CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
4. If fluid leakage at connectors is noticed, loosen flare nut and
then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
5. Check rack boots for accumulation of power steering fluid.
Bleeding Hydraulic SystemNBST00131. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Then, quickly turn
steering wheel fully to right and left and lightly touch steering
stoppers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2 above.
IIncomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a) Air bubbles in reservoir tank
b) Clicking noise in oil pump
c) Excessive buzzing in oil pump
Fluid noise may occur in the valve or oil pump. This is common
when the vehicle is stationary or while turning steering wheel
slowly. This does not affect performance or durability of the system.

Checking Steering Wheel Turning ForceNBST00141. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80ÉC (140 to 176ÉF).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from the neutral position.
Steering wheel turning force:
39 N (4 kg, 9 lb) or less
5. If steering wheel turning force is out of specification, check
rack sliding force.
a. Disconnect steering column lower joint and knuckle arms from
the gear.
b. Start and run engine at idle to make sure steering fluid has
reached normal operating temperature.
c. 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.
Rack sliding force:
137 - 255 N (14 - 26 kg, 31 - 57 lb)

FRONT WHEEL ALIGNMENTNBSU0006Before checking front wheel alignment, be sure to make a prelimi-
nary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
Preliminary InspectionNBSU0006S011. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage.
If deformed, remove wheel and check wheel runout.
NOTE:
Measure both the inner and outer sides for the radial runout and
lateral runout, and confirm the figures are within the standards.
Wheel runout (Dial indicator value):
Refer to SDS.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly.
7. Check vehicle posture (Unladen).

Camber, Caster and Kingpin InclinationNBSU0006S02Camber, caster and kingpin inclination are preset at factory
and cannot be adjusted.
1. Measure camber, caster and kingpin inclination of both right
and left wheels with a suitable alignment gauge.
Camber, Caster and Kingpin inclination:
Refer to SDS, SU-13.
2. If camber, caster or kingpin inclination is not within
specification, inspect front suspension parts. Replace dam-
aged or worn out parts.
