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
oil
as

should
be

greased
up
with
wheel

bearing
grease
every
50
000
