axle

The
rear
axle

is
of
a

semi

floating

type
The
axle

housing
is
a

press
steel

Banjo
type
housing
It
is

light
in

weight
and
is

sufficiently

strong
to
withstand
all
torsional

and

bending
loads

The

rear
wheel

bearings
are
of

presea1ed
types
There

fore
no

frequent
lubricating
service
is

required
However

when
the
rear

axle
is

disassembled
the
wheel

bearings

should
be

packed
with
an

approved
grease

prior
io
the
