Front Differential Construction

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 bevel pinion and
gear, it is mandatory to lubricate them by hypoid gear oil.
