DISASSEMBLY
1. CHECK RUNOUT OF COMPANION FLANGE
Using a dial indicator, measure the runout of the companion
flange vertical and lateral.
Maximum
Vertical runout: 0.09 mm (0.0035 in.)
Lateral runout: 0.09 mm (0.0035 in.)
If the runout is greater than the maximum, replace the compan-
ion flange.
2. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout.
Maximum runout: 0.05 mm (0.0020 in.)
3. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash.
Backlash:
2WD: 0.08 − 0.13 mm (0.0031 − 0.0051 in.)
4WD: 0.13 − 0.18 mm (0.0051 − 0.0071 in.)
If the backlash is not within specification, adjust the side bear-
ing preload or repair if necessary.
HINT:
Measure from 3 or more places on the circumference of the ring
gear.
4. CHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See page SA−145)
5. CHECK SIDE GEAR BACKLASH
Using a dial indicator, measure the side gear backlash with
holding one pinion gear toward the case.
Backlash: 0.05 − 0.20 mm (0.0020 − 0.0079 in.)
If the backlash is not within the specification, install the side
gear thrust washers of differential thickness.

BRAKE SYSTEM
GENERAL DESCRIPTION
Care must be taken to replace each part properly as it could affect the performance of the brake
system and result in a driving hazard. Replace the parts with parts having the same part number
or equivalent.
It is very important to keep parts and the area clean when repairing the brake system.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.

SRS AIRBAG
PRECAUTION
NOTICE:
The TOYOTA T100 is equipped with SRS, which comprises a driver airbag. Failure to carry out
service operations in the correct sequence could cause the SRS to unexpectedly deploy during
servicing, possibly leading to a serious accident. Further, if a mistake is made in servicing the
SRS, it is possible that the SRS may fail to operate when required. Before performing servicing
(including removal or installation of parts, inspection or replacement), be sure to read the fol-
lowing items carefully, then follow the correct procedures described in the repair manual.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the 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, air-
bag sensor assembly and front airbag sensor should be inspected (See page RS−9, RS−23 and
RS−28).
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
Never disassemble and repair the steering wheel pad, airbag sensor assembly or front airbag
sensor in order to reuse it.
If the steering wheel pad, airbag sensor assembly or front airbag sensor has been dropped, or
if there are cracks, dents or other defects in the case, bracket or connector, replace them with
new ones.
Use a volt/ohmmeter with high impedance ( 10 kΩ/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, perform the SRS warning light check or SRS side airbag
warning light check (See page DI−365).
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 when the ignition switch is turned 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
from 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 of the contents mem-
orized in the audio memory system. When work is finished, reset the audio systems as they
were before and adjust the clock. To avoid erasing the memory in 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 sensor during
repairs.
Do not expose the steering wheel pad, airbag sensor assembly or front airbag sensor directly
to hot air or flames.

INSPECTION
1. VEHICLES NOT INVOLVED IN A COLLISION
(a) Do a diagnostic system check.
(See page DI−365)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check for cuts, minute cracks or marked discoloration on
the steering wheel pad top surface and in the grooved
portion.
2. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Do a diagnostic system check.
(See page DI−365)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check for cuts, minute cracks or marked discolor-
ation on the steering wheel pad top surface and in
the grooved portion.
Check for cuts and cracks in wire harness, and chip-
ping in connectors.
Check for the deformation of the horn button con-
tact plate of the steering wheel.
HINT:
If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.

There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.
CAUTION:
For removal and installation of the steering wheel pad, see
the SR section and be sure to follow the correct procedure.

hicle.
Check for the deformation on the horn button con-
tact plate of the steering wheel.
Check for the damage to the spiral cable connector
and wire harness.
HINT:
If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.

INSTALLATION
NOTICE:
Never use SRS parts from another vehicle. When re-
placing parts, replace with new ones.
Never reuse the airbag sensor assembly involved in
a collision when the airbag has deployed.
Never repair a sensor in order to reuse it.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Using a torx wrench, install the airbag sensor assembly
with 3 screws.
Torx wrench: T40 (Part No. 09042−0020 or locally
manufactured tool)
Torque: 21 N·m (210 kgf·cm, 15 ft·lbf)
(b) Connect the connector.
NOTICE:
Installation of the connector is done with the sensor
assembly installed. Make sure the sensor assembly
is installed to the specified torque.
If the sensor assembly has been dropped, or there are
cracks, dents or other defects in the case, bracket or
connector, replace the sensor assembly with a new
one.
When installing the sensor assembly, take care that
the SRS wiring does not interfere with other parts and
is not pinched between other parts.
After installing, shake the sensor assembly to check
that there is no looseness.
2. INSTALL REMOVED PARTS
