STEERING WHEEL AXIAL END PLAY
1.Check installation conditions of steering gear assembly, front suspension assembly, axle and steering column assembly.
2.Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial direction.
Steering wheel axial end play: Refer to "Steering Wheel Axial End Play". Specifications
3.Check the following items when steering wheel axial end play is out of the standard.
- Check the steering column assembly mounting condition. Refer to "WITHOUT ELECTRIC MOTOR : Exploded View" Exploded View (Without electric motor), "WITH ELECTRIC MOTOR : Exploded View" Exploded View
(With electric motor).
- Check steering gear assembly mounting condition for looseness. Refer to "Exploded View" Exploded View.
STEERING WHEEL PLAY
1.Turn steering wheel so that front wheels come to the straight-ahead position.
2.Start engine and lightly turn steering wheel to the left and right until front wheels start to move.
3.Measure steering wheel movement on the outer circumference.
Steering wheel play: Refer to "Steering Wheel Axial End Play and Play".
4.Check the following items when steering wheel play is out of the standard.
- Check backlash for each joint of steering column assembly.
- Check installation condition of steering gear assembly.
NEUTRAL POSITION STEERING WHEEL
1.Check that steering gear assembly, steering column assembly and steering wheel are installed in the correct position.
2.Perform neutral position inspection after wheel alignment. Refer to "Inspection" Wheel Alignment Inspection.
3.Set 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 vehicle on a level and dry surface, set parking brake.
2.Tires need to be inflated normal pressure. Refer to "Tire Air Pressure" [1][2]Specifications.
3.Start 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.
Steering wheel turning force : Refer to "Steering Wheel Turning Force". Specifications
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 "EXCEPT FOR SPORT MODELS :
Inspection" (Except for sport models), "SPORT MODELS : Inspection" Inspection Sport Models (Sport models).
RACK SLIDING FORCE
1.Disconnect lower joint and steering knuckle from steering gear assembly. Refer to "Exploded View" Exploded View.
2.Start and run 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.
Rack sliding force: Refer to "Rack Sliding Force" Rack Sliding Force.
4.If rack sliding force is not within specification, overhaul steering gear assembly.
FRONT WHEEL TURNING ANGLE
1.Check front wheel turning angle after toe-in inspection. Refer to "Inspection" Wheel Alignment Inspection.
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.
Inner wheel (Angle: A): Refer to "Steering Angle" Steering Angle.
Outer wheel (Angle: B): Refer to "Steering Angle" Steering Angle.
5.Check the following items when turning angle is out of the standard.
a.Check the neutral position of the rack stroke (L).
Rack stroke neutral position (L): Refer to "Rack Stroke" Specifications.
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.
