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.

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.

MAY

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.

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 vehicle on the ground, disconnect the

steering column shaft coupler from the steering gear
intermediate coupler (Fig. 2).

(8) Remove a single 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.

(11) Remove bolts fastening leak detection pump to

cradle crossmember reinforcement. (Refer to 25 -

(12) Remove both outer tie rods from steering

knuckles, using Puller, Special Tool C-3894–A (Fig.
5).

(13) 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.

(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

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.
