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 val ue, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
• Make sure that steering gear assembly, steering colu mn assembly and steering wheel are installed in the
correct position.
• Perform neutral position inspection after wheel alignment. Refer to PS-2, " Precaution for Supplemental
Restraint System (SRS) "AIR BA
G" and "SEAT BELT PRE-TENSIONER" " .
• Set vehicle to the straight-ahead position and c onfirm 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 steer-
ing 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. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position using suitable tool as
shown.
4. If steering wheel turning force is out of the specification, refer to STC-6, " How to Perform Trouble Diagnosis " .
CHECKING FRONT WHEEL TURNING ANGLE Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Steering wheel
turning force : Less than 36 N (3.7 kg-f, 8.2 lb-f)

• Check front wheel turning angle after toe-in inspection. Place front
wheels on turning radius gauges and rear wheels on stands.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
• With the engine at idle, turn steering wheel from full left stop to full right stop and measure the turning angles.
• Measure rack stroke if angles are outside the specified value.
• Disassemble steering gear assembly to check the cause that rack stroke is outside of the standard.
• Steering angles are not adjustabl e. Check steering gear assembly,
steering column assembly and front suspension components for
wear or damage if any of the turning angles are different from the
specified value. Replace any of them, if any non-standard condi-
tion exists.
Removal and Installation INFOID:0000000004305932
REMOVAL NOTE:
When reconnecting spiral cable, secure cable with a tape so that case and rotating part keep aligned. This will
omit neutral position alignment procedure during spiral cable installation.
1. Set front wheels to straight-ahead position.
2. Remove driver air bag module. Refer to SRS-34 .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel.
INSTALLATION Installation is in the reverse order of removal.

CAUTION:
• Do not allow axial impact to steering colu mn assembly during removal and installation.
• Steering column must be kept at maximum tilt up position during removal and installation. Do not
operate tilt mechanism while steeri ng column is out of the vehicle.
• Put matching mark on intermediate shaft and st eering column assembly before removing intermedi-
ate shaft.
• When steering wheel is turned re peatedly with the vehicle stopped, care must be taken because
motor and EPS control unit may get too hot.
• Steering column assembly is heavy . Care must be taken when removing steering column assembly
from vehicle.
• Do not put steering column assem bly near the things that generate excessive magnetic force.
• Steering column assembly (with motor, reduc tion gear, sensor) cannot be disassembled.
• Any time the ignition switch h as been removed and installed, the keys must be re-registered in the
BCM. Refer to CONSULT–III ope ration manual IVIS/NVIS.
REMOVAL 1. Set front wheels to straight ahead-position.
2. Remove driver air bag module. Refer to SRS-34 .
3. Remove steering wheel. Refer to PS-7, " Removal and Installation " .
4. Remove steering column cover (upper and lower). Refer to IP-11, " Component Parts " .
5. Remove combination switch and spiral cable. Refer to SRS-37 .
6. Remove instrument lower finisher. Refer to IP-11, " Component Parts " .

5. Loosen steering outer socket (1) mounting nut.
6. Remove steering outer socket (1) from steering knuckle (2) so as not to damage ball joint boot (3) using the ball joint remover
(suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover (suitable tool) from
suddenly coming off.
7. Remove front suspension member. Refer to FSU-11, " Removal and Installation " .
8. Remove mounting bolts and nuts of steering gear assembly.
INSTALLATION
Installation is in the reverse order of removal.
• Clean mounting surface on the body side of lower dash seal when installing steering gear assembly.
• Check wheel alignment under unladen conditions with tires on level ground. Refer to FSU-7, " Wheel Align-
ment Inspection " .
