POWER STEERING FLUID INSPECTIONA6E661432040201Fluid Level Inspection
1. Inspect the power steering fluid level.
•Add fluid to the specified level as necessary.
Fluid specification
ATF M-III or equivalent (e.g. Dexron
®II)
Fluid Leakage Inspection
Caution
•If the steering wheel is kept in the fully turned position for more than 5 seconds, the fluid
temperature will rise excessively and adversely affect the oil pump.
1. Start the engine and let it idle.
2. Turn the steering wheel fully to the left and right to apply fluid pressure.
Note
•The points where fluid leakage may occur are indicated in the figure.
3. Inspect for fluid leakage.
•If fluid leakage is found, replace the related pipe or hose.

Fluid Pressure Inspection
1. Assemble the SSTs as shown in the figure.
2. Disconnect the pressure pipe from the oil pump,
and connect the SSTs.
Tightening torque
29.4—44.1 N·m {3.0—4.4 kgf·m, 22—32 ft·lbf}
3. Bleed the air from the system.
4. Open the gauge valve fully.
5. Start the engine and turn the steering wheel fully
left and right to raise the fluid temperature to 50—
60 °C {122—140 °F}.
6. Close the gauge valve completely.
7. Increase the engine speed to 1,000—1,500 rpm
and measure the fluid pressure generated by the
oil pump.
•If the pressure is not within the specification,
repair or replace the oil pump component.
Caution
•If the valve is left closed for more than 5
seconds, the fluid temperature will rise
excessively and adversely affect the oil
pump.

engine speed to 1,000—1,500 rpm.
9. Turn the steering wheel fully to the left and right,
then measure the fluid pressure generated at the
gear housing.
•If the pressure is not within the specification,
repair or replace the steering gear
component.
Caution

STEERING GEAR AND LINKAGE (MZR-CD (RF TURBO)) REMOVAL/INSTALLATIONA6E661432960201
Caution
•Performing the following procedures without first removing the ABS wheel-speed sensor may
possibly cause an open circuit in the harness if it is pulled by mistake. Before performing the
following procedures, remove the ABS wheel-speed sensor (axle side) and fix it to an appropriate
place where the sensor will not be pulled by mistake while servicing the vehicle.
L.H.D.
1. Remove the under cover and mud guard. (Left side)
2. Remove the front auto leveling sensor.
3. Separate the stabilizer control link. (shock absorber side)
4. Separate the front lower arm (front and rear) ball joint.
5. Remove the shock absorber bolt. (lower side)
6. Remove in the order indicated in the table.
7. Install in the reverse order of removal.
8. Inspect the toe-in.
9. Adjust the headlight zeroset.
