REMOVAL AND INSTALLATION
Differential Mountings
1) Lift up vehicle and turn steering wheel all way to the right.
2) Separate mounting bracket R from differential housing by re-
moving bolts from its lower part.
3) Remove mounting bracket R by removing mounting front bolt
from its upper part.
4) Remove mounting bracket L by removing upper and lower fas-
tening bolts.
5) Check conditions of each bush. If it is damaged or deteriorated,
drive it out with special tools and press for replacement.

KEY CODING
KEY USAGE AND IDENTIFICATION
Key is used for ignition and door lock cylinder. Keys are cut on both
edges to make them reversible.
Key identification is obtained from five character key code stamped
on key code tag. Using this key code, key code cutting combination
can be determined from a code list (available to owners of key cut-
ting equipment from suppliers).
If key codes are not available from records or tags, key code can
be obtained from the right hand door lock cylinder (if lock has not
been replaced). Lock cylinders supplied by the factory as service
parts are unmarked.
If original key is available, key code cutting combination can be de-
termined by laying key.

AIR BAG SYSTEM 10B-7
Special Tool (Air Bag Driver/Passenger Load Tool)
(B): 09932-75010
This tool is used only when called for in this section. It is used as
a diagnostic aid and safety device to prevent inadvertent air bag (in-
flator) module deployment and seat belt pretensioner activation.
The load tool has three connectors attached to its case are electri-
cally functional and serve as resistive load substitutions.
No more than two connectors are used at any time.
One of connectors (ªAº: BASE OF COLUMN) is used to substitute
the load of the driver air bag (inflator) module and the contact coil
assembly when it is connected at the base of the column to the air
bag wire harness.
Another connector (ªBº: STEERING WHEEL) is used to substitute
the load of followings.

Driver air bag (inflator) module when it is connected at the top of
the column to the contact coil assembly.

Passenger air bag (inflator) module when it is connected to the
air bag harness connector for passenger air bag (inflator) module.

Driver and passenger seat belt pretensioner when it is connected
to air bag harness connector for driver and passenger seat belt
pretensioner.
The third connector (ªCº: PASSENGER INFLATOR) is not used.
By substituting the resistance of the load tool when called for, a de-
termination can be made as to whether an inflator circuit compo-
nent is causing system malfunction and which component is caus-
ing the malfunction.
The load tool should be used only when specifically called for in the
diagnostic procedures.
