(6) Install the wormshaft bearing adjustment cap
in the housing and tighten it only enough to remove
the wormshaft end-play.
(7) Install the locknut on the wormshaft bearing
adjustment cap but do not tighten it at this time.
(8) Pack the steering gear housing with as much
chassis lubricant as possible.
Rotate the wormshaft in one direction until
the ball nut ceases. Pack the end of the housing
full of lubricant, rotate the shaft in the opposite
direction and repeat the packing procedure.
(9) Place the ball nut (Fig. 12) in the centered po-
sition, rotate the wormshaft from stop-to-stop and
count the number of rotations. Rotate wormshaft in
the reverse direction 1/2 of the number of rotations to
center the ball nut.
(10) Lubricate the pitman shaft with chassis lubri-
cant and insert it in the steering gear housing. En-
gage the center tooth on the shaft with the center
groove on the ball nut.
(11) Apply chassis lubricant to the replacement
housing cover gasket. Position it so that it surrounds
the housing cover opening.
(12) Place the shim(s) on the adjustment screw
and thread the screw into the cover to a depth of 2 to
3 threads.
(13) Slide the head of the adjustment screw into
the pitman shaft T-slot. With the cover in place, ro-
tate the screw counterclockwise to thread it into the
cover. Rotate the screw until the cover almost comes
in contact with the gasket.
(14) Install the cover retaining bolts finger tight
only. Continue tightening the adjustment screw coun-terclockwise until cover is tight against the gasket,
then loosen the screw 1/2 rotation.
(15) Tighten the cover bolts to 61 Nzm (45 ft. lbs.)
torque.
(16) Install the pitman shaft seal, refer to the re-
placement procedure.
(17) Rotate the wormshaft and observe the steer-
ing gear operation. With the adjustment screw and
cap loose, the wormshaft should rotate freely and not
bind. If the steering gear binds, repair as necessary.
(18) Inspect for lubricant leakage from the shaft
seals. If there is a leak at either seal, replace the de-
fective seal(s).
GEAR ADJUSTMENTS ON BENCH
WORM BEARING PRELOAD
(1) Tighten the worm bearing adjuster plug until it
bottoms, then loosen 1/4 turn.
(2) Carefully turn the wormshaft all the way to the
end of travel, then turn back 1/2 turn.
(3) Tighten adjuster plug until torque wrench indi-
cates 0.6 to 1.0 Nzm (5 to 8 in. lbs.) torque (Fig. 13).
(4) Tighten the adjuster plug locknut to 68 Nzm (50
ft. lbs.) torque.
OVER-CENTER PRELOAD
(1) Back off preload adjuster until it stops, then
turn it in one full turn.
(2) With gear at center of travel, check torque to
turn stub shaft. This will be reading #1 (Fig. 14).
(3) Turn adjuster in until torque to turn stub shaft
is 0.5 to 1 Nzm (4 to 10 in. lbs.) more than reading
#1.

AIRBAG MODULE REMOVEÐINSTALL
WARNING: THIS AIRBAG SYSTEM IS A SENSITIVE,
COMPLEX MECHANICAL UNIT. BEFORE ATTEMPT-
ING TO REMOVE OR INSTALL THE AIRBAG SYS-
TEM OR RELATED STEERING WHEEL AND
STEERING COLUMN COMPONENTS YOU MUST
FIRST DISARM THE AIRBAG FIRING MECHANISM.
FAILURE TO DO SO COULD RESULT IN ACCIDEN-
TAL DEPLOYMENT AND POSSIBLE PERSONAL IN-
JURY.
When removing a deployed airbag module,
rubber gloves, eye protection and long-sleeved
shirt should be worn. There may be deposits on
the airbag module and other interior surfaces,
which can cause irritation to the skin and eyes
in large doses.
(1) Disconnect battery negative cable and isolate.
(2) Using a small screwdriver, remove plastic cover
plug from top outer surface of steering wheel hub
(Fig 2). Exit vehicle and disarm airbag by reaching
through driver's side window and turning arming
screw counter-clockwise to its travel limit (Fig 3 and
4 ). This is done using an 8mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(3) From back side of steering wheel, remove 4
nuts attaching airbag module to steering wheel (Fig.
5). This is done using a 10mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(4) Remove airbag module from steering wheel.
(5) Reverse removal procedures to install. Tighten
airbag module attaching nuts to 9 to 11 Nzm (80 to
100 in. lbs.). Exit vehicle and arm airbag by reaching
through driver's side window and turning arming
screw clockwise to its travel limit. Arming screw
torque should not exceed 1.1 to 1.7 Nzm (10-15 in.
lbs.). Reinstall plastic cover plug in steering wheel
hub.
STEERING WHEEL
WARNING: BEFORE ATTEMPTING TO REMOVE OR
INSTALL THE AIRBAG SYSTEM OR RELATED
STEERING WHEEL AND STEERING COLUMN COM-
PONENTS YOU MUST FIRST DISARM THE AIRBAG
FIRING MECHANISM. WHEN SERVICING AIR BAG
SYSTEM, REMOVE AND ISOLATE THE BATTERY
NEGATIVE (-) CABLE (GROUND) FROM THE VEHI-
CLE BATTERY. YOU MUST DISARM THE AIRBAG
FIRING MECHANISM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT
AND POSSIBLE INJURY. WHEN AN UNDEPLOYED
AIR BAG ASSEMBLY IS TO BE REMOVED FROM
THE STEERING WHEEL, DISCONNECT THE BAT-
TERY GROUND CABLE AND ISOLATE. THE ARMING
SCREW MUST BE USED TO DISARM THE AIRBAG.

larger hole in the steering wheel. Pull the horn wire
through the smaller hole at the top.
(3) Install the retaining nut and tighten to 61 Nzm
(45 ft. lbs.) torque.Force the steering wheel down
on the shaft with the retaining nut only. Do not
hammer or shock the column with sudden im-
pact to install the wheel.
(4) Connect the wire feed to the horn buttons.
(5) Connect the wire feeds to the speed control
switch (Fig. 6). Tighten the air bag module nuts to 9
to 11 Nzm (80 to 100 in. lbs.) torque.

COLUMN COMPONENT SERVICE
The Acustar columns have been designed to be ser-
viced as an assembly; less wiring, switches, shrouds,
steering wheel, etc. Also most steering column com-
ponents can be serviced without removing the col-
umn from the vehicle. For additional information on
electrical components refer to Group 8, Electrical.
IGNITION SWITCH SERVICE
TEST AND REPAIR
If the ignition switch effort seems to be excessive
due to binding. Follow the procedure outlined below
to determine the cause.
When service procedures are performed on the
Acustar steering column there are certain areas of
the column that can not be tampered with. If a prob-
lem related to these areas of the steering column are
detected. The entire steering column (less the remov-
able components) should be replaced see (Fig. 1 and
2).
