FRONT AXLE ± General Information
26-2
GENERAL INFORMATION
The front axle consists of the hub assembly, drive
shaft, inner shaft, front differential, and
free-wheeling clutch.
The features are:
D The free-wheeling mechanism enables 2WD
and 4WD to be switched over during driving,
thus improving fuel efficiency and reducing
vibration at the 2WD mode.
D The drive shaft uses a B.J.-D.O.J.-type constant
velocity ball joint which has high power
transmission efficiency and reduces vibration
and noise.
D For vehicles with ABS, the ABS rotor for
detecting the wheel speed has been pressed
in the B.J. joint.
D The axle is supported by the ball bearing and
the front hub, which is pressed in the knuckle
axle housing.
D The ball bearing is of a double-row angular
contact ball bearing which features high thrust
load resistance.
D The differential carrier is supported elastically
at three points, thus reducing vibration and
noise.
