CHECKING CONDITION OF INSTALLATION
lCheck installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
lCheck if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
lCheck steering gear assembly mounting bolts and nuts for looseness. Refer toPS-14, "COMPONENT".
CHECKING STEERING WHEEL PLAY
lTurn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on
the outer circumference.
lWhen the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
lMake sure that steering gear assembly, steering column assembly and steering wheel are installed in the
correct position.
lPerform neutral position inspection after wheel alignment. Refer toFSU-7, "Front Wheel Alignment".
lSet vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
lLoosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustment if
steering wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is
approximately 50 to 80°C(122to176°F).]
4. Check steering wheel turning force when steering wheel has
been turned 360°from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring scale to the
center of steering wheel by the measurement value with a spring
scale.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer toPS-25,
"CHECKING RELIEF OIL PRESSURE".
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer toPS-11, "
COMPO-
NENT",FAX-5, "Removal and Installation".
b. Start and run engine at idle to make sure steering fluid has reached normal operating temperature.Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Steering wheel turn-
ing force: Less than 39 N (4.0 kg-m, 8.8 lb)

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
lCheck 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.
lWith the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.
lMeasure rack stroke if angles are outside the specified value.
lDisassemble steering gear assembly to check the cause that
rack stroke is outside of the standard.
lSteering 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.Rack sliding force: 210 - 270 N

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 installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer toSRS-36, "
DRIVER AIR BAG MODULE".
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller [SST:
ST27180001] (A).
INSTALLATION
Reverse the removal procedure for installation attentive to the following operation.
NOTE:
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.
CAUTION:
Do not run spiral cable idle needlessly. And do not turn it more
than necessary (or it leads to disconnection of the cable).
