NEUTRAL POSITION STEERING WHEEL
1.
Check that steering gear assembly, steering column assembly and steering wheel are installed in the cor-
rect position.
2.
Perform neutral position inspection after wheel alignment. Refer to
3.
Set the vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
4.
Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
STEERING WHEEL TURNING FORCE
1.
Park the vehicle on a level and dry surface, set parking brake.
2.
Tires need to be inflated normal pressure. Refer to
3.
Start the engine.
4.
Bring power steering fluid up to adequate operating temperature.
5.
Check steering wheel turning force when steering wheel has
been turned 540
°
from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
6.
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 to
.
RACK SLIDING FORCE
1.
Disconnect lower joint and steering knuckle from steering gear assembly. Refer to
.
2.
Start and run the engine at idle to make sure steering fluid has reached normal operating temperature.
3.
While pulling outer socket slowly in
±
11.5 mm (
±
0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
4.
If rack sliding force is not within specification, overhaul steering
gear assembly.

2.
Place front wheels on turning radius gauges and rear wheels on
stands, so that vehicle can be level.
3.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
4.
With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.
5.
Check the following items when turning angle is out of the stan-
dard.
a.
Check the neutral position of the rack stroke (L).
b.
Disassemble steering gear assembly to check the cause that
rack stroke is outside of the standard.
• Steering angles are not adjustable. Check steering gear
assembly, steering column assembly and front suspension
components 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.
