FRONT AXLE -General Information26-2
GENERAL INFORMATION
The front axle consists of the front hubs, knuckles,
drive shaft, wheel bearings, ball joints, front
differential, and freewheel clutch.
The features are:
DThe structural method of press fitting unit
bearing into the front hub is applied.
DThe wheel bearing uses a taper roller unit
bearing. For vehicles with ABS, a rotor for
detecting the wheel speed is press-fitted to
the U.J. outer wheel.
DDrive shafts incorporate U.J.-B.J.-type constant
velocity ball joint has high power transmission
efficiency and reduces vibration and noise.NOTE
U.J. is an abbreviation of Under cut Joint.
DA vacuum-type freewheel clutch has been
adopted in the freewheel mechanism. Its
solenoid valve and actuator switch powertrain
between 2WD and 4WD.
DThe differential support method is a four-point
elastic support method which reduces vibration
and noise.
