CHECKING CONDITION OF INSTALLATION
●
Check the installation condition of the steering gear assembly, front suspension, axle and steering col-
umn.
●
Check if movement exists when the steering wheel is pushed up and down, left and right and in the axial
direction.
●
Check if the mounting nuts for the steering gear assembly are
loose. Refer to
PS-15, "POWER STEERING GEAR AND LINK-
CHECKING STEERING WHEEL PLAY
1.
Turn the tires straight ahead and start the engine. Lightly turn the steering wheel left and right to the point
where the tires start moving, and measure the distance that the outer circumference of the steering wheel
travels.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
●
Check the neutral position on the steering wheel after confirming the front wheel alignment is correct.
Refer to
FSU-6, "Front Wheel Alignment"
.
1.
Turn the tires straight ahead, check if the steering wheel is in the neutral position.
2.
If it is not in the neutral position, remove the steering wheel and reinstall it correctly on the steering stem,
within two teeth of the original position.
3.
If the neutral position cannot be attained by repositioning the steering wheel within two teeth on the steer-
ing stem, loosen the tie-rod lock nuts of the steering outer sockets, then adjust the tie-rods by the same
amount in the opposite direction of the steering wheel.
CHECKING STEERING WHEEL TURNING FORCE
1.
Park vehicle on a level, dry surface and set parking brake.
2.
Start engine.
3.
Bring the power steering fluid up to adequate operating temperature. Make sure the fluid temperature is
approximately 50
°
– 80
°
C (122
°
– 176
°
F).
4.
Tires need to be inflated to specified pressure. Refer to
5.
Check steering wheel turning force using Tool when steering
wheel has been turned 360
°
from the neutral position.
6.
If steering wheel turning force is out of specification, inspect the
following:
●
Steering column. Refer to
.
●
Power steering oil pump. Refer to
.

Removal and Installation
EGS0011H
REMOVAL
1.
Set the front wheels in the straight-ahead position.
2.
Remove the driver air bag module. Refer to
3.
Disconnect the steering wheel switches.
4.
Remove the steering wheel center nut.
5.
Remove the steering wheel, using Tools.
6.
Inspect the steering wheel near the puller holes for damage. If
damage is found, replace the steering wheel.
●
Remove the steering wheel rear cover and steering wheel
switches, if required.
CAUTION:
Place a piece of tape across the spiral cable so it will not be
rotated out of position.
INSTALLATION
Installation is in the reverse order of removal.
●
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 2.6 revolutions from the right
end position and ending with the locating pin at the top.
●
If equipped with VDC, refer to
BRC-128, "Adjustment of Steering
Angle Sensor Neutral Position"
for steering angle sensor adjust-
ment.
●
After the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer to
●
Tighten steering wheel center nut to specification. Refer to
PS-10, "Removal and Installation"
CAUTION:
●
The spiral cable may snap due to steering operation if the cable is not installed in the correct posi-
tion.
●
With the steering linkage disconnected, 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.

CAUTION:
When installing the steering column, finger-tighten all of the lower bracket and joint bolts; then tighten
them to specification. Do not apply undue stress to the steering column.
NOTE:
●
With the wheels in the straight ahead position, align the slit of
the lower joint with the projection on the dust cover. Insert the
joint until surface "A" contacts surface "B".
●
After installation, inspect the steering column for proper opera-
tion. Refer to
