General Description
Front Drive Shaft ConstructionS6RW0D3111001
A constant velocity ball joint is used on the wheel side of both right and left side drive shaft assemblies. For A/T
vehicle, a tripod type constant velocity joint is used on the differential side and center shaft side. For M/T vehicle, a
double offset type constant velocity joint (DOJ) is used on the differential side and center shaft side. The drive shaft
can slide through the tripod joint or the double offset joint (DOJ) in the extension/contraction direction.

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.

Visual InspectionS6RW0D3204004
Check the following parts and systems visually.
DTC CheckS6RW0D3204005
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector
(DLC) (1) located on underside of instrument panel.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on
SUZUKI scan tool and print it or write it down. Refer
to SUZUKI scan tool operator’s manual for further
details.
If communication between SUZUKI scan tool and
4WD control module is not possible, check if
SUZUKI scan tool is communicable by connecting it
to 4WD control module in another vehicle. If
communication is possible in this case, SUZUKI
scan tool is in good condition. Then check data link
connector and serial data line (circuit) in the vehicle
with which communication was not possible.
5) After completing the check, turn ignition switch OFF
and disconnect SUZUKI scan tool from data link
connector (DLC).
DTC ClearanceS6RW0D3204006
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector
(DLC) (1) located on underside of instrument panel.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Erase DTC according to instructions displayed on
SUZUKI scan tool. Refer to SUZUKI scan tool
operator’s manual for further details.
5) After completing clearance, turn ignition switch OFF
and disconnect SUZUKI scan tool from data link
connector (DLC).
6) Perform “DTC Check” and confirm that NO CODES
is displayed.
NOTE
DTC stored in 4WD control module memory
are also cleared in the following cases. Be
careful not to clear them before keeping their
record.
• When power to 4WD control module is cut
off (by disconnecting battery cable,
removing fuse or disconnecting 4WD
control module connectors).
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles.
Inspection Item Referring
• Rear differential oil ---- level, leakage “Rear Differential Oil Change”
• Transfer gear oil ---- level, leakage “Transfer Oil Change in Section 3C”
• Manual transmission oil ---- level, leakage “Manual Transaxle Oil Change in Section 5B”
• Rear differential mounting(s) ---- wear and looseness

Transfer
General Description
Transfer DescriptionS6RW0D3301001
The transfer is mounted on transaxle case by fastening bolt with reduction drive gear in transfer and differential case in
transaxle coupled by involute spline. Driving force from transaxle is transmitted to propeller shaft through reduction
drive gear, reduction driven gear and bevel gear of transfer. As bevel gears, which change the direction of driving
torque axis to the direction of the angle with 90 degrees, hypoid gears are provided. Hypoid gears have an advantage
of preventing gear noise, at the same time, they require accurate adjustment of tooth contact and backlash.
