CHECKING CONDITION OF INSTALLATION
• Check installation condition of steering gear assembly, front suspension, axle and steering column.
• Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
• Check if the nuts for steering gear assembly are loose. Refer to ST-23, "
Removal and Installation".
CHECKING STEERING WHEEL PLAY
1. Turn tires straight ahead, start engine, then turn steer ing 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-
6, "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, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositi oning the steering wheel two teeth or less on steering
stem, loosen tie-rod lock nuts of steering outer socket s, 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-52, "
Tire".
5. Check steering wheel turning force using Tool when steering wheel has been turned 360 ° from the neutral position.

POWER STEERING GEAR AND LINKAGE
7. Remove steering outer socket from steering knuckle using Tool.Be careful not to damage ball joint boot.
CAUTION:
Temporarily tighten nut to prevent damage to threads and
to prevent Tool from coming off.
8. Remove oil piping (high pressure side and low pressure side) from steering gear assembly, then drain fluid from piping.
9. Remove lower joint bolt of lower joint shaft.
10. Remove nuts of steering gear assembly using power tool, then remove bolts and steering gear assembly.
INSTALLATION
Installation is in the reverse order of removal.
• After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6, "
Front
Wheel Alignment".
• After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-8, "
ADJUST-
MENT OF STEERING ANGLE SENSOR NEUTRAL POSITION : Special Repair Requirement".
