1. OVERVIEW
The axle is the device of transferring the drive power from the engine to the wheels; its inside is fitted to
the side gear spline of the differential gear and outside is connected to the drive wheels. The axles in
front and rear of vehicle are known as the front axle and rear axle respectively.
For the FR (Front engine, Rear wheel drive) type vehicle driven by the rear wheels, the drive power is
basically transferred to the rear wheels in the following order in 2WD mode: Engine-
>Clutch→Transmission→Propeller shaft (Rear propeller shaft)→Final reduction gear (Rear
axle)→Rear axle shaft→Rear wheels. In 4WD mode, the drive power to the rear wheels is
distributed to the front wheels in order of Front propeller shaft->Front axle->Front axle shaft->Front
wheel via the T/C assembly. And, 4WD solenoid valve releases the vacuum and engage the locking
hub actuator to the LH/RH front hub end gear to transfer the drive power of the axle shaft to the front
wheels.
The front axle and front axle shaft are used in only 4WD model. The rear axle has the independent
rear drive axle (IRDA) which is used on the independent rear suspension (IRS).

Operation ▶
Description Mode Conditions
Driving mode 2H 2 Wheel drive
(rear wheel)Rear-wheel drive mode. This is used under normal
or high-speed driving conditions on public roads or
highways.
4H 4 Wheel drive
(high speed)This is used under sandy, muddy or snow-covered
road conditions
4 L 4 Wheel drive
(low speed)This is used for maximum traction.
When cornering with low speed in 4WD condition,
there could be tire dragging, some
mechanical shocks and resistances in vehicle’s
drive train. These are normal conditions due to
internal resistance in the drive train when the
4WD system is properly working

To make the mode change easily, stop the
vehicle on level ground and turn the mode
switch to the desired position and move the
shift lever to "N"-"R"-"N" while depressing the
brake pedal. For Automatic Transmission:
Stop the vehicle on level ground and move the
gear selector lever into the “N”
position. Turn
the switch to the desired position. -
For Manual Transmission:
Stop the vehicle on level ground and move the
gear selector lever into the “N” position.
Then turn the switch to the desired position
while depressing the clutch pedal. -

Power Flow ▶
The driving force is pass through 4WD High magnetic clutch in transfer case and is distributed
on front wheels and rear wheels (50;50).
