REMOVAL
1. Set the front wheels in the straight-ahead position.
2. Remove the driver air bag module. Refer to SR-5, "Removal and Installation"
.
3. Disconnect steering wheel switches.
4. Remove the steering wheel center nut.
5. Remove the steering wheel using Tool.
CAUTION:
Place a piece of tape across the sp iral cable so it will not be
rotated out of position.
6. Disconnect heated steering wheel connector.
7. Inspect the steering wheel near the puller holes for damage. If damaged, replace the steering wheel.
 Remove steering wheel rear cover and steering wheelswitches, if required.
INSTALLATION
Installation is in the reverse order of removal.
 Refer to BRC-8, "ADJUSTMENT OF STEERING ANGLE SEN-
SOR NEUTRAL POSITION : Special Repair Requirement" for
steering angle sensor adjustment.
 Align spiral cable correctly when installing steering wheel. Make sure that the spiral cable is in the neutral position. The neutral
position is detected by turning left 2.5 revolutions from the right
end position and ending with the knob at the top.
 After the work is completed, perform self-diagnosis to make sure no malfunction is detected. Refer to SRC-13, "SRS Operation
Check".
 Tighten steering wheel center nut to specification. SR-7, "Removal
and Installation".
CAUTION:
 The spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
 With the steering linkage di sconnected, the cable may snap
by turning the steering wheel beyond the limited number of
turns. The spiral cable can be turned counterclockwise about
2.5 turns from the neutral position. Tool number : ST27180001 (J-25726-A)

INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
 When installing the steering column, finger-tighten all of the lower bracket and joint retaining bolts;
then tighten them to specifi cation. Do not apply undue st ress to the steering column.
 The lower nut on the upper joint may not be reused.
 After installation, turn steering wheel to make sure it moves smoothly. Make sure the number of turns are the
same from the straight-forward position to left and right locks. Make sure that the steering wheel is in a neu-
tral position when driving straight ahead.
 When installing steering column to steering mem ber, install nut from front side of vehicle.
INSPECTION AFTER INSTALLATION
 After installing steering column to vehicle, check tilt device operation range is within specification.
