DESCRIPTION
A rack and pinion steering gears (Fig. 1) is made
up of two main components, the pinon shaft and the
rack. The gear cannot be adjusted or internally ser-
viced. If a malfunction or a fluid leak occurs, the gear
must be replaced as an assembly.
REMOVAL
NOTE: The steering column on vehicles with an
automatic transmission may not be equipped with
an internal locking shaft that allows the ignition key
cylinder to be locked with the key. Alternative meth-
ods of locking the steering wheel for service will
have to be used.
(1) Lock the steering wheel.(2) Drain and siphon the power steering fluid from
the reservoir.
(3) Raise the vehicle.
(4) Remove and discard the steering coupler pinch
bolt.
(5) Remove the power steering hoses from the rack
& pinion.
(6) Remove the tire and wheel assembly.
(7) Remove the tie rod end nuts and separate tie
rod ends from the knuckles with Special tool 8677
(Refer to 19 - STEERING/LINKAGE/TIE ROD END -
REMOVAL).
(8) Remove the skid plate (Refer to 13 - FRAME &
BUMPERS/FRAME/FRONT SKID PLATE -
REMOVAL).
(9) Remove the rack & pinion mounting bolts. (Fig.
2) & (Fig. 3)
(10) Remove the rack & pinion from the vehicle.

DESCRIPTION
The power steering gear is a recirculating ball type
gear (Fig. 1). The gear ratio's used are 12.5:1.
OPERATION
The gear acts as a rolling thread between the
worm shaft and rack piston. The worm shaft is sup-
ported by a thrust bearing at the lower end and a
bearing assembly at the upper end. When the worm
shaft is turned from input from the steering column
the rack piston moves. The rack piston teeth mesh
with the pitman shaft. Turning the worm shaft, turns
the pitman shaft, which turns the steering linkage.
REMOVAL
(1) Place the front wheels in a straight-ahead posi-
tion.
NOTE: The steering column on vehicles with an
automatic transmission may not be equipped with
an internal locking shaft that allows the ignition key
cylinder to be locked with the key. Alternative meth-
ods of locking the steering wheel for service will
have to be used.
(2) Lock the steering wheel.
(3) Siphon out as much power steering fluid as
possible.

(4) Disconnect and cap the fluid hoses from steer-
ing gear (Refer to 19 - STEERING/PUMP/HOSES -
REMOVAL).
(5) Remove coupler pinch bolt at the steering gear
and slide shaft off gear (Fig. 2).
(6) Mark the pitman shaft and pitman arm for
installation reference. Remove the pitman arm from
the shaft with Puller C-4150A (Refer to 19 - STEER-
ING/LINKAGE/PITMAN ARM - REMOVAL), (Fig. 3).
(7) Remove steering gear three mounting bolts
(Fig. 4). Remove the steering gear from the vehicle.
INSTALLATION
(1) Position the steering gear on the frame rail and
install the three mounting bolts (Fig. 4). Tighten the
mounting bolts to 196 N´m (145 ft. lbs.).(2) Align steering coupler on gear shaft. Install
pinch bolt and tighten to 49 N´m (36 ft. lbs.) torque.
(3) Align and install the pitman arm (Refer to 19 -
STEERING/LINKAGE/PITMAN ARM - INSTALLA-
TION).
(4) Install the washer and retaining nut on the pit-
man shaft. Tighten the nut to 305 N´m (225 ft. lbs.).
(5) Connect fluid hoses to steering gear (Refer to
19 - STEERING/PUMP/HOSES - INSTALLATION),
tighten to 31 N´m (23 ft. lbs.).
(6) Add fluid, (Refer to 19 - STEERING/PUMP -
STANDARD PROCEDURE).
(7) Reset the toe and center the steering wheel
(Refer to 2 - SUSPENSION/WHEEL ALIGNMENT -
STANDARD PROCEDURE).
ADJUSTMENTS
ADJUSTMENT
CAUTION: Steering gear must be adjusted in the
proper order. If adjustments are not performed in
order, gear damage and improper steering response
may result.
NOTE: Adjusting the steering gear in the vehicle is
not recommended. Remove gear from the vehicle
and drain the fluid. Then mount gear in a vise to
perform adjustments.
(1) Remove the steering gear from the vehicle
(Refer to 19 - STEERING/GEAR - REMOVAL).
(2) Mount the gear carefully into a soft-jawed vise.

CAUTION: Do not overtighten the vise on the gear
case. This may affect the adjustment
(3) Hold the steering gear upside down over a
drain pan and rotate the input shaft back and forth
several times lock-to-lock to discharge the fluid from
the steering gear
(4) Rotate the input shaft to the left stop and then
back-off approximately 45 degrees. Using an inch-
pound torque wrench on the input shaft, record the
peak torque required to slowly and evenly rotate the
input shaft clockwise
1¤2turn (180 degrees) starting
from the 45 degree position. This peak torque read-
ing is the preload torque. The preload torque must be
within2-10in-lbs.
(5) Rotate the input shaft to its center of travel
(approximately 1.5 turns from either stop). Place the
torque wrench on the input shaft with the handle in
the vertical position. Rotate the torque wrench slowly
and evenly
1¤4turn (90 degrees) each side of center
and record the peak torque measure on or near cen-ter. This total on-center torque reading must be5-9
in-lbs higher than the previously measured preload
torque without exceeding a total of 17 in-lbs. The
value of the total on-center minus the preload torque
is defined as the meshload torque
(6) If required, adjust the on-center torque by loos-
ening the adjuster screw lock nut and turning the
adjuster screw until the total on-center and meshload
torque readings fall within the specified values. Turn
the adjuster screw clockwise to increase and counter-
clockwise to decrease the torque reading. While hold-
ing the adjuster screw in place, tighten the lock nut
to 31 N´m (23 ft. lbs.).
(7) Re-check the preload and on-center torque
readings.
(8) Install pitman arm on the steering gear (Refer
to 19 - STEERING/LINKAGE/PITMAN ARM -
INSTALLATION).
(9) Reinstall steering gear to the vehicle (Refer to
19 - STEERING/GEAR - INSTALLATION).
