• 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 adjustable. 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
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.

STEERING WHEEL
• Align spiral cable correctly when installing steering wheel. Makesure spiral cable alignment and centering marks (B) are matched
and in the neutral position. The neutra l position is detected by turn-
ing left 2.5 revolutions from the right end position, ending with the
locating pin (A) at the top. Place steering wheel in straight ahead
position, then install it with the locating pin hole (C) directly over
spiral cable locating pin.
• After the work is completed, perform self-diagnosis to make sure no malfunction is detected. Refer to SRS-19, "
SRS Operation
Check".

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 spiral cable. Refer to SRS-37
.
3. Remove instrument lower finisher. Refer to IP-11, "
Component Parts".
4. Disconnect each switch connector installed to steering column assembly, and then disconnect harness from steering column assembly.
5. Remove bolt of intermediate shaft (upper side), and then remove intermediate shaft from steering column assembly.

6. Remove steering column assembly mounting nuts, and then remove steering column assembly from vehi-cle.
7. Remove bolt of intermediate shaft (lower side), and then remove intermediate shaft from vehicle.
8. Remove screws of bracket and EPS control unit, and then remove bracket and EPS control unit from steering column assembly.
INSPECTION AFTER REMOVAL
• Check each part of steering column assembly, EPS control unit and intermediate shaft for damage and.replace as necessary.
• Measure the length “L” as shown, if vehicle has been involved in a minor collision. Replace steering column assembly (with motor,
reduction gear, sensor) if outside the standard.
• Check tilt mechanism for damage or other malfunctions. Replace
steering column assembly (with motor, reduction gear, sensor) as
necessary.
• Measure steering column assembly rotating torque using Tool. Replace steering column assembly (with motor, reduction gear, sensor) if outside the standard.
INSTALLATION
Installation is in the reverse order of removal.
• When tightening bolt (intermediate shaft lower side), tighten it by hand first, and make sure there is no feel-
ing of sticking or galling before final tightening.
CAUTION:
Insert bolt in the proper direction. (Do not insert it from the other side.)
• 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.
INSPECTION AFTER INSTALLATION
• Rotate steering wheel to check for decentered conditi on, binding, noise or excessive steering effort.
• After installing steering column assembly, perform self-diagnosis with CONSULT-III to ensure correct opera-
tion. Refer to STC-8, "
CONSULT-III Function".

INSPECTION AFTER DISASSEMBLY
Joint Cover
Check joint cover protrusion for damage. Replace if there are.
Rack and Pinion Assembly
• Check pinion assembly for damage or wear. Replace as necessary.
• Rotate pinion assembly and check for torque variati on or rattle. Replace steering gear as necessary.
Gear Housing Assembly
Check gear housing assembly for damage or scratches. Replace steering gear as necessary.
Outer Socket and Inner Socket
1. Check ball joint swinging torque.
• Hook a spring balance at the point shown and pull the spring
balance. Make sure that the spring balance reads the speci-
fied value when ball stud and inner socket start to move.
Replace outer socket and inner socket if they are outside the
standard.
2. Ball joint axial end play • Apply an axial load of 490 N (50 kg-f, 111 lb-f) to ball stud.Measure amount of stud movement using a dial gauge, and
then make sure that the value is within the specified range.
