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-19, "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-24, "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 176°F).]
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 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 PS-30,
"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 N·m (0.76 kg-m, 66 in-lb)

Removal and InstallationNGS000D9
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SRS-42, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller [SST].
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-13, "COMPONENTS" .
NOTE:
Check the spiral cable neutral position after replacing or rotating spiral cable. Refer to SRS-44, "
INSTALLA-
TION" .
CAUTION:
Do not twist spiral cable freely on excessively after it becomes tight (doing so may cause the cable to
be turn off).

CAUTION:
Do not damage inner socket and gear housing assembly when removing boot. Inner socket and
gear housing assembly must be replaced if inner socket and gear housing assembly are damaged
because it may cause foreign material interfusion.
9. Remove inner socket from gear housing assembly.
10. Drill out the clinching part of gear housing assembly (end cover
assembly side) outer rim with a 3 mm (0.12 in) drill bit. [Drill for
approximately 1.5 mm (0.059 in) depth.]
11. Remove end cover assembly with a 36 mm (1.42 in) open head
(suitable tool).
CAUTION:
Do not damage rack assembly surface when removing.
Rack assembly must be replaced if damaged because it
may cause fluid leakage.
12. Pull rack assembly together with rack oil seal (outer side) out
from gear housing assembly.
CAUTION:
Do not damage cylinder inner wall when removing rack
assembly. Gear housing assembly must be replaced if dam-
aged because it may cause fluid leakage.
13. Heat rack Teflon ring to approximately 40°C (104°F) with a
dryer, and remove rack Teflon ring and O-ring from rack assem-
bly.
CAUTION:
Do not damage rack assembly. Rack assembly must be
replaced if damaged because it may cause fluid leakage.

12. Apply recommended thread locking sealant to the thread (2
turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
13. Move rack assembly 10 strokes throughout the full stroke so that
the parts can fit with each other.
14. Measure pinion rotating torque within ±180° of neutral position
of the rack assembly using the preload gauge [SST] and preload
adapter [SST]. Stop the gear at the point where highest torque is
read.
15. Loosen adjusting screw and retighten to 5.4 N·m (0.55 kg-m, 48
in-lb), and then loosen by 20 to 40°.
16. Measure pinion rotating torque using the preload adapter [SST]
and preload gauge [SST] to make sure that the measured value
is within the standard. Readjust if the value is outside the stan-
dard. Replace steering gear assembly if the value is outside the
standard after readjusting or adjusting screw rotating torque is 5
N·m (0.51 kg-m, 44 in-lb) or less.
17. Apply recommended liquid gasket to inner socket and turn pinion fully to left with inner socket installed to
gear housing assembly.
18. Set dial gauge as shown in the figure. Measure vertical move-
ment of rack assembly when pinion is turned clockwise with
torque of 19.6 N·m (2.0 kg-m, 14 ft-lb). Readjust adjusting screw
angle if the measured value is outside the standard. Replace
steering gear assembly if the measured value is still outside the
standard or adjusting screw rotating torque is 5 N·m (0.51 kg-m,
44 in-lb) or less.
