DRIVELINE/AXLE

id030000100400


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.
