Steering Wheel: Procedures
STEERING WHEEL
On-Vehicle Inspection and Service
CHECKING CONDITION OF INSTALLATION
-
Check installation conditions of steering gear assembly, front suspension assembly, axle and steering column assembly.
-
Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial direction.
Standard
Steering wheel axial end play : Refer to See: Specifications.
-
Check steering gear assembly mounting bolts and nut for looseness. Refer to See: Steering Gear/Service and Repair/Removal and Replacement.
CHECKING STEERING WHEEL PLAY
-
Turn 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.
Standard
Steering wheel axial end play : Refer to See: Specifications.
-
When the measurement value is outside the standard value, check backlash for each joint of steering column assembly and installation condition of
steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
-
Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the correct position.
-
Perform neutral position inspection after wheel alignment. Refer to See: Alignment/Service and Repair/Front Suspension(2WD), See:
Alignment/Service and Repair/Front Suspension (AWD).
-
Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
-
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.
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 (122 to 176°F).]
4. Check steering wheel turning force when steering wheel has been turned 540° from neutral position.
Standard
Steering wheel axial end play : Refer to See: 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.
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 to See: Power Steering/Power Steering Pump/Testing and Inspection.
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to See: Steering Column/Service and Repair/Removal and
Replacement, .
b. Start and run engine at idle to make sure steering fluid has reached normal operating temperature.
