DESCRIPTION
The tilt and standard column (Fig. 1) has been
designed to be serviced as an assembly; less wiring,
switches, shrouds, steering wheel, etc. Most steering
column components can be serviced without remov-
ing the steering column from the vehicle.
OPERATION
SERVICE PRECAUTIONS
Safety goggles should be worn at all times when
working on steering columns.
To service the steering wheel, switches or the air-
bag, refer to the WARNINGS and CAUTIONS below.
WARNING: THE AIRBAG SYSTEM IS A SENSITIVE,
COMPLEX ELECTRO-MECHANICAL UNIT. BEFORE
ATTEMPTING TO DIAGNOSE, REMOVE OR INSTALL
THE AIRBAG SYSTEM COMPONENTS YOU MUST
FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO
MINUTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE. FAILURE TO DO SO COULD RESULT IN
ACCIDENTAL DEPLOYMENT OF THE AIRBAG AND
POSSIBLE PERSONAL INJURY. THE FASTENERS,
SCREWS, AND BOLTS, ORIGINALLY USED FOR
THE AIRBAG COMPONENTS, HAVE SPECIAL COAT-INGS AND ARE SPECIFICALLY DESIGNED FOR THE
AIRBAG SYSTEM. THEY MUST NEVER BE
REPLACED WITH ANY SUBSTITUTES. ANYTIME A
NEW FASTENER IS NEEDED, REPLACE WITH THE
CORRECT FASTENERS PROVIDED IN THE SERVICE
PACKAGE OR FASTENERS LISTED IN THE PARTS
BOOKS.
CAUTION: Do not hammer on steering column shaft
or shift tube. This may cause the shaft/shift tube to
collapse or damage the bearing.
CAUTION: Do not attempt to remove the pivot pins
to disassemble the tilting mechanism. Do not
remove shaft lock plate, plate retainer, park lock
link or slider. This will damage the column (Fig. 2)
and (Fig. 3).
REMOVAL
(1) Position the front wheels straight ahead.
(2) Disconnect the negative (ground) cable from
the battery.
(3) Remove the airbag, (Refer to 8 - ELECTRICAL/
RESTRAINTS/DRIVER AIRBAG - REMOVAL).
(4) Remove the steering wheel with an appropriate
puller,(Refer to 19 - STEERING/COLUMN/STEER-
ING WHEEL - REMOVAL).

UMN/STEERING WHEEL - INSTALLATION).
(16) Install the airbag, (Refer to 8 - ELECTRICAL/
RESTRAINTS/DRIVER AIRBAG - INSTALLATION).
(17) Column shift vehicles, connect the shift link
rod to the transmission shift lever. Use multi-purpose
lubricant, or an equivalent product, to aid the instal-
lation.
(18) Install the battery ground (negative) cable.

KEY-IN IGNITION SWITCH
DESCRIPTION
The key-in ignition switch is integral to the igni-
tion switch, which is mounted on the left side of the
steering column. It closes a path to ground for the
Central Timer Module (CTM) when the ignition key
is inserted in the ignition lock cylinder and the
driver door ajar switch is closed (driver door is open).
The key-in ignition switch opens the ground path
when the key is removed from the ignition lock cyl-
inder. The ground path is also opened when the
driver door ajar switch is open (driver door is closed).The key-in ignition switch cannot be repaired and,
if faulty or damaged, the entire ignition switch must
be replaced, (Refer to 19 - STEERING/COLUMN/IG-
NITION SWITCH - REMOVAL).
DIAGNOSIS AND TESTING - IGNITION SWITCH
AND KEY LOCK CYLINDER
ELECTRICAL DIAGNOSIS
For ignition switch electrical schematics, refer to
Ignition Switch in the appropriate section of Electri-
cal Wiring Diagrams.

GEAR
DESCRIPTION
The power steering gear is a recirculating ball type
gear (Fig. 1). The gear ratio's used are 17.5:1 and
14:1.
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 abearing 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.

