DESCRIPTION AND OPERATION
POWER STEERING GEAR
The power steering gear is mounted on the front
suspension crossmember (Fig. 1). The outer ends of
the outer tie rods attach to the steering knuckles.
The power steering gear operates as follows: Turn-
ing of the steering wheel is converted into linear
travel through the meshing of the helical pinion
teeth with the rack teeth of the gear. Power assist
steering is provided by a pump supplying fluid to
either side of the integral rack piston.Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. This movement
directs oil behind the integral rack piston, which, in
turn, builds up hydraulic pressure and assists in the
turning effort.
The drive tangs on the pinion of the power steering
gear mate loosely with a stub shaft. This is to permit
manual steering control to be maintained if the drive
belt on the power steering pump should break. How-
ever, under these conditions, steering effort will be
increased.

NOTE: The power steering gear should not be ser-
viced or adjusted. If a malfunction or oil leak occurs
with the steering gear, the complete steering gear
needs to be replaced.

AND CAUTIONS at the beginning of REMOVAL AND
INSTALLATION in this section.
REMOVAL
(1) Place the steering wheel in the STRAIGHT-
AHEAD position. Using a steering wheel holder, lock
the steering wheel in place to keep it from rotating
(Fig. 2). This keeps the clockspring in the proper ori-
entation.
(2) Inside the passenger compartment, remove the
steering column coupling retainer pin, back off the
pinch bolt nut, and remove the steering column cou-
pling pinch bolt (Fig. 3) (the pinch bolt nut is caged
to the coupling and is not removable). Separate the
upper and lower steering column couplings.
(3) Raise the vehicle. Refer to HOISTING in the
LUBRICATION AND MAINTENANCE group in this
service manual for the correct lifting procedure.(4) Remove both front tire and wheel assemblies
from the vehicle.
(5) Remove nuts attaching both outer tie rods to
the steering knuckles (Fig. 4). Remove each nut by
holding the tie rod stud stationary while loosening
and removing the nut with a wrench.
(6) Remove the outer tie rod from the steering
knuckles using Remover, Special Tool MB991113

(8) Release the locking tab on the wiring harness
connector for the power steering fluid pressure
switch before connector removal. Remove the wiring
harness connector from the power steering fluid pres-
sure switch (Fig. 6).
(9) Back out the tube nut securing the power
steering fluid pressure hose to the gear (Fig. 7).
(10) On vehicles without a power steering fluid
cooler, loosen the clamp, then disconnect the power
steering fluid return hose from the gear. If the vehi-
cle is equipped with a power steering fluid cooler, dis-
connect the cooler hose from the gear in place of the
power steering fluid return hose.
(11) If the vehicle is not equipped with a power
steering cooler, remove the power steering returnhose from the C-clamps on the outside of the two
routing clips on the front of the power steering gear.
(12) Open the routing clips on the front of the
power steering gear and remove the power steering
fluid pressure hose from the routing clips. At the
same time, if the vehicle is equipped with a power

(13) If the vehicle is equipped with a power steer-
ing fluid cooler, remove the two screws securing the
cooler to the front suspension crossmember. They are
located behind the cooler and can be accessed from
above. Allow the cooler to hang out of the way.
(14) Remove the bolt mounting the engine torque
strut to the right forward corner of the front suspen-
sion crossmember (Fig. 8).
NOTE: Before removing the front suspension
crossmember from the vehicle, the location of the
crossmember must be scribed on the body of the
vehicle (Fig. 9). Do this so that the crossmember
can be relocated upon reinstallation against the
body of vehicle in the same location as before
removal. If the front suspension crossmember is
not reinstalled in exactly the same location as
before removal, the preset front wheel alignment
settings (caster and camber) will be lost.
(15) Using an awl, scribe a line (Fig. 9) marking
the location of where the front suspension crossmem-
ber is mounted against the body of the vehicle.
(16) Position a transmission jack under the center
of the front suspension crossmember and raise it to
support the bottom of the crossmember.
(17) Loosen and completely remove the two front
bolts (one right and one left) attaching the front sus-
pension crossmember to the frame rails of vehicle.
The right side bolt can be viewed in the mounting
bolt figure (Fig. 8). The left side bolt is located in the
same location on the other side of the vehicle.(18) Loosen the two rear bolts (one right and one
left) attaching the front suspension crossmember and
lower control arms to the body of the vehicle until
they release from the threaded tapping plates in the
body of the vehicle. Do not completely remove the
rear bolts because they are designed to disengage
from the body threads yet stay within the lower con-
trol arm rear isolator bushing. This allows the lower
control arm to stay in place on the crossmember. The
right side bolt can be viewed in the mounting bolt
figure (Fig. 8). The left side bolt is located in the
same location on the other side of the vehicle.
(19) Lower the front suspension crossmember
using the transmission jack enough to allow the
power steering gear to be removed from the rear of
the crossmember (Fig. 10). When lowering front sus-
pension crossmember, do not let crossmember hang
from lower control arms. The weight should be sup-
ported by the transmission jack.
(20) Remove the roll pin securing the steering col-
umn lower coupling to the power steering gear pinion
shaft using a roll pin punch (Fig. 11). Push the steer-
ing column lower coupling up and off of the power
steering gear pinion shaft.
(21) Release the pinion shaft dash cover seal from
the tabs cast into the power steering gear housing
and remove the seal from the power steering gear
(Fig. 12).
(22) Loosen and remove the four bolts attaching
the power steering gear to the front suspension cross-
member (Fig. 1). Remove the power steering gear
from the front suspension crossmember.

INSTALLATION
(1) Install the steering gear on the front suspen-
sion crossmember (Fig. 1). Install the four power
steering gear mounting bolts. Tighten the mounting
bolts to a torque of 61 N´m (45 ft. lbs.).
(2) Install the pinion shaft dash cover seal over
the power steering pinion shaft and onto the power
steering gear housing. Align the holes on each side of
the seal with the tabs cast into the power steering
gear housing (Fig. 12).
(3) With the steering column lower coupling
pushed partway up through its hole in the dash
panel, match the flat on the inside of the steeringcolumn lower coupling to the flat on the power steer-
ing gear pinion shaft and slide the coupling onto the
top of the pinion shaft. Align the roll pin hole in the
coupling with the groove in the pinion shaft and
install the roll pin through the coupling until it is
centered (Fig. 11).
(4) Center the power steering gear rack in its
travel.
(5) Using the transmission jack, raise the front
suspension crossmember and power steering gear
until the crossmember contacts its mounting spot
against the body and frame rails of the vehicle. As
the crossmember is raised, carefully guide the steer-
ing column lower coupling up through its hole in the
dash panel.
(6) Start the two rear crossmember mounting bolts
into the tapping plates mounted in the body. The
right side bolt can be viewed in the mounting bolt
figure (Fig. 8). The left side bolt is located in the
same location on the other side of the vehicle. Next,
install the two front mounting bolts attaching front
suspension crossmember to frame rails of vehicle.
Lightly tighten all four mounting bolts to a approxi-
mately 2 N´m (20 in. lbs.) to hold the front suspen-
sion crossmember in position.
NOTE: When reinstalling the front suspension
crossmember back in the vehicle, it is very impor-
tant that the crossmember be attached to the body
in exactly the same spot as when it was removed.
Otherwise, the vehicle's wheel alignment settings
(caster and camber) will be lost.
