REMOVAL AND INSTALLATION

STEERING WHEEL

On-Vehicle Inspection and Service

INFOID:0000000009883505

CHECKING CONDITION OF INSTALLATION

• Check installation condition of power 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 if the nuts for power steering gear assembly are loose.

Refer to 

ST-15

.

CHECKING STEERING WHEEL PLAY

1. Turn tires straight ahead, start engine, then turn steering wheel to the left and right lightly, and measure

steering wheel movement on the outer circumference when steering wheel is turned up to the point where

tires start moving.

CHECKING NEUTRAL POSITION ON STEERING WHEEL

• Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to 

FSU-

5, "Front Wheel Alignment"

.

1. Turn tires straight ahead, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositioning the steering wheel two teeth or less on steering

stem, loosen tie-rod lock nuts of steering outer sockets, then adjust tie-rods by the same amount in the

opposite direction.

CHECKING 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 operating temperature of 60

°– 80°C (140°– 176°F).

4. Tires need to be inflated to specified pressure. Refer to 

WT-53, "Tire"

.

5. Check steering wheel turning force using Tool when steering

wheel has been turned 360

° from the neutral position.

6. If steering wheel turning force is out of specification, inspect

steering column. Refer to 

ST-17, "Removal and Installation"

.

POWER STEERING OIL PUMP

POWER STEERING OIL PUMP

On-Vehicle Inspection and Service

INFOID:0000000009883506

CHECKING RELIEF OIL PRESSURE

CAUTION:

Before starting work, confirm belt tension is proper.
1. Connect Tool between power steering oil pump discharge con-

nector and high pressure hose and then bleed air from the

hydraulic circuit.

2. Start engine. Allow engine to run until tank temperature reaches 50

°– 80°C (122°– 176°F).

CAUTION:

• Warm up engine with shut-off valve fully opened. If engine is started with shut-off valve closed,

fluid pressure in power steering oil pump increases to maximum. This will raise power steering

fluid temperature excessively.

• Be careful not to contact hose with belt when engine is started.

3. With engine at idle, close shut-off valve and read the relief oil pressure.

CAUTION:

Do not close shut-off valve of pressure gauge for more than 10 seconds.

4. After measurement, open shut-off valve slowly.

• If relief oil pressure is outside the specification, disassemble and repair power steering oil pump. Refer

to 

ST-24, "Disassembly and Assembly"

.

5. After inspection, disconnect oil pressure gauge and oil pressure gauge adapter from hydraulic circuit, con-

nect power steering oil pump discharge connector and high pressure hose and copper sealing washers.

Add power steering fluid and bleed air from hydraulic circuit thoroughly. Refer to 

ST-6, "Air Bleeding

Hydraulic System"

.

CAUTION:

DO not reuse copper sealing washers.
