5. SELECT SPIDER BEARING
Select the bearing according to whether or not there is a drill
mark on the yoke section.

HINT:
At time of the reassemble, there are 2 types of rear propeller
shafts, type A and type B. Referring to the illustration, measure
the distance between the welding points X and Y to identify
which of the 2 types is used for the vehicle.
6. INSTALL SPIDER BEARING
(a) Apply MP grease to a new spider and bearings.
NOTICE:
Be careful not to apply too much grease.
(b) Align the matchmarks on the yoke and flange.
(c) Fit the spider into the yoke.
(d) Using SST, install the bearings on the spider. SST 09332−25010
(e) Using SST, adjust both bearings so that the snap ring grooves are at maximum and equal widths.

SUPPLEMENTAL RESTRAINT SYSTEM SRS AIRBAG

1996 LAND CRUISER (RM451U)
SRS AIRBAG
PRECAUTION
NOTICE:
The LAND CRUISER is equipped with an SRS , which comprises a driver airbag \
and a front pas-
senger airbag. Failure to carry out service operations in the correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serio\
us accident. Further,
if a mistake is made in servicing the SRS, it is possible the SRS may fail to\
operate when re-
quired. Before performing servicing (including removal or installation \
of parts, inspection or
replacement), be sure to read the following items carefully, then follow the correct procedure
described in the repair manual.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the mos\
t impor-
tant source of information when troubleshooting. When troubleshooting th\
e SRS, always in-
spect the DTCs before disconnecting the battery.
Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front
passenger airbag assembly, and airbag sensor assembly should be inspected (See pages
RS−9 , RS−23 and RS−34 )
Never use SRS parts from another vehicle. When replacing parts, replace them with \
new parts.
Never disassemble and repair the steering wheel pad, front passenger airbag assembly , or air-
bag sensor assembly in order to reuse it.
If the steering wheel pad, front passenger airbag assembly or airbag sen\
sor assembly have
been dropped, or if there are cracks, dents or other defects in the case, br\
acket or connector,
replace them with new ones.
Use a volt/ohmmeter wi th high impedance (10 k Ω/V minimum) for troubleshooting the system’s
electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.
After work on the SRS is completed, check the SRS warning light (See pa\
ge DI−240).
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.
CAUTION:
Work must be started after 90 seconds from the time the ignition switch is t\
urned to the ”LOCK”
position and the negative ( −) terminal cable is disconnected from the battery.
(The SRS is equipped with a back− up power source so that if work is started within 90 seconds
of disconnecting the negative ( −) terminal cable of the battery, the SRS may be deployed.)
When the negative (−) terminal cable is disconnected from the battery, the memory of the clock
and audio system will be canceled. So before starting work, make a record o\
f the contents mem-
orized in the audio memory system. When work is finished, reset the audio syst\
ems as they
were before and adjust the clock. To avoid erasing the memory of each memory system, never
use a back−up power supply from outside the vehicle.
Before repairs, remove the airbag sensor if shocks are likely to be applied to the senso\
r during
repairs.
Do not expose the steering wheel pad, front passenger airbag assembly, or airbag sensor as-
sembly directly to hot air or flames.

SUPPLEMENTAL RESTRAINT SYSTEM SRS AIRBAG
1996 LAND CRUISER (RM451U)
OPERATION
1. STEERING WHEEL PAD (with AIRBAG)
The inflater and bag of the SRS are stored in the steering wheel
pad and cannot be disassembled. The inflater contains a squib,
igniter charge, gas generant, etc., and inflates the bag when
instructed by the airbag sensor assembly.
2. SPIRAL CABLE (in COMBINATION SWITCH)
A spiral cable is used as an electrical joint from the vehicle body
side to the steering wheel.
3. FRONT PASSENGER AIRBAG ASSEMBLY
The inflater and bag of the SRS are stored in the front passen-
ger airbag assembly and cannot be disassembled.The inflater
contains a squib, igniter charge, gas generant, etc., and inflates
the bag when instructed by the airbag sensor assembly.
4. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It
goes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly. In normal
operating condition when the ignition switch is turned to the
ACC or ON position, the light goes on for about 6 seconds and
then goes off.
5. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
console box. The airbag sensor assembly consists of an airbag
sensor, safing sensor, diagnosis circuit and ignition control,
drive circuit, etc.
It receives signals from the airbag sensors and judges whether
the SRS must be activated or not.
