c. While pulling outer socket slowly in 11 . 5 m m (0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
d. If rack sliding force is not within specification, overhaul steering
gear assembly.
CHECKING FRONT WHEEL TURNING ANGLE
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 assem-
bly, steering column assembly and front suspension compo-
nents for wear or damage if any of the turning angles are
different from the specified value. Replace any of them, if any
non-standard condition exists.

Removal and InstallationNGS000D9
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SRS-38, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller [SST].
INSTALLATION
Reverse the removal procedure for installation attentive to the following operation.
NOTE:
The neutral position is set as follows.
Turn quietly the spiral cable clockwise to the end position. Then
turn it counterclockwise (about 2 and half turns) and stop turning
at the point on which the stopper insertion holes are in the same
position (showed as B in the figure). The service part is installed
in the neutral position by the stopper and can be set without
adjusting after the stopper is removed.
CAUTION:
Do not run spiral cable idle needlessly. And do not turn it more
than necessary (or it leads to disconnection of the cable).
Adjust the spiral cable locating pin (showed as A in the figure) to
the steering wheel locating pin hole (showed as C in the figure).

INSPECTION AFTER REMOVAL
Check each part of steering column assembly for damage or other malfunctions. Replace if there are.
Measure the length “L” as shown in the figure if vehicle has been
involved in a minor collision. Replace steering column assembly
if outside the standard.
Measure steering column rotating torque using preload gauge. Replace steering column assembly if out-
side the standard.
INSTALLATION OF STEERING COLUMN ASSEMBLY
Installation is the reverse order of removal. For tightening torque, refer to PS-13, "COMPONENTS" .
When installing upper joint, the angle which upper joint yoke (1)
forms with shaft center groove (A) should be at 90
.
Adjust neutral position of steering angle sensor. Refer to BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .
