Front Differential Construction
The front differential assembly for 4WD model 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.
The hypoid gears have an advantage of preventing gear noise, at the same time, they require accurate adjustment of tooth contract and backlash.
