Noise Hissing Noise in Steering Gear
There is some noise with all power steering systems. One of the most common is a hissing
sound when the steering wheel is turned and the car is not moving. This noise will be most
evident when turning the wheel while the brakes are being applied. There is no relationship
between this noise and steering performance. Do not replace the valve unless the "hissing"
noise becomes extreme. A replaced valve will also make a slight noise, and is not always a
solution for the condition.
Rattling or chucking
noise in the rack and
pinion Interference with hoses from vehicle body

SERVICE ADJUSTMENT PROCEDURE
CHECKING STEERING WHEEL FREE PLAY
1. Start the engine and with the steering wheel in the straight ahead position.
2. Measure the play while turning the steering wheel to the left and right.
Standard value :
Steering wheel free play : 30 mm (1.1 in)
3.If the play exceeds the standard value, inspect the connection between the steering shaft and tie rod ends.
CHECKING STEERING ANGLE
1.Place the front wheel on a turning radius gauge and measure the steering angle.
Standard value
VRS on Inner
38.64 °
Outer 31.78 °
VRS off Inner
41.91 °
Outer 33.54 °
2. If the measured value is not within the standard value, adjust the toe and inspect again.
CHECKING THE TIE ROD END BALL JOINT STARTING TORQUE
1.Disconnect tie rod and knuckle with the special tool (09568- 4A000).

2.Shake the ball joint stud several times to check for looseness.
Tie rod end ball joint starting torque :
30 kg·cm or less
3.If the starting torque exceeds the upper limit of the standard value, replace the tie rod end.
4. Even if the starting torque is below the lower limit of the standard value, check the play of the ball joint and replace
if necessary.
CHECKING STEERING WHEEL RETURN
1.The force required to turn the steering wheel and the wheel return should be the same for both moderate and sharp
turns.
2. When the steering wheel is turned 90° and held for a couple of seconds while the vehicle is being driven at 20- 30
kph (12- 19 mph), the steering wheel should return at least 20° from its central position when it is released.
If the steering wheel is turned very quickly, steering may be momentarily difficult. This is not a malfunction
because the oil pump output will be somewhat decreased.

CHECKING POWER STEERING BELT TENSION
Refer to EM group(Timing system).
CHECKING POWER STEERING FLUID LEVEL
1.Position the vehicle on a level surface.
2. Start the engine. With the vehicle kept stationary, turn the steering wheel several times continuously to raise the
fluid temperature to 50- 60°C (122 - 140°F).
3. With the engine at idle, turn the steering wheel fully clockwise and counter- clockwise several times.
4. Make sure that there is no foaming or cloudiness in the reservoir fluid.
5. Stop the engine and check for any difference in fluid level between a stationary and a running engine.
a.If the fluid level varies 5 mm (0.2 in) or more, bleed the system again.
b. If the fluid level suddenly rises after stopping the engine, further bleeding is required.
c. Incomplete bleeding will produce a chattering sound in the pump and noise in the flow control valve, and
lead to decreased durability of the pump.
REPLACING POWER STEERING FLUID
1.Jack up the front wheels and support them with jackstands.
2. Disconnect the return hose from the oil reservoir and plug the oil reservoir.
3. Connect a vinyl hose to the disconnected return hose, and drain the oil into a container.
4. Remove the fuel pump fuse, then start the engine and wait for the engine to stall. Next, while operating the starting
motor intermittently, turn the steering wheel all the way to the left and then to the right several times to drain the
fluid.
5. Connect the return hoses, then fill the oil reservoir with the specified fluid.
6. Reinstall the fuel pump fuse.
7. Start the engine. Check for oil leakage.
8. Stop the engine.
9. Bleed the system.
Power steering fluid type : PSF - 3
Total quantity : Approx 1.1 liter
AIR BLEEDING
1.Remove the fuel pump fuse, then start the engine and wait for the engine to stall. Next, while operating the starting
motor intermittently (for 15 ~ 20 seconds), turn the steering wheel all the way to the left and then to the right five or
six times.
