Front coil spring assembly
The coil spring is made by winding solid steel rod to form
the coil shape. Its energy absorption rate per weight is
higher than that of the leaf spring and it allows to absorb
small vibration properly resulted in keeping the ride
comforts. Therefore, it's difficult to make an effect on
vibration damping because there is not any friction
between coils.

6. REAR SUSPENSION COMPONENT LAYOUT
Multi-link type suspension is the independent suspension. It provides good ride comfort and drivability
by reducing the coil spring weight. Also, it increases the space for passenger compartment by lowering
the floor.
This type of suspension consists of multiple links such as trailing arm, upper arm, lower arm and track
rod.
Shock absorber assembly
This vehicle uses the gas
shock absorber. This
relieves the vertical
vibrations of vehicle to
provide ride comforts,
prevents the spring break,
enhances drivability, and
extends the life span of
steering components.
Upper arm assembly
Upper arm is installed between knuckle and sub
frame and controls the lateral load and vehicle
height.
Trailing arm assembly
Trailing arm is installed between knuckle and
vehicle body and controls the front and rear load.
Track rod assembly
Track rod is installed between knuckle and rear
sub frame and controls and compensates the
lateral load.

Stabilizer bar assembly
The stabilizer bar assembly is not activated if the
left/right wheels move up/down simultaneously, but if
both wheels move up/down differently it is activated
with frame to minimize the tilting of the body.
Coil spring
Coil spring is installed between
the coil spring link and body
frame. It relieves the vibrations
and impacts from wheels to
vehicle body.
Lower arm assembly
The lower arm is installed between knuckle and rear
sub frame and relieves the load to coil spring from
wheel. In other word, it controls the longitudinal load.

A. Indicators on instrument cluster
C. HECU assembly
The HECU assemblies for ABS and ESP have
similar appearance but they have different inner
structure and connector connections from each
other. D. Front brake assembly
The disc brake for 4WD vehicle is the same with
the one for 2WD vehicle.
7. BRAKE SYSTEM AND ESP SYSTEM LAYOUT
B. Master cylinder assembly
Description for master cylinder in this chapter is
based on ABS/ESP equipped vehicle. For CBS,
there is an extra pressure valve mounted to the
master cylinder.

H. Parking brake
M/T A/T
The parking brake is the mechanical device to
hold the vehicle. When pulling up the lever, the
parking brake cable between the lever and the
rear drum brake trailing shoe pulls the parking
brake lining to contact to drum.
E. Rear brake assembly
The disc brake for 4WD vehicle has the same
structure with the one for 2WD vehicle, but the
appearance and knuckle shape is different from
each other.

The wheel speed sensor for 4WD has the same
structure and mounting location with the one for
2WD vehicle. But the rear side wheel speed
sensor for 2WD vehicle has different sensor
appearance and mounting status because the
knuckle shape is different from the 4WD vehicle.

Steering gear box assembly
The steering gear box assembly consists of power cylinder and control valve. The power cylinder has a
cylinder, piston and piston rod. The control valve directs the oil to one end face of the piston to enhance
the steering force. There is a safety check valve which lets the driver steer manually when there is a
malfunction in the hydraulic circuit.
8. STEERING SYSTEM LAYOUT
1) HPS (Hydraulic Power Steering)
The hydraulic pump is a vane
type pump and consists of the
flow control valve and pressure
relief valve.The oil reservoir sends the oil to
the power steering pump and
receives the oil from the power
steering gear.There is a shock absorber which
is folded in the axial direction
when the vehicle is crashed and
a ignition switch assembly on
the column shaft.
The lower shaft minimizes the
torque change using a CV joint
which has constant angular
speed.

ECU
The ECU controls the electric
power steering system
depending on the driving
conditions, based on the
signals from the torque and
angle sensor.
2) EPS (Electric Power Steering)
Fuse
The vehicle with EPS has
EPS fuse (80A) mounted to
the positive (+) terminal of the
battery, and this fuse supplies
power to the EPS unit
directly..
Steering gear box assembly
When the driver turns the steering wheel, a torque is generated and the torque sensor and the steering
angle sensor in the EPS system detect the rotation of the steering column to run the electric motor. At
this time, the worm gear connected to the motor drives the helical gear mounted to the steering column
to generate the assist torque for the steering column. This allows the driver to operate the steering
wheel easier.

Colum shaft assembly
The column shaft assembly consists
of BLAC motor, ECU, torque and
angle sensors. The electric power
steering (EPS) system uses the
electric motor to assist the steering
force. It functions independently
regardless of whether the engine is
running or not, unlike the existing
hydraulic power steering.
The lower shafts functions in the
same way as the hydraulic type.

1. GUIDELINES FOR SERVICE WORKS
1) For Safety
To perform the service works easily ans safely, the service technicians must keep the proper working
procedures and rules.
This manual provides the useful instructions to the service technicians so that they can perform the
servive works with standard working process, skills, tips in time.
Please read this manual and follow the instructions carefully.
Signal words such as “WARNING”, “CAUTION” and “NOTE” have special meanings.
indicates information to assist maintenance and instructions.
However, above references and cautions cannot be inclusive measures, so should have habits of
paying attentions and cautions based on common senses.
indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury or property damage.
