STEERING
DESCRIPTION
The
steering
system
consists
of
recirculating
ball
type
gear
box
and
parallelogram
linkage
These
systems
give
good
response
light
handling
and
utmost
durability
Moreover
the
steering
linkage
is
equipped
with
a
torsion
rubber
system
idler
arm
which
absorbs
shock
from
the
wheel
Check
the
lubricant
of
gear
box
every
10
000
km
6
000
miles
and
replenish
recommended

should
be
greased
up
with
wheel
bearing
grease
every
50
