Features
• Unit-design, double angular ball bearings with low rotational resistance have been adopted for the front and rear axles.
• Unit bearings that require no preload adjustment have been adopted for the front and rear wheels.
• The following parts have been adopted to reduce vibration and noise:
-
― Bell-shaped constant velocity joint has been adopted for the wheel-side joint of the front drive shaft.
― A tripod-shaped constant velocity joint has been adopted for the differential-side joint of the front drive shaft.
― For 4WD vehicles, bell-shaped constant velocity joint has been adopted for the wheel-side joint of the rear drive shaft.
― For 4WD vehicles, a tripod-shaped joint has been adopted for the differential-side constant velocity joint.
― For 4WD vehicles, 2-part, 1-joint type propeller shaft with middle shaft bearing has been adopted.
• For 4WD vehicles, the following parts have been adopted to improve off-road mobility and handling stability:
-
― Electronic 4WD control system which automatically and optimally controls drive torque distribution for the front and rear wheels.
― Rear differential which integrates the coupling component to reduce size and weight.
• Ball bearings/tandem ball bearings with low rolling resistance have been adopted for the inside of the rear differential and transfer.
