Free Play Check ▶
Start the engine and place the wheels at
straight ahead direction.
Turn the steering wheel until the tires starts to
move and measure the distance on the
circumference of the steering wheel. A.
B.
Free play30mm
If the free play is out of the specified value,
check the free play in steering column shaft
connection and steering linkage. Replace or
repair if necessary.
Steering Effort Check ▶
Park the vehicle on a paved and flat ground and
place the front wheels at straight ahead direction.
Start the engine and let it run around 1,000 rpm.
Install the spring scale on the circumference of
the steering wheel and measure the steering
effort in both directions. A.

Place the front wheel on a turning radius
measuring tool.
Turn the steering wheel to the both ends and
measure the maximum steering angle. A.

Oil Level Check ▶
Check the fluid level on a level ground with the
engine turned off. The fluid level should be
between the MIN and MAX marks on the
reservoir cap gauge.
Place the vehicle on a level ground and start
the engine and let it run at idle speed.
Turn the steering wheel several times so that
the oil temperature reaches to normal
operating level (75~85˚C).
Place the steering wheel at straight ahead
direction.
Check the oil level in the power steering oil
reservoir. Adjust the oil level between MAX
and MIN. A.
B.
C.
D.
Oil Change ▶
If the difference between two measurements
is below 5 mm and the level is between MAX
and MIN level, it's normal. If it is over 5 mm,
bleed air from the system.
Open the power fluid reservoir cap and drain
the fluid completely with oil suction device.
To make it easy, turn the steering wheel to its
both ends several times.
Fill up the specified fluid into fluid reservoir
and bleed air from the steering system. A.

Air Bleeding ▶
The air bleeding should be done after servicing the
power steering system and when the difference
between two measurements (cooled and normal
temperature) is prominent.
Normal AbnormalLift up the vehicle very carefully.
Turn the steering wheel to its both ends
several times and add the oil up to MAX line
in the steering oil reservoir.
Periodically crank the starting motor and turn
the steering wheel to its both ends without
any interruption.
Check the oil level again. If the oil level is
fluctuated, repeat the procedures from step 3
to step 5.
Start the engine.
Turn the steering wheel to its both ends until
any bubble can be found in the steering oil
reservoir.
Perform the test drive and check the steering
wheel for normal operation and noise.
If the oil level abruptly goes up, bleed the air
from the system again. A.

If the air bleeding is not properly performed,
the life span of the power steering pump may
be shortened. -

Oil Pump Pressure Check ▶
Check the oil pump pressure to locate any defect
in oil pump.
Before checking the pressure, check the oil
level and belt tension. Prepare the empty
container to collect the spilled oil during the
service.
Unscrew the pressure line fitting in power
steering pump.
Install the pressure gauge between the
power steering pump and the power steering
oil pressure line.
Place the shift lever to neutral position. Apply
the parking brake.
Open the valve in pressure gauge. Start the
engine and let it run at idle speed.
Turn the steering wheel several times so that
the oil temperature reaches to normal
operating level. A.
B.
C.
D.
E.
Fully close the valve in pressure gauge and
measure the oil pressure. F.
To prevent internal damage, do not close the
gauge valve over 10 seconds.
Keep the oil temperature at proper range. -

fully open. G.
Pressure at no load3 ~ 5bar
If the pump pressure is in specified range, the
pump is normal. If not, replace the power
steering pump H.

During driving, the rotating tire repeats deformation and restoring movement in is tread. This
happens when the tire pressure is low in high speed driving.
However, when the wheel rotating speed is fast, the tire is deformed even before it is restored to
its original shape and the trembling wave appears on the tread portion. If this symptom lasts for
an extended period of time, the tire can be blown out in a short period of time.
If the standing wave symptom occurs on the tire, rubber on the tread comes off and eventually
the tire can be blown out which is very dangerous. When driving at high speed, the inflation
pressure should be increased to decrease heat generation due to extension and contraction
motion, to decrease hydroplaning and to prevent standing wave.
To prevent this symptom, it is recommended to increase the tire pressure 10 ~ 30 % higher than
the specified pressure value in high speed driving.
Specified tire inflation pressure35psi
2. ABNORMAL TIRE SYMPTOM

If weight is not equally distributed around the wheel, unbalance centrifugal force by the wheel
rotation produces vibration. As the centrifugal force is produced proportional to the square of the
rotating speed, the wheel weight should be balanced even at high speed. There are two types of
the tire and wheel balancing: static and dynamic. Abnormal vibration may also occur due to
unbalanced rigidity or size of tires.
1) Static Balance
When the free rotation of the wheel is
allowed, the heavier part is stopped on the
bottom if the wheel weight is unbalanced
and this is called "Static Unbalance". Also,
the state at which tire's stop position is not
same is called "Static Balance" when the
wheel is rotated again. If the part A is
heavier as shown in the figure 1, add the
balance weight of a weight corresponding
to unbalanced weight from B to A to
maintain the static balance. If the static
balance is not maintained, tramping, up
and down vibration of the wheels, occurs.
2) Dynamic Balance
The static unbalance of the wheel
creates the vibration in the vertical
direction, but the dynamic unbalance
creates the vibration in the lateral
direction. As shown in the figure 2 (a), if
two parts, (2) and (3), are heavier when
the wheels are under the static balance
condition, dynamic unbalance is
created, resulting in shimmy, left and
right vibration of the wheels, and the
torque Fxa is applied in the axial
direction. To correct the dynamic
unbalance, add the balance weight of a
same weight for two points of the
circumference of the rim, A and B, as
shown in the figure 2 (b), and apply the
torque in the opposite direction to the
torque Fxa to offset in order to ensure
smooth rotation of the wheel.
