Rear Differential Description

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 Description

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.