GEAR LEAKAGE
(1) Possible power steering gear leakage areas.
(Fig. 2).

REMOVAL
(1) Place the front wheels in a straight-ahead posi-
tion.
(2) Disconnect and cap the fluid hoses from steer-
ing gear.
(3) Remove coupler pinch bolt at the steering gear
and slide shaft off gear (Fig. 3).
(4) Mark the pitman shaft and pitman arm for
installation reference. Remove the pitman arm from
the shaft with Puller C-4150A (Fig. 4).(5) Remove steering gear retaining bolts and nuts.
Remove the steering gear from the vehicle.INSTALLATION
(1) Position the steering gear on the frame rail and
install the bolts. Tighten mounting bolts to specifica-
tions.
(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.
(4) Install the washer and retaining nut on the pit-
man shaft. Tighten the nut to 251 N´m (185 ft. lbs.).
(5) Connect fluid hoses to steering gear, tighten to
31 N´m (23 ft. lbs.). Add fluid, (Refer to 19 - STEER-
ING/PUMP - STANDARD PROCEDURE).
ADJUSTMENTS
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.

WORM THRUST BEARING PRELOAD
(1) Mount the gear carefully into a vise.
CAUTION: Do not overtighten the vise on the gear
case. This may affect the adjustment
(2) Remove adjuster plug locknut (Fig. 5).
(3) Rotate the stub shaft back and forth with a 12
point socket to drain the remaining fluid.
(4) Turn the adjuster in with Spanner Wrench
C-4381. Tighten the plug and thrust bearing in the
housing until firmly bottomed in the housing about
28-31 N´m (20-23 ft. lbs.).
(5) Place an index mark on the housing even with
one of the holes in adjuster plug (Fig. 6).
(6) Measure back (counterclockwise) 18 mm (0.70
in) and mark the housing (Fig. 7).
(7) Rotate adjustment cap back (counterclockwise)
with spanner wrench until hole is aligned with the
second mark (Fig. 8).
(8) Install and tighten lock nut to 108 N´m (80 ft.
lbs.). Be sure adjustment cap does not turn while
tightening the lock nut.
PITMAN SHAFT OVER-CENTER PRELOAD
NOTE: Before performing this procedure, the worm
bearing preload adjustment must be performed.
(1) Rotate the stub shaft with a 12 point socket
from stop to stop and count the number of turns.
(2) Starting at either stop, turn the stub shaft
back 1/2 the total number of turns. This is the center
of the gear travel (Fig. 9).(3) Place the torque wrench in the vertical position
on the stub shaft. Rotate the wrench 45 degrees each
side of the center and record the highest rotational
torque in this range (Fig. 10). This is the Over-Cen-
ter Rotating Torque.
NOTE: The stub shaft must rotate smoothly without
sticking or binding.

(4) Rotate the stud shaft between 180É and 270É to
the left of center and record the left off-center pre-
load. Repeat this to the right of center and record the
right off-center preload. The average of these two
recorded readings is the Preload Rotating Torque.
(5) The Over-Center Rotating Torque should be
0.23-0.68 N´m (2-6 in. lbs.)higherthan the Preload
Rotating Torque.
(6) If an adjustment to the Over-Center Rotating
Torque is necessary, first loosen the adjuster lock
nut. Then turn the pitman shaft adjuster screw back
(COUNTERCLOCKWISE) until fully extended, then
turn back in (CLOCKWISE) one full turn.
(7) Remeasure Over-Center Rotating Torque. If
necessary turn the adjuster screw and repeat mea-
surement until correct Over-Center Rotating Torque
is reached.
NOTE: To increase the Over-Center Rotating Torque
turn the screw CLOCKWISE.
(8) Prevent the adjuster screw from turning while
tightening adjuster lock nut. Tighten the adjuster
lock nut to 49 N´m (36 ft. lbs.).
