Gear Preload Check ▶
Preload is the term used in mechanical engineering to describe the load applied to a fastener
merely as a result of being fastened (and before any external loads are applied)
4. INSPECTION AND MAINTENANCE
Place the wheels at straight ahead
direction.
Lift up the vehicle with a lift.
Unscrew the adjusting plug lock nut.
Measure the torque of the adjusting plug. 1.
2.
3.
4.
If the torque is excessive or too low, adjust
to the specified torque. 5.
Place the rack gear to the center
position.
Tighten the adjusting plug to 10.2 Nm.
Turn the pinion gear so that the rack
gear is turned to lock to lock 5 times.
Unscrew the adjusting plug.
Tighten the adjusting plug to 4.6 to 5.6
Nm.
Unscrew the adjusting plug to 67.5°. -

The difference between both sides should
be within 0.6 kg.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. 1.
2.
3. Steering Effort Check ▶
Steering Angle Check ▶
Place the front wheel on a turning radius
measuring tool.
Turn the steering wheel to the its both
ends and measure the maximum steering
angle. 1.
2.
If the steering angle is out of the specified
value, check and adjust the toe-in.
Steering angleInner37.59˚
Outer33.48˚
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. 1.
2.
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.
Free play30 mm
Steering effort in
standstillbelow 3.0 kg

Oil Change ▶
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. 1.
2. Oil Level Check ▶
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. 1.
2.
3.
4.
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. 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.

Air Bleeding ▶
Lift 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. 1.
2.
3.
4.
5.
6.
7.
8.
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.
Max
Min
Normal Abnormal
If the air bleeding is not properly
performed, the life span of the power
steering pump may be shortened. -

Oil Pump Pressure Check ▶
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. 1.
2.
3.
4.
5.
Before checking the pressure, check the oil
level and belt tension. Prepare the empty
container to collect the spilled oil during the
service. Check the oil pump pressure to locate any
defect in oil pump.
Fully close the valve in pressure gauge and
measure the oil pressure. 6.
Relief pressure
90 ± 3 bar

Steering gear box
To prevent internal damage, do not close
the gauge valve over 10 seconds.
Keep the oil temperature at proper range. -

Measure the oil pressure with the gauge
valve fully open. 7.
Pressure at no load
3 to 5 bar
If the pump pressure is in specified range,
the pump is normal. If not, replace the
power steering pump 8.
Turn the steering wheel righ or left until it
stops with the engine idling ans valve fully
open. 9.
Oil pressure78 to 83 bar
To prevent the internal damage, do not
close the gauge valve for over 10
seconds.
Keep the oil temperature at proper range. -
