FRONT AXLE ± General Information26-2
GENERAL INFORMATION26100010111
2WD
The front hub assembly which uses a double taper
roller bearing is mounted on the knuckle spindle.For vehicles with ABS, a rotor for detecting the
wheel speed is press-fitted into the front hub.
4WD
The front axle consists of the hub assembly, drive
shaft, inner shaft, front differential, freewheel clutch
assembly and actuator. The features are:

The wheel bearing uses a double taper roller
bearing. For vehicles with ABS, a rotor for
detecting the wheel speed is bolted to the brake
disc.

Drive shafts of almost identical length reduce
torque steer. In addition, a D.O.J.-B.J.-type
constant velocity ball joint has high power
transmission efficiency and reduces vibration
and noise.
A vacuum-type freewheel clutch has been
adopted in the freewheel mechanism. Its
solenoid valve and actuator switch powertrain
between 2WD and 4WD.

There are two types of differential gear. The
difference between them is gear ratio.
