is in the locked position.
(5) With the vehicle on the ground, disconnect the
steering column shaft coupler from the steering gear
intermediate coupler (Fig. 2).
(6) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(7) Remove front wheel and tire assemblies.
(8) If power steering cooler equipped, remove a
hose at power steering cooler and allow fluid to
drain.
(9) Remove 2 bolts attaching power steering cooler
to cradle crossmember reinforcement (Fig. 3).
(10) On both sides of vehicle, remove nut attaching
outer tie rod end to steering knuckle (Fig. 4).
Remove nut by holding tie rod end stud with a
socket while loosening and removing nut with
wrench.

PUMP
DESCRIPTION
DESCRIPTION - PUMP (2.4L/3.3L/3.8L
ENGINE)
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 madeout of cast iron and steel (Fig. 1). The pump used on
the 3.3L/3.8L engine is made of aluminum (Fig. 2).
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.
19 - 36 PUMPRS

DESCRIPTION - PUMP (DIESEL)
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
front lower right corner of the engine (Fig. 13).
The pump has a supply fitting for fluid coming
from the reservoir and a pressure port for exiting
fluid that is headed for the steering gear.
OPERATION
The power steering pump is a constant displace-
ment vane type pump. The 2.4L pump has an inte-
gral fluid reservoir and there is a secondary remote
non-flow reservoir which acts only as a fluid fill and
check point. The 3.3L/3.8L pump houses very little
fluid and is therefore supplied by a remote flow
through reservoir.
