On-Vehicle Inspection and ServiceAGS000GW
CHECKING CONDITION OF INSTALLATION

Check installation condition of steering gear assembly, front suspension, axle and steering column.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

Check if the mounting bolts for steering gear assembly are loose
or not. Refer to PS-19, "
POWER STEERING GEAR AND LINK-
AGE" .
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumference when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
6, "Wheel Alignment Inspection" .
1. Set vehicle to the straight direction, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock
nuts of steering outer sockets, then adjust outer socket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Remove driver air bag module from steering wheel. Refer to SRS-36, "
DRIVER AIR BAG MODULE" .
3. Start engine at idle, make steering fluid reach to normal operat-
ing temperature [50 to 80°C (122 to 176°F)], then check steering
wheel turning torque with pre-load gauge (SST).
4. If steering wheel turning force is out of the specification, check
relief hydraulic pressure of oil pump. Refer to PS-31, "
POWER
STEERING OIL PUMP" . End play of the axle direction for steering wheel : 0 mm (0 in)
SGIA0546E
Steering wheel play on the outer circumference : 0 − 35 mm (0 − 1.38 in)
Turning torque : 7.45 N·m (0.76 kg-m, 66 in-lb) or less

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)
