On-Vehicle Inspection and ServiceINFOID:0000000001282496
CHECKING CONDITION OF INSTALLATION
 Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
 Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
 Check steering gear assembly mounting bolts and nuts for looseness. Refer to ST-12, "
Removal and Instal-
lation" .
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.
 When 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
 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 SR-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"" .
 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 steer-
ing 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. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position using suitable tool as
shown.
4. If steering wheel turning force is out of the specification, refer to
STC-3, "
Work Flow" .
CHECKING FRONT WHEEL TURNING ANGLE
Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Steering wheel
turning force: Less than 36 N (3.7 kg-f, 8.2 lb-f)

and to prevent the ball joint remover (suitable tool) from
suddenly coming off.
7. Remove front suspension member. Refer to FSU-11, "
Removal and Installation".
