STEERING WHEEL
Revision: 2006 January2006 M35/M45
STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceNGS000D8
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 nut for looseness. Refer to PS-18, "COMPONENTS" .
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 FSU-6, "Wheel Alignment Inspection"
(2WD), FSU-23, "Wheel Alignment Inspection" (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 176F).]
4. Check steering wheel turning force when steering wheel has
been turned 540
from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring scale to the
center of steering wheel by the measurement value with a spring
scale.
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 PS-29,
"CHECKING RELIEF OIL PRESSURE" .
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to PS-13, "
COMPO-
NENTS" , FAX-5, "COMPONENT" .
b. Start and run engine at idle to make sure steering fluid has reached normal operating temperature. Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Steering wheel turning
force: 7.45 Nꞏm (0.76 kg-m, 66 in-lb)

–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower joint (C) aligning with the projection (A) of
rear cover cap (1). Make sure that the slit part of lower joint (C)
is aligned with both the projection (A) of rear cover cap (1) and
the marking position (B) of gear housing assembly.
Adjust neutral position of steering angle sensor. Refer to BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .
REMOVAL OF STEERING COLUMN ASSEMBLY
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SRS-38, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel. Refer to PS-12, "
Removal and Installation" .
4. Remove steering column cover. Refer to IP-10, "
INSTRUMENT PANEL ASSEMBLY" .
5. Remove combination switch & spiral cable. Refer to SRS-40, "
SPIRAL CABLE" .
6. Remove instrument driver lower panel. Refer to IP-10, "
INSTRUMENT PANEL ASSEMBLY" .
7. Remove fixing bolts of knee protector (1), then remove knee
protector (1) from vehicle.
8. Remove low tire pressure warning control unit. Refer to WT-40,
"Low Tire Pressure Warning Control Unit" .
9. Disconnect each switch connectors installed to steering column
assembly, and then disconnect harness from steering column
assembly.
10. Remove fixing bolt of upper joint (1) (steering column assembly
side).
11. Remove steering column assembly mounting bolts and nut, then
remove steering column assembly from vehicle.

STEERING COLUMN
Revision: 2006 January2006 M35/M45
INSPECTION AFTER REMOVAL
Check each part of steering column assembly for damage or other malfunctions. Replace if there are.
Measure the length “L” as shown in the figure if vehicle has been
involved in a minor collision. Replace steering column assembly
if outside the standard.
Measure steering column rotating torque using preload gauge. Replace steering column assembly if out-
side the standard.
INSTALLATION OF STEERING COLUMN ASSEMBLY
Installation is the reverse order of removal. For tightening torque, refer to PS-13, "COMPONENTS" .
When installing upper joint, the angle which upper joint yoke (1)
forms with shaft center groove (A) should be at 90
.
Adjust neutral position of steering angle sensor. Refer to BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .
INSPECTION AFTER INSTALLATION
Make sure that steering wheel operates smoothly by turning several times from full left stop to full right stop.
