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.

― For ATX vehicles, to absorb idling vibration occurring while the vehicle is stopped in the D position, a tripod-shaped joint has been adopted for the differential-side constant velocity joint, reducing vibration and noise.

― For MTX vehicles, a double offset-type 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.
