STEERING WHEEL AXIAL END PLAY
1. Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
2. Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
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 ST-13, "
Exploded View".
 Check steering gear assembly mounting condition for looseness. Refer to ST-18, "
Exploded View".
STEERING WHEEL PLAY
1. Turn steering wheel so that front wheels come to the straight-ahead position.
2. Start the 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.
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 cor-
rect position.
2. Perform neutral position inspection after wheel alignment. Refer to FSU-7, "
Wheel Alignment Inspection".
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 WT-5, "
Tire Air Pressure".
3. Start the engine.
4. Bring power steering fluid up to adequate operating temperature.Standard
