CHECKING FRONT WHEEL TURNING ANGLE

Check front wheel turning angle after the toe-in inspection.
Place front wheels on turning radius gauges and rear wheels on
stands so that vehicle can be level. Check the maximum inner
and outer wheel turning angles for LH and RH road wheels.

Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.

Any turning angles are not adjustable. If any of steering angles
are out of the specification, check if the following parts are wear
or damaged.
–Steering gear
–St ee rin g c o lum n
–Front suspension components
If found that they are worn or damaged, replace them with new ones respectively.

INSPECTION AFTER REMOVAL

Check if there is something wrong with jacket tube of steering column assembly and collar etc. And then if
they are damaged, replace with new one.

If vehicle has a collision light shocked, check column length “L”
as shown in the figure. Then if it is out of the specified value,
replace with new one.

Check the turning torque of steering column with preload gauge
(SST). If it is out of the specified value, repair it or replace with
new one.
INSTALLATION

Refer to PS-12, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
INSPECTION AFTER INSTALLATION

After installing steering column to vehicle, check tilt device and
its operation range. Ranges of operation are shown in the figure.

Check if steering wheel operation can turn to the end of the left
and right smoothly.Steering column length “L”: 572 mm (22.52 in)
Turning torque : 0 − 0.2 N·m (0 − 0.021 kg-m, 0 − 1 in-lb)
