POWER STEERING FLUID
InspectionINFOID:0000000003826225
FLUID LEVEL
1. Check fluid level with engine stopped.
2. Ensure that fluid level is between MIN and MAX.
3. Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
 The fluid level should not exceed the MAX line. Excessive fluid causes fluid leakage from the
cap.
 Never reuse drained power steering fluid.
FLUID LEAKAGE
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run the engine until the fluid temperature reaches 50 to 80°C
(122 to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully check for fluid leakage.
CAUTION:
Never hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that power steer-
ing oil pump assembly may be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to ST-32, "
Inspection".
6. Check steering gear boots for accumulation of fluid leaked from steering gear.
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, the following symptoms can be observed.
 Bubbles are created in reservoir tank.
 Clicking noise can be heard from oil pump.
 Excessive buzzing in the oil pump.
NOTE:
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:
Fill reservoir tank with a sufficient amount of fluid so that fluid level is not below the MIN line while
turning steering wheel.
2. Start the engine and hold steering wheel at each lock position for 3 second at idle to check for fluid leak-
age.HOT (A) : Fluid temperature 50 – 80°C (122 – 176°F)
COLD (B) : Fluid temperature 0 – 30°C (32 – 86°F)
Recommended fluid : Refer to MA-11, "
Fluids
and Lubricants".
Fluid capacity : Refer to ST-37, "
General
Specifications".

3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Never 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 white contamination.
5. Stop the 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.

STEERING WHEEL
5. Check steering wheel turning force when steering wheel has
been turned 540° from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
6. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump. Regarding relief hydraulic pressure of oil
pump, refer to ST-32, "
Inspection".
RACK SLIDING FORCE
1. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to ST-16, "Exploded
View".
2. Start and run the engine at idle to make sure steering fluid has reached normal operating temperature.
3. While pulling outer socket slowly in ±11.5 mm (±0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
4. If rack sliding force is not within specification, overhaul steering
gear assembly.
FRONT WHEEL TURNING ANGLE
1. Check front wheel turning angle after toe-in inspection. Refer to FSU-7, "Wheel Alignment Inspection".
2. Place front wheels on turning radius gauges and rear wheels on
stands, so that vehicle can be level.
3. Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
4. With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.Standard

REMOVAL
1. Set the vehicle to the straight-ahead position.
2. Remove front tires.
3. Remove splash guards (RH and LH). Refer to EXT-22, "
FENDER PROTECTOR : Exploded View".
4. Remove engine under cover. Refer to EXT-28, "
Exploded View".
5. Remove heat insulator from front floor.
6. Remove cotter pin (1), and then loosen the nuts.
7. Remove steering outer socket (2) from steering knuckle (3) so
as not to damage ball joint boot (4) using suitable ball joint
remover.
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover from suddenly coming
off.
8. Remove high pressure piping and low pressure hose of hydrau-
lic piping, and then drain power steering fluid.
9. Remove steering hydraulic piping bracket from front steering
gear assembly.
10. Remove power steering solenoid valve harness connector and harness clip.
11. Separate the lower shaft from the steering gear assembly by sliding the slide shaft.
CAUTION:
Spiral cable may be cut if steering wheel turns while separating steering column assembly and
steering gear assembly. Be sure to secure steering wheel using string to avoid turning.
12. Remove the front stabilizer assembly. Refer to FSU-16, "
Exploded View".
13. Remove the mounting bolts and nuts of steering gear assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:

RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the oil pressure gauge (SST: KV48103500) and the oil
pressure gauge adapter (SST: KV48102500) between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer to ST-7,
"Inspection".
2. Start the engine. Run the engine until oil temperature reaches
50 to 80°C (122 to 176°F).
CAUTION:
 Leave the valve of the oil pressure gauge fully open while
starting and running the 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 oil pressure gauge 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. Repair oil pump if the relief oil pressure is outside the standard.
Refer to ST-29, "
Disassembly and Assembly".
5. Disconnect the oil pressure gauge from hydraulic circuit.
6. When installing eye bolt (1) and copper washers (2) to oil pump
(3), refer to the figure.
CAUTION:
 Never reuse copper washer.
 Apply power steering fluid or equivalent to around copper
washer, then install eye bolt.
 Install eye bolt with eye joint (assembled to high pressure
hose) (B) protrusion (A) facing with pump side cutout, and
then tighten it to the specified torque after tightening by
hand. Refer to ST-34, "
Exploded View".
 Securely insert harness connector to pressure sensor.
