FRONT AXLE AND FINAL DRIVE

DESCRIPTION AND OPERATION
DESCRIPTION
The welded steel front axle casing houses a separate
spiral bevel type differential unit, which is off-set to the
right of the vehicle centre line. The differential unit
drives the front wheels via the axle shafts and
constant velocity joints which are totally enclosed in
the spherical and swivel housings.
The front wheels are pivoted on tape roller bearings at
the top and bottom of the swivel housing. The wheel
hubs on all axles are supported by two taper bearings
and driven by drive flanges which are splined to the
one piece, stub shaft/constant velocity joint.
