Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of the

system.

1. Turn steering wheel several times from full left stop to full right stop with engine off.

CAUTION:

Turn steering wheel while filling reservoir tank with fluid so as not to lower fluid level below the

MIN line.

2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.

CAUTION:

Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-

bility that oil pump may be damaged.)

4. Check fluid for bubbles and while contamination.
5. Stop engine if bubbles and white contamination do not drain out. Perform step 2 and 3 above after waiting

until bubbles and white contamination drain out.

6. Stop the engine, and then check fluid level.

INSTALLATION CONDITION

• Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-

umn assembly.

• Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial

direction.

• Check steering gear assembly bolts and nut for looseness. Refer to 

ST-17, "Exploded View"

.

STEERING WHEEL PLAY

• Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn

steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on the

outer circumference.

• When the measurement value is outside the standard value, check backlash for each joint of steering col-

umn assembly and installation condition of steering gear assembly.

NEUTRAL POSITION OF STEERING WHEEL

• Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the

correct position.

• Perform neutral position inspection after wheel alignment. Refer to 

FSU-7, "Inspection and Adjustment"

.

• Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

• Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steer-

ing wheel is not in the neutral position.

STEERING WHEEL TURNING FORCE

1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. Make sure the fluid temperature is

approximately 60

° to 80°C (140° to 176°F).

Tires need to be inflated to normal pressure.

4. Check steering wheel turning force using tool when steering

wheel has been turned 360

° from the neutral position.

5. If steering wheel turning force is out of specification, check rack

sliding force. Refer to 

ST-28, "Inspection"

.

6. If rack sliding force is not within specifications, adjust rack slid-

ing force. Refer to 

ST-28, "Inspection"

.

7. If rack sliding force is OK, inspect steering column. Refer to 

ST-14, "Removal and Installation"

.

• Check front wheel turning angle after toe-in inspection. Place front

wheels on turning radius gauges and rear wheels on stands.

Check the maximum inner and outer wheel turning angles for LH

and RH road wheels.

• With the engine at idle, turn steering wheel from full left stop to full

right stop and measure the turning angles.

Unit: Degree minute (Decimal Degree)

• Measure rack stroke if angles are outside the specified value.

POWER STEERING OIL PUMP

POWER STEERING OIL PUMP

Inspection

INFOID:0000000004204017

RELIEF OIL PRESSURE

CAUTION:

Make sure that belt tension is normal before starting the following procedure.
1. Connect the Tool between oil pump discharge connector and

high-pressure hose. Bleed air from the hydraulic circuit while

opening valve fully. Refer to 

ST-8, "Inspection"

.

2. Start engine. Run engine until oil temperature reaches 50

° to

80

°C (122° to 176°F).

CAUTION:

• Leave the valve of the hydraulic pressure gauge [SST]

fully open while starting and running engine. If engine is

started with the valve closed, the hydraulic pressure in oil

pump goes up to the relief pressure along with unusual

increase of oil temperature.

• Be sure to keep hose clear of belts and other parts when

engine is started.

3. Fully close the Tool valve with engine at idle and measure the

relief oil pressure.

CAUTION:

Never keep valve closed for 10 seconds or longer.

4. Open the valve slowly after measuring. Replace oil pump is the relief oil pressure is outside the standard.
5. After inspection, disconnect the Tool from hydraulic circuit, then add fluid and bleed air. Refer to 

ST-8,

"Inspection"

.
