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 play30 mm
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.
B.
C.
Steering effort in
standstillbelow 3.0 kg
The difference between both sides should
be within 0.6 kg.
Steering Angle Check ▶
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.
B.
Steering
angleInner36.4°
Outer31.5°
If the steering angle is out of the specified
value, check and adjust the toe-in.

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.

H.
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. -
-
Relief pressure93.3 ~ 100.4 kgf/cm²

11-12
Measure the oil pressure with the gauge
valve fully open. G.
Pressure at no load3 ~ 5 bar
If the pump pressure is in specified range,
the pump is normal. If not, replace the power
steering pump H.
Turn the steering wheel right or left until it
stops with the engine idling and valve fully
open. I.
Oil pressure78 ~ 83 bar

1. OVERVIEW
The power steering has been designed to make the wheel move more easily than in a manual steering
system. The hydraulic power assists the process utilizing hydraulic fluid. The fluid increases pressure
in the power steering pump and aids the movement of the steering mechanism. The power steering
system consists of pump, oil reservoir, rack and gear box. The power steering pump is a vane type
and delivers hydraulic pressure to operate the power steering system. The pressure relief valve in the
pump controls the discharging pressure. The rotary valve in the rack and the pinion gear directs the oil
from the power steering pump to one side of the rack piston. The integrated rack piston converts the
hydraulic pressure to linear movement. The operating force of the rack moves the wheels through the
tie rod, the tie rod end and the steering knuckle. Even though the hydraulic pressure cannot be
generated, a driver can steer the vehicle without power assist but it needs very high steering force. In
this case, the operating force of the steering wheel is conveyed to the pinion, and the movement of the
pinion moves the rack through the pinion gear combined to the rack gear.
