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

• Fit differential side boot as follows.
– Fit boot (1) to grooves of shaft and housing (2)
adjust length to specification below.
– Insert screw driver into boot and allow air to enter
boot so that air pressure in boot becomes the same
as atmospheric pressure.

CAUTION!
• Bend each boot band against forward
rotation.
• Do not squeeze or distort boot when
fastening it with bands. Distorted boot
caused by squeezing air may reduce its
durability.

– Place differential side boot new big band (3) and
new small band onto boot putting band outer end
(1) against forward rotation (2) as shown in figure.
– Fasten differential side boot new big band (1) and
new small band by drawing hooks (2) with special

Precautions
Precaution for Rear Differential Oil LeakageS6RW0D3200001
Whenever vehicle is hoisted for any other service work than oil change, also be sure to check for oil leakage.
Precautions in Diagnosing TroubleS6RW0D3200002
• Do not disconnect the following parts before confirming diagnostic information (DTC, etc.) stored in 4WD control
module memory. These actions will erase memorized information in 4WD control module memory.
– Disconnection of coupler from 4WD control module
– Disconnection of battery cable from battery
– Disconnection of ground wire harness of 4WD control module
– Disconnect main fuse from fuse box
• Diagnostic information stored in 4WD control module memory can be cleared as well as checked by using SUZUKI
scan tool. Before using scan tool, read its Operator’s (Instruction) Manual carefully to have good understanding as
to what functions are available and how to use it.
• Be sure to read “Precautions for Electrical Circuit Service:” before inspection and observe what is written there.

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.
