STEERING WHEEL
STEERING WHEEL
On-Vehicle Inspection and ServiceINFOID:0000000006416714
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 mo ved up and down, to the left and right and to the axial
direction.
• Check steering gear assembly bolts and nuts for looseness. Refer to PS-15, "
Removal and Installation".
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 val ue, 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 PS-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"".
• Set vehicle to the straight-ahead position and c onfirm 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
Tool as shown.
4. If steering wheel turning force is out of the specification, refer to GI-9, "
How to Follow Trouble Diagnosis".
CHECKING FRONT WHEEL TURNING ANGLE
Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Tool number : — (J-44372)
Steering wheel
turning force : Less than 36 N (3.7 kg-f, 8.2 lb-f)

3. Install inner socket to rack assembly. Torque to specified value while holding the flat portion of the racknext to the inner socket using a suitable tool.
4. Apply recommended grease to inner socket.
5. Decide on the neutral position for the rack assembly.
6. Apply recommended grease to around retainer (3), then install retainer (3), spring (4) and adjusting screw (1) to gear housing
assembly (5).
7. Apply recommended thread locking sealant to the thread (2 turns thread), and then screw in the adjusting screw (1) until it
reaches height “H” from gear housing assembly (5) measured
before disassembling.
8. Tighten lock nut to (2) the specified torque securing it to prevent adjusting screw (1) from freewheeling condition.
9. Move rack assembly 10 strokes throughout the full stroke so that the parts can fit with each other.
10. Using Tools A and B, measure rotating torque of pinion assem- bly. If the measurement is out side of the specified range, read-
just pinion rotating torque. If the measurement is outside of the
specified range for readjust, replace steering gear assembly.
11. Set dial gauge to the back of rack assembly on the pinion assembly side around the center of stroke. Measure displace-
ment of rack under torsional torque of ± 7.8 N·m (0.80 kg-m, 69
in-lb), and then check if it is within the standard value. If the
measurement is outside the standard value, adjust it again. After
the readjustment, if measurement is still outside the standard
value, replace steering gear assembly.
12. Install boot to gear housing assembly and inner socket. Rack stroke “L” : Refer to
PS-21, "
Steering Gear".

13. Install boot clamp (1) to boot using Tool. NOTE:
Install large diameter side boot clamp (1) securely to boot
groove, and crimp it so as to have clearance of 3 mm (0.12 in) or
less as shown.
14. Install joint cover (1) to gear housing assembly (2). CAUTION:
Install joint cover so that the protrusion for locating is
securely set to gear housing groove.
15. Adjust inner socket to standard length “L”, and then tighten lock nut to the specified torque. Check length of inner socket “L”
again after tightening lock nut. Make sure that the length is the
standard.
CAUTION:
Adjust toe-in. Refer to FSU-7, "
Wheel Alignment Inspec-
tion". Length achieved after toe-in adjustment is not neces-
sarily the above value. Tool number : KV40107300 ( — )
