SERVICE ADJUSTMENT PROCEDURE
CHECKING STEERING WHEEL FREE PLAY
  1. Start the engine with the steering wheel in the straight ahead position, apply a force of 5 N (1.1 lb) to the steering wheel in the peripheral direction.

  1. Measure the play at the circumference of the steering wheel.

    MEASUREMENT SPECIFICATION
    Steering wheel free play 0-30 mm ( 0-1.1 in )
  1. If the play exceeds the standard value, inspect the contact of 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.

    Wheel angle [Standard value]:
    Inner wheel
    3537, 130'
    Outer wheel
    3076'
  1. If the measured value is not within the standard value, adjust the linkage.

CHECKING TIE ROD END BALL JOINT STARTING TORQUE
  1. Mount two nuts on the ball joint, and then measure the starting torque.

SPECIFICATION
Tie rod end ball joint starting torque..... 0.5-2.5 Nm (5-25 kg.cm, 4-22 lb.ft)
  1. If the starting torque exceeds the upper limit of standard value, replace the tie rod end.

    NOTE
    Even if the starting torque is below the lower limit of the standard value, the ball joint may be reused unless it has drag and excessive play.
CHECKING STATIONARY STEERING EFFORT
  1. Place the vehicle on a level surface and place the steering wheel in the straight ahead position.

  1. Increase the engine speed to 1000 100 rpm.

    NOTE
    After checking, reset the engine speed to the standard value (idling speed).
  1. Measure the turning force with a spring scale by turning the steering wheel clockwise and counterclockwise one and a quarter turns.

    SPECIFICATION
    Stationary steering effort [Standard value]..... 33.3 N (3.4 kg,15.1 lbs) or less
  1. Check that there is no excessive force change while turning the steering wheel.

  1. If the stationary steering effort is excessive, check and adjust the following points.

    1. Damage or cracks of the dust covers of the lower arm ball joint and tie rod end.
    1. Pinion preload of the steering gear box and turning starting torque of the tie rod end ball joint.
    1. Turning starting torque of the lower arm ball joint.
CHECKING STEERING CHARACTERISTICS

Drive the vehicle at 0-80 km/h and check the following items.

  1. Turn the steering wheel at 0-80 km/h and hold for 1-2 seconds then release it.

  1. Steering wheel should be free from abnormal vibration.

  1. Steering system should be free from squealing or hissing noise from gear box, pump or drive belt.

  1. Steering operation should be smooth and free from catch.

CHECKING POWER STEERING FLUID LEVEL
  1. Position the vehicle on a level surface.

  1. Start the engine. With the vehicle kept stationary, turn the steering wheel several times continuously to raise the fluid temperature from 50 to 60C (122 to 140F).

  1. With the engine at idle, turn the steering wheel fully clockwise and counterclockwise several times.

  1. Make sure there is no foaming or cloudiness in the reservoir fluid.

  1. Stop the engine to check for a difference in fluid level between a stationary and a running engine.

    NOTE
    1. If the fluid level varies 5 mm (0.2 in.) or more, bleed the system again.
    2. If the fluid level suddenly rises after stopping the engine, insufficient bleeding is indicated.
    3. Incomplete bleeding will produce a chattering sound in the pump and a noise in the flow control valve, decreasing durability of the pump.
REPLACING POWER STEERING FLUID
  1. Jack up the front of the car and support with rigid racks.

  1. Disconnect the return hose from the oil reservoir and plug the oil reservoir.

  1. Connect a hose to the disconnected return hose, and drain the oil into a container.

  1. Disconnect the high-tension cable at the ignition coil side.

    While operating the starter motor intermittently, turn the steering wheel all the way to the left and then to the right several times to drain the fluid.

  1. Connect the return hoses, then fill the oil reservoir up to the "MAX" level with the specified fluid.

    Power steering fluid: AFT DEXRONII type or TEXAMATIC DEXRONII

    Total quantity: Approx. 0.9 liter (0.95 qts)

  1. Bleed the system.

AIR BLEEDING
  1. Fill the power steering fluid reservoir up to the "MAX" position with specified fluid.

  1. Jack up the front wheels.

  1. Disconnect the ignition coil high tension cable, and then, while operating the starter motor intermittently (for 15 to 20 seconds), turn the steering wheel all the way to the left and then to the right five or six times.

    NOTE
    1. During air bleeding, replenish the fluid supply so that the level does not fall below the lower position of the filter.
    2. If air bleeding is done while the vehicle is idling, the air will be broken up and absorbed into the fluid. Be sure to do the bleeding only while cranking.
  1. Connect the high tension cable, and then start the engine (idling).

  1. Turn the steering wheel to the left and then to the right, until there are no air bubbles in the oil reservoir.

    NOTE
    Do not hold the steering wheel turned all the way to either stop for longer than ten seconds.
  1. Confirm that the fluid is not milky, and that the level is up between "MAX" and "MIN" marks on the reservoir.

  1. Check that there is little change in the fluid level when the steering wheel is turned left and right.

    NOTE
    1. If fluid level changes up and down considerably when the steering wheel is turned or fluid overflows from the reservoir and the engine is stopped, air bleeding is not enough. Air bleeding should be done gain.
    2. If air bleeding is not enough, moan noise from the pump becomes more strident and air in the system will shorten the life of the pump and other parts.
CHECKING POWER STEERING BELT TENSION
  1. Depress the V-belt by applying a pressure of 98 N (10 kgf, 22 lb) at the specified point, and measure the deflection to confirm that it is within the standard value.

    SPECIFICATION
    V-belt deflection..... 6-9 mm (0.24-0.35 in)
  1. To adjust the belt tension, loosen the oil pump mounting bolts, move the oil pump, and then retighten the bolts.

OIL PUMP PRESSURE TEST
  1. Disconnect the pressure hose from the oil pump. Connect the special tool between the oil pump and pressure hose as illustrated.

  1. Bleed the air, and then star the engine and turn the steering wheel several times so that the fluid temperature rises to approximately 50C (122F).

  1. Increase the engine speed to 1,000 rpm.

  1. Close the shut-off valve of the special tool and measure the fluid pressure to confirm that it is within the standard value range.

    Oil pump relief pressure [Standard value]..... 6.1-6.6 MPa (62-67 kg/cm2, 882-953 psi)

    CAUTION
    Do not keep the shut-off valve on the pressure gauge closed for no more than ten seconds.
  1. Remove the special tools, and tighten the pressure hose to the specified torque.

SPECIFICATION
Pressure hose..... 55-65 Nm (550-650 kg.cm, 40.6-47.9 lb.ft)
