InspectionINFOID:0000000012430497
CONDITION OF INSTALLATION
• Check installation conditions of steering gear, 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.
• Verify that the steering gear nuts are tightened to specification. Refer to ST-14, "
Exploded View".
STEERING WHEEL PLAY
1. Set the front wheels and tires in the straight-ahead position, start engine, then lightly turn steering wheel
to the left and right until the front wheels start to move. Measure steering wheel movement on the outer
circumference.
2. When the measurement value is outside the standard va lue, check backlash for each joint of steering col-
umn and installation condition of steering gear.
STEERING WHEEL NEUTRAL POSITION
Check steering wheel neutral position using the following procedure:
1. Confirm that front wheel alignment is correct. Refer to FSU-8, "
Adjustment".
2. Set the front wheels and tires in the straight-ahead posit ion, check if steering wheel is in the neutral posi-
tion.
3. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
4. If the neutral position cannot be attained by repositi oning the steering wheel two teeth or less on steering
stem, loosen the steering gear outer socket lock nuts, then adjust the inner sockets by the same amount
in the opposite direction.
5. Re-check the front wheel alignment. Refer to FSU-8, "
Adjustment".
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Tires need to be inflated normal pressure. Refer to WT-54, "
Tire Air Pressure".
3. Start engine.
4. Check steering wheel turning force using Tool when steering wheel has been turned 360 ° from the neutral position.
5. If steering wheel turning force is out of specification, inspect steering column. Refer to ST-10, "
Inspection".
6. If steering column meets specification, inspect steering gear. Refer to ST-14, "
Inspection".
FRONT WHEEL TURNING ANGLE
1. Perform toe-in inspection. Refer to FSU-8, "Adjustment".
CAUTION: Steering wheel axial end play : Refer to
ST-19, "
Steering Wheel
Axial End Play and Play".
Steering wheel play on the
outer circumference : Refer to
ST-19, "
Steering Wheel Axia l End Play and Play".
Tool number : — (J-44372)

Removal and InstallationINFOID:0000000012430500
REMOVAL
1. Set the front wheels and tires in the straight-ahead position.
2. Remove driver air bag module. Refer to SR-12, "
Removal and Installation".
3. Remove steering wheel lock nut.
4. Remove steering wheel using suitable tool. CAUTION:
Place a piece of tape across the spiral cable so it will not be rotated out of position.
5. Inspect steering wheel near the puller holes for damage. Replace as necessary.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Do not reuse steering wheel lock nut.
• Align spiral cable correctly before installing steering wheel . Make sure that the spiral cable is in the neutral
position. Refer to SR-16, "
Removal and Installation".
• Adjust the neutral position of the steering angle sensor. Refer to BRC-55, "
ADJUSTMENT OF STEERING
ANGLE SENSOR NEUTRAL POSITION : Description".
CAUTION:
• The spiral cable may snap due to steering operation if the cable is not installed in the correct posi-
tion.
• With the steering linkag e disconnected, the cable may snap by turning the steering wheel beyond
the limited number of turns.

• Before installation, check that steering column tilt is in the middle position.
• For intermediate shaft bolt, and lower joint bolt direction, refer to ST-12, "
Exploded View".
• To install align the steering gear guide protrusion (A) with the
groove of lower joint (1), make sure the bolt is securely seated in
groove (B) of steering gear before final tightening.
CAUTION:
If a guide protrusion is not included, align with the matching
mark placed at the removal step.
• When tightening lower joint bolt to the steering gear lower shaft,
temporarily tighten it and make sure there is no sticking or galling
before final tightening.
• When connecting intermediate shaft upper side (1) and column shaft, make sure the bolt is securely seated in groove (A) of col-
umn shaft before final tightening.
• Perform inspection after installation. Refer to ST-13, "
Inspection".
InspectionINFOID:0000000012430506
INSPECTION AFTER REMOVAL
• Check each part of steering intermediate shaft, lowe r joint, and steering column for damage or other mal-
functions. Replace if there are any abnormal conditions.
INSPECTION AFTER INSTALLATION
• Rotate steering wheel to make sure it is centered and there is no binding, noise or excessive steering effort.
• Make sure that the number of turns are the same from the straight-ahead position to the left and right locks.
• Check each part of steering intermediate shaft, lowe r joint, and steering column for damage or other mal-
functions. Replace if there are any abnormal conditions.
• Check the steering wheel play, neutral position steeri ng wheel, steering wheel turning force, and front wheel
turning angle. Refer to ST-5, "
Inspection".
• Check the neutral position of the steering angle sensor. Refer to BRC-55, "
