INSPECTION AND REPAIR
WARNING
THE INFLATOR MODULE SHOULD ALWAYS BE CARRIED
WITH THE URETHANE COVER AWAY FROM YOUR BODY
AND SHOULD ALWAYS BE LAID ON A FLAT SURFACE
WITH THE URETHANE SIDE UP. THIS IS NECESSARY
BECAUSE A FREE SPACE IS PROVIDED TO ALLOW THE
AIR CUSHION TO EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL DEPLOYMENT. OTHERWISE, PERSONAL
INJURY MAY BE RESULT.
INSTALLATION
3. Inflator Module
CAUTION:
·Never use the air bag assembly from another vehicle.
Use only the air bag assembly for "UBS".
·When replace the inflator module, use only same parts
number assembly. If different parts number assembly is
installed, the air bag system can not function correctly
because it has different characteristic.
2. Module Connector
Support the module and carefully connect the
module connector.
NOTE:
Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire
from being pinched.
The Inflator module consists of a cover, air bag,
inflator, and retainer. Inspect the Inflator module
mainly for the following:
1) Check for holes, cracks, severe blemishes and
deformation on the cover.
2) Check that the retainer is not deformed.
3) Check for defects such as damage and breakage
in the lead wire of the squib.
If an abnormality is found as the result of the
inspection, replace the Inflator module with a new
one.

REMOVAL
Preparation:
1) Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
2) Turn the ignition switch to "LOCK".
3) Disconnect the battery ground cable, and wait at least
5 minutes.
4) Disconnect the yellow 2way SRS connector located
under the steering column. CAUTION:
Once the steering column is removed from the vehicle, the column is extremely suspectible to
damage. Dropping the column assembly on its end could collapse the steering shaft or loosen the
slide block which maintains column rigidity. Leaning on the column assembly could cause the jacket
to bend or deform. Any of the above damage could impair the column's collapsible design. If it is
necessary to remove the steering wheel, use only the specified steering wheel puller. Under no
conditions should the end of the shaft be hammered upon, as hammering could loosen slide block
which maintains column rigidity.

2A – 76 SUPPLEMENTAL RESTRAINT SYSTEM STEERING WHEEL & COLUMN
GENERAL DESCRIPTION
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize
the possibility of injury to the driver of the
vehicle.
2. The ignition switch and lock are mounted
conveniently on the column.
3. With the column mounted lock, the ignition
and steering operation can be locked to
prevent theft of the vehicle.The column may be disassembled and
reassembled. To insure the energy absorbing
action, it is important that the specified screws,
bolts and nuts be used only as designated and that
they are tightened to the specified torque.
When the column is removed from the vehicle, a
sharp blow on the end of steering shaft leaning on
the column assembly, or dropping the assembly
could shear or loosen the fasteners that maintain
column rigidity.

3C – 2 FRONT SUSPENSION
GENERAL DESCRIPTION
The front suspension is designed to allow each
wheel to compensate for changes in the road
surface level without greatly affecting the opposite
wheel. Each wheel is independently connected to
the frame by a steering knuckle, ball joint
assemblies, and upper and lower control arms.
The front wheels are held in proper relationship to
each other by two outer track rods which are
connected to steering arms on the knuckles and to
a center track rod.
All models have a front suspension system
consisting of control arms, stabilizer bar, shock
absorber and a torsion bar. The front end of the
torsion bar is attached to the lower control arm.
The rear of the torsion bar is mounted into a height
control arm at the crossmember. Vehicle trim
height is controlled by adjusting this arm.
Shock absorbers are mounted between the
brackets on the frame and the lower control arms.The lower portion of each shock absorber is
attached to the lower control arm by a bolt and nut.
The upper portion of each shock absorber extends
through a frame bracket and is secured with two
rubber bushings, three retainers and a nut.
Ball joint assemblies are bolted to the outer end of
the upper and lower control arm and are attached
to the steering knuckle by nuts and cotter pins.
The inner ends of the upper control arm have
pressed in bushings. Bolts passing through the
bushing, attach the control arm to the frame. The
inner ends of the lower control arm are attached to
the frame by bolts passing through the bushings,
which are pressed in the frame.
Side roll of the front suspension is controlled by a
spring steel stabilizer bar. It is mounted in rubber
bushings, which are held to the crossmember by
brackets. The ends of the stabilizer are connected
to the lower control arms by link bolts isolated by
rubber bushings.
