1. Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
Do not allow the fluid level to drop below the MIN line.
2. Start engine and hold steering wheel at each lock position for three seconds at idle to check for fluid leak-
age.
3. Repeat step 2 above several times at approximately three 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 or white contamination.
5. Stop engine if bubbles or white contamination is present. Perform step 2 and 3 above after waiting until
bubbles or white contamination disappear.
6. Stop the engine, and then check fluid level.

STEERING WHEEL
STEERING WHEEL
Inspection
INFOID:0000000009465771
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
.
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-6, "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 50 - 80
°C (122 - 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 degrees from the neutral position.
5. If steering wheel turning force is out of specification, check rack sliding force.

a. While pulling outer socket slowly in
±11.5 mm (±0.453 in) range
from neutral position, make sure rack sliding force is within
specification using Tool.
b. If rack sliding force is not within specification, replace steering
gear assembly.
6. If rack sliding force is OK, inspect steering column. Refer to
23, "Removal and Installation"
FRONT WHEEL TURNING ANGLE
• 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.
• Measure rack stroke in neutral position if angles are outside the
specified value.

POWER STEERING OIL PUMP
POWER STEERING OIL PUMP
Inspection
INFOID:0000000009465772
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 the shut-off valve fully. Refer to
2. Start engine. Run engine until power steering fluid temperature
reaches 50 - 80
°C (122 - 176°F).
CAUTION:
• Leave the shut-off valve of the Tool fully open while start-
ing and running engine. If engine is started with the shut-
off valve closed, the hydraulic pressure in oil pump goes
up to the relief pressure along with unusual increase of
power steering fluid temperature.
• Be sure to keep hose clear of belts and other parts when
engine is started.
3. Fully close the shut-off valve with engine at idle and measure
the relief oil pressure.
CAUTION:
Do not keep shut-off valve closed for 10 seconds or longer.
4. Open the shut-off valve slowly after measuring. Replace oil pump if the relief oil pressure is outside the
standard.
5. After inspection, disconnect the Tool from hydraulic circuit, then add power steering fluid and perform air
bleeding. Refer to
Tool numbers
: KV48103500 (J-26357)
: KV48102500 (J-33914)
Relief oil pressure : Refer to
SGIA0915E
