STEERING WHEEL

STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceEGS001BY
CHECKING CONDITION OF INSTALLATION

Check installation conditions of steering gear assembly, front suspension, axle and steering column.

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 mounting bolts and nut for looseness. Refer to PS-16, "COMPONENT" .
CHECKING 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 and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL

Make sure that steering gear assembly, steering column and steering wheel are installed in the correct
position.

Perform neutral position inspection after wheel alignment. Refer to FSU-6, "Wheel Alignment" .

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
steering wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is
approximately 50 to 80°C (122 to 176°F).]
4. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position.
NOTE:

Multiply the distance (L) from the hook of spring scale to the
center of steering wheel by the measurement value with a
spring scale.

Perform the following manner when the guideline value is
hard to be measured.
a. Park vehicle on a level and dry surface, set parking brake.
b. Remove driver air bag module. Refer to SRS-30, "
DRIVER AIR BAG MODULE" .
c. Start engine at idle, then check steering wheel turning force with
pre-load gauge [SST].
5. 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 PS-27,
"OIL PUMP PULLEY HYDRAULIC PRESSURE INSPECTION" .
a. Disconnect lower shaft and steering knuckle from steering gear
assembly. Refer to FAX-7, "
Removal and Installation" , PS-11,
"COMPONENT" . Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Steering wheel
turning force: 36 N (3.7 kg, 8.2 lb) or less

OIL PUMP PULLEY HYDRAULIC PRESSURE INSPECTION
Before starting following procedure, check tension of belt.
1. Raise vehicle. Connect oil pressure gauge between oil pump
discharge connector and high pressure hose. Then bleed the
hydraulic circuit.
2. Start engine. Run engine until oil temperature reaches 50°C -
80°C (122 - 176°F).
CAUTION:

Leave valve of hydraulic pressure gauge fully open while
starting and running engine. If engine is started with
valve closed, hydraulic pressure in oil pump goes up.
This will relief pressure along with abnormal increase of
oil temperature.

Care must be taken to keep hose clear of belt and other parts when engine is started.
3. Fully close hydraulic pressure gauge valve with engine at idle. Measure relief pressure.
4. After measurement, open valve slowly.
CAUTION:
Never keep valve closed for 10 seconds or longer.

If relief pressure is outside specification, disassemble and service oil pump. Refer to PS-28, "Disas-
sembly and Assembly(QR20DE and QR25DE Engine Models)" , PS-33, "Disassembly and Assembly
(YD22DDTi Engine Model)" .
5. After inspection, remove oil pressure gauge from hydraulic circuit. Add fluid. Be sure to bleed the system
completely. Refer to PS-6, "
Air Bleeding Hydraulic System" .
Removal and Installation (QR20DE and QR25DE Engine Models)EGS000AG
REMOVAL
1. Loosen adjusting screw and oil pump mounting bolt. Then, remove belt.
2. Remove union bolt and hose for oil pump.
3. Remove oil pump bracket attaching bolt.
4. Remove oil pump from vehicle.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.

After installation, adjust belt tension. Refer to EM-13, "DRIVE BELTS" .

After installation, be sure to bleed system. Refer to PS-6, "Air Bleeding Hydraulic System" . Relief oil pressure
