STEERING 19 - 3i STEERING COLUMN
SERVICE INFORMATION The Acustar columns
(Fig.l)
have been designed to
be serviced as an assembly; less wiring, switches, shrouds, steering wheel, etc. Also most steering col­
umn components can be serviced without removing
the column from the vehicle. For additional informa­
tion refer to Group 8H, Electrical.

CAUTION:
Bumping,
jolting
and
hammering
on the

steering
column
shaft
and
gear shift
tube
must
be

avoided during
all
service procedures.

CAUTION:
Disconnect negative (ground) cable from
the
battery
before servicing
any
component
on the
column.

CAUTION:
Do not
attempt
to remove the
pins
to
dis­

semble
the
tilting
mechanism. Damage
will
occur.

Safety goggles should be worn at all times
when involved with steering column service. STEERING WHEEL
REMOWAL
(1) Make sure the front wheels are in the straight
ahead position.
(2) Disconnect the negative (ground) cable from
the battery.
(3) Remove the horn pad components (Fig. 2).
(4) Remove the steering wheel retaining nut. Score
or paint alignment marks on the column shaft and steering wheel (if none exist) for installation refer­

ence.

marks or master splines aligned. (2) Pull the speed control wires through the lower,
larger hole in the steering wheel. Pull the horn wire
through the smaller hole at the top. Ensure the
wires are NOT pinched.
(3) Install the retaining nut and tighten to 61 N«m
(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. 2).

CLOCKSPRING

REMOVAL
(1) Place the front wheels in the straight ahead po­
sition before starting the repair.
(2) Disconnect battery negative cable and isolate.
(3) Remove the steering wheel, refer to Steering
Wheel Removal. (4) Remove upper and lower steering column
shrouds to gain access to the clockspring wiring.
(5) Release wire connector at clockspring. (6) Pull clockspring assembly from column by lift­
ing locking fingers as necessary. The clockspring
cannot be repaired, and must be replaced if faulty.

INSTALLATION
(1) Snap clockspring assembly onto column. If
clockspring is not properly positioned, follow the cen­
tering procedures before installing steering wheel.
(2) Connect the wire connector to the clockspring.

WARNING: ENSURE CLOCKSPRING WIRE CON­ NECTION
IS
COMPLETELY SEATED.
THE

THE
MODULE.

(3) Install upper and lower steering column
shrouds. Be sure wiring is inside of shrouds and not
pinched. (4) Install the steering wheel and air bag module,
refer to Steering Wheel Installation.

CENTERING
PROCEDURE
If the rotating tape within the clockspring is not
positioned properly, the clockspring may fail during
use.
The following procedures MUST BE USED to
center the clockspring.
(1) Place the front wheels in the straight ahead po­
sition before starting the procedure. (2) Depress the 2 locking tabs to disengage the
locking mechanism (Fig. 4).

(3) Keeping the mechanism disengaged, rotate the
clockspring rotor in the CLOCKWISE DIRECTION
to the end of the travel. Do not apply excessive
torque.
