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.

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 STEERING WHEEL PAD AND SPIRAL CABLE
RS−15
1996 LAND CRUISER (RM451U)
(1) Install the 2 bolts with washers in the 2 bolt holes in
the steering wheel pad.
Bolt:
L: 35. mm (1.387 in.)
M: 6.0 mm (0.236 in.)
Pitch: 1.0 mm (0.039 in.)
NOTICE:
Tighten the bolts by hand until the bolts become diffi-
cult to turn.
Do not tighten the bolts too much.
(2) Using 3 wire harnesses, wind the wire harness at least 2 times each around the bolts installed on the
left and right sides of the steering wheel pad.
CAUTION:
Tightly wind the wire harness around the bolts so that
there is no slack.
If there is slack in the wire harness, the steering wheel
pad may come loose due to the shock when the air-
bag is deployed. This is highly dangerous.
(3) Face the upper surface of the steering wheel pad
upward. Separately tie the left and right sides of the
steering wheel pad to the disc wheel through the
hub nut holes. Position the steering wheel pad con-
nector so that it hangs downward through a hub
hole in the disc wheel.
CAUTION:
Make sure that the wire harness is tight. It is very dan-
gerous when looseness in the wire harness results in
the steering wheel pad coming free through the shock
from the airbag deploying.
Always tie down the steering wheel pad with the pad
side facing upward. It is very dangerous if the steer-
ing wheel pad is tied down with the metal surface fac-
ing upward as the wire harness will be cut by the
shock from the airbag deploying and the steering
wheel pad will be thrown into the air.
NOTICE:
The disc wheel will be marked by airbag deployment, so
when disposing of the airbag use a redundant disc wheel.

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers \
indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated \
to apply differential
power to the differential, the differential locks and the indicator lamp\
light up.

HINT:
The clamps opening must be positioned at the rear of the tie rod
end face within 60 °±10° from the vehicle axis.
6. INSPECT WHEEL ANGLE
(a) Remove the caps of the knuckle stopper bolts and check the steering angles.
(b) Turn the steering wheel fully, and measure the turning angle.
Inside wheel32°00’ − 35°00’
Outside wheel31 °00’ (Reference)
HINT:
When the steering wheel is fully turned, make sure that the
wheel is not touching the body or brake flexible hose.
If maximum steering angles differ from the standard value, ad-
just the wheel angle with the knuckle stopper bolts.
Torque: 44 N·m (450 kgf·cm, 33 ft·lbf)
If the wheel angle still cannot be adjusted within limits, inspect
and replace damaged or worn steering parts.
