handle and air ducts. On all models, remove any necessary cable bands,
and remove steering column switch. To install, reverse removal
procedure.
Removal (Stealth & 3000GT)
1) Disconnect negative battery cable. Wait 30 seconds, and
then remove air bag module mounting nut from back side of module. To
remove clockspring connector from air bag module, force lock outward
and pry it using a flat screwdriver. Ensure no undue force is exerted
on connector when it is removed. Remove air bag module, and store it
face up. See Fig. 7.
CAUTION: Wait at least 30 seconds after disconnecting battery cable
before continuing servicing.
2) Remove steering wheel and knee protector. Remove upper and
lower column covers. Remove air ducts. Remove right and left steering
column switches.
WARNING: DO NOT hammer on steering wheel. Collapsible steering column
mechanism may be damaged.
Installation
1) To install, reverse removal procedure. Before installing
steering wheel, center clockspring by lining up NEUTRAL mark of
clockspring with mark on steering column. To complete installation,
reverse removal procedure. DO NOT reconnect negative battery cable
until air bag module is installed.
2) After installation is complete, turn ignition on from
passenger side of vehicle. Supplemental Restraint System (SRS) light
on dash should come on for approximately 7 seconds. If SRS light does
not come on, stays on or flashes, repair air bag system.

BALL JOINTS
Before requiring or suggesting ball joint replacement, the
approved OEM procedure must be used to measure ball joint wear. The
measurement(s) obtained, along with the vehicle manufacturer's
specifications, must be noted on the inspection report. Some states
require that these measurements also appear on the invoice.
NOTE: The term "perceptible movement," defined as any visible
movement in any direction, has been the industry standard
for determining the need for replacement of follower ball
joints. Some vehicle manufacturers are now publishing
specifications for follower ball joints that were

WHEELS AND TIRES
TIRES
These guidelines do not apply to split rims. Some vehicle
manufacturers restrict replacement of tires to specific brands, types,
or sizes.
WARNING: High pressure temporary compact spare tires should not be
used with any other rims or wheels, nor should standard
tires, snow tires, wheel covers, or trim rings be used
with high pressure compact spare rims or wheels.
Attempting to mount a tire of one diameter on a wheel of
a different diameter or flange type may result in serious
injury or death.
WARNING: Only specially trained persons should dismount or mount
tires. Explosions of tire and wheel assembly can result
from improper mounting, possibly causing serious injury
or death.
WARNING: Consult the vehicle owner's manual or vehicle placard for
correct size, speed rating, designation, and cold
inflation pressure of the original tires. DO NOT exceed
the maximum load or inflation capacity of the tire
specified by the Tire and Rim Association
WARNING: When replacing tires, it is suggested that the
replacement tires match or exceed the OEM speed rating
designation. If tires of different speed rating
designations are mixed on the same vehicle, the tires may
vary in handling characteristics. DO NOT mix different
speed rating designations on the same axle.
WARNING: DO NOT mix radials with non-radial tires on the same
axle, as this may affect vehicle handling and stability.
If radial tires and bias or bias-belted ply tires are
mixed on the same vehicle, the radials must be on the
rear. High-pressure temporary compact spare tires are
exempt from this rule.
WARNING: DO NOT mix size or type (all season, performance, mud and
snow) of tires on the same axle.

\
\
\
\
\
\
WHEELS (RIMS)
WARNING: Mounting a regular tire on a high-pressure compact spare
wheel is not permitted. Attempting to mount a tire of one
diameter on a wheel of a different diameter or flange
type may result in serious injury or death. If the wheel
identification stamp is not legible, or cannot be found,
do not use the wheel until the size and type have been
properly identified. Wheels of different diameter,
offset, or width cannot be mixed on the same axle. Bead
seat tapers cannot be interchanged.
