+Align spiral cable correctly when installing steering wheel.
a) Set the front wheels in the straight-ahead position.
b) Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left 2.5 revolutions
from the right end position. Align the two marks (
).
CAUTION:
The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable may
snap by turning the steering wheel beyond the limited number
of turns. (The spiral cable can be turned up to 2.5 turns from
the neutral position to both the right and left.)

until surface A contacts surface B.
CAUTION:
After installation, turn steering wheel to make sure it moves
smoothly. Ensure the number of turns are the same from the
straight forward position to left and right locks. Be sure that
the steering wheel is in a neutral position when driving
straight ahead.

InspectionNJST0020+When steering wheel does not turn smoothly, check the steer-
ing column as follows and replace damaged parts.
a) Check column bearings for damage or unevenness. Lubricate
with recommended multi-purpose grease or replace steering
column as an assembly, if necessary.
b) Check jacket tube for deformation or breakage. Replace if
necessary.
+When the vehicle comes into a light collision, check length ªLº.
Steering column length ªLº:
Refer to SDS, ST-33.
If out of the specifications, replace steering column as an assem-
bly.

+Securely install boot band to boot groove and clinch the root
section of the trapezoidal area.
+Make sure that there is a clearance of 3.5 mm (0.138 in) or less
at the clinched section of the boot band. Refer to the Figure at
left.

+After installing gear in vehicle, make sure that the clinched
section of boot band is positioned toward the rear of vehicle (to
prevent interference with adjacent parts).

AdjustmentNJST0026Adjust pinion rotating torque as follows:
1. Set rack to the neutral position without fluid in the gear.
2. Coat the adjusting screw with locking sealant and screw it in.
3. Lightly tighten lock nut.
4. Tighten adjusting screw to a torque of 4.9 to 5.9 N´m (50 to 60
kg-cm, 43 to 52 in-lb).
5. Loosen adjusting screw, then retighten it to 0.2 N´m (2 kg-cm,
1.7 in-lb).
SST862CB
6. Move rack over its entire stroke several times.
7. Measure pinion rotating torque within the range of 180É from
neutral position.
Stop the gear at the point of maximum torque.
8. Loosen adjusting screw, then retighten it to 4.9 N´m (50 kg-cm,
43 in-lb).
9. Loosen adjusting screw by 50É to 70É.

11. Check rack sliding force on vehicle as follows:
a. Install steering gear onto vehicle, but do not connect tie-rod to
knuckle arm.
b. Connect all piping and fill with steering fluid.
c. Start engine and bleed air completely.
d. Disconnect steering column lower joint from the gear.
e. Keep engine at idle and make sure steering fluid has reached
normal operating temperature.
f. Pull tie-rod slowly to move it from neutral position to±11.5 mm
(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
Sedan
152 - 240 N (15.5 - 24.5 kg, 34.2 - 54.0 lb)
Hatchback
132 - 308 N (13.5 - 31.4 kg, 30 - 69 lb)
Maximum force deviation:
Sedan
98 N (10 kg, 22 lb)
Hatchback
176 N (17.9 kg, 39 lb)
g. Check sliding force outside above range at rack speed of 40
mm (1.57 in)/s.
Maximum rack sliding force (Sedan only):
294 N (30 kg, 66 lb)
Maximum force deviation (Sedan only):
147 N (15 kg, 33 lb)
+If rack sliding force is not within specification, readjust by
repeating adjustment procedure from the beginning.
+If rack sliding force is still out of specification after
readjustment, gear assembly needs to be replaced.

Precautions
PRECAUTIONSNJSU0001+When installing rubber parts, final tightening must be car-
ried out under unladen condition* with tires on ground.
Oil will shorten the life of rubber bushes. Be sure to wipe
off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+After installing removed suspension parts, check wheel
alignment and adjust if necessary.
+Use flare nut wrench when removing or installing brake
tubes.
+Always torque brake lines when installing.
+Lock nuts are unreusable parts; always use new ones.
When replacing, do not wipe the oil off the new lock nut
before tightening.
