Rear Drive Shaft Assembly Removal and
Installation
S6RW0D3126002
Removal
1) Hoist vehicle and remove rear wheel.
2) Undo caulking of drive shaft nut (1) and then remove
drive shaft nut with pull up parking brake lever.
3) Remove rear drive shaft flange nuts (1), and then
remove rear drive shaft.
Installation
Install drive shaft assembly by reversing removal
procedure and noting the following points.
CAUTION!
• Protect boots from any damage,
preventing them from unnecessary contact
while installing drive shaft.
• Do not hit joint boot with hammer.
Inserting joint only by hands is allowed.

• Tighten each nuts to specified torque referring to
“Rear Drive Shaft Components”.
Rear Drive Shaft Disassembly and ReassemblyS6RW0D3126003
Disassembly
Refer to “Front Drive Shaft Disassembly and
Reassembly” note the following point which is different
from the front drive shaft is described.
• Remove differential side boot big band and small
band as follows.
– For boot big band (and small band) without joint [A]:
Remove boot big band (and small band) by tapping
boot and band with plastic hammer. If it is hard to
remove boot big band (and small band), cut it using
a nipper or an iron saw with care not to damage
joint housing.
– For boot big band (and small band) with joint [B]:
Draw hooks of boot big band (and small band)
together and remove band.

General Description
Rear Differential DescriptionS6RW0D3201001
The differential assembly uses a hypoid bevel pinion and gear.
The differential assembly is decisive in that the drive power is concentrated there. Therefore, use of genuine parts and
specified torque is compulsory. Further, because of sliding tooth meshing with high pressure between hypoid bevel
pinion and gear, it is mandatory to lubricate them by hypoid gear oil.
Coupling DescriptionS6RW0D3201002
Coupling is installed in the forward of Rear differential. The road situation and driving are judged with 4WD control
module based on information from sensor and each control module, and the distribution of driving force of the front
and rear wheel has been changed by controlling the current to coupling. Coupling air temperature sensor is installed in
coupling case and measures the temperature in coupling.
4WD system has three driving positions (2WD, 4WD-auto, 4WD-lock). The position corresponding to the running
situation can be selected by 2WD/4WD switch.

4WD Control System DescriptionS6RW0D3201004
4WD Shift Control
The 4WD control module operates the coupling assembly according to the 2WD/4WD switch operation to the selected
position (2WD, 4WD-auto or 4WD-lock). Also, the 4WD control system has 4WD AUTO indicator and 4WD LOCK
indicator in order to inform the 4WD control system condition.
Indicator Operation
The 4WD control module output operation signal of the 4WD AUTO indicator and the 4WD LOCK indicator. Indicators
as follows in order to inform what state the 4WD control system is.
