Checking Power Steering Fluid and LinesNLS00070
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80 °C (122 to 176 °F)
or “COLD” range at fluid temperatures of 0 to 30 °C (32 to 86 °F).
CAUTION:

Do not overfill.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS"


Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.

Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS00071
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.

Shake each wheel to check for excessive play.

Check wheel bearings for smooth operation.

Check axle and suspension nuts and bolts for looseness.

Check strut (shock absorber) for oil leakage or other damage.

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.

Checking Fluid LevelNGS000BT

Stop engine before performing a fluid level check.

Ensure that fluid level is between the MAX range and MIN level.

Because fluid level differs within the HOT range and the COLD
range, check it carefully.
CAUTION:

Do not overfill the Max level.

Do not reuse any used power steering fluid.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Checking Fluid LeakageNGS000BU
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50 to 80 ° C (122 to
176 °F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over tighten con- nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-29, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating a from steering gear.
Air Bleeding Hydraulic SystemNGS000BV
Incomplete air bleeding causes the following. When this happens, bleed air again.

Generation of air bubbles in reservoir tank.

Generation of clicking noise in oil pump.

Excessive buzzing in oil pump.
NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from
oil pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times. CAUTION:
Do not allow steering fluid reservoir tank to go below the low-level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully to the right and then fully to the left, and keep for about three seconds. Then check whether a fluid leakage has occurred.
3. Repeat the 2nd procedure several times at about three seconds intervals. CAUTION:
Do not hold steering wheel in the locked position more than 10 seconds. (There is the possibility
that oil pump may be damaged.)
4. Check generation of air bubbles and cloud in fluid. HOT : Fluid temperatures from 50 to 80
°C (122 to
176 °F)
COLD : Fluid temperatures from 0 to 30 °C (32 to 86 °F)

On-Vehicle Inspection and ServiceNGS000BW
CHECKING CONDITION OF INSTALLATION

Check installation condition of steering gear assembly, front suspension, axle and steering column.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

Check if the mounting bolts for steering gear assembly are loose
or not. Refer to PS-17, "
POWER STEERING GEAR AND LINK-
AGE" .
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumference when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
6, "Wheel Alignment Inspection" .
1. Set vehicle to the straight direction, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock nuts of steering outer sockets, then adjust outer socket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Remove driver air bag module from steering wheel. Refer to SRS-38, "
DRIVER AIR BAG MODULE" .
3. Start engine at idle, make steering fluid reach to normal operat- ing temperature [50 to 80 °C (122 to 176 °F)], then check steering
wheel turning torque with pre-load gauge (SST).
4. If steering wheel turning force is out of the specification, check relief hydraulic pressure of oil pump. Refer to PS-29, "
POWER
STEERING OIL PUMP" .
End play of the axle direction for steering wheel : 0 mm (0 in)

CHECKING RELIEF OIL PRESSURE (VQ35DE MODELS)
CAUTION:
Before starting work, confirm belt tension is proper.
1. Connect oil pressure gauge (SST) and oil pressure gauge adapter (SST) between oil pump discharge connector and high
pressure hose and then bleed air from the hydraulic circuit.
2. Start engine. Allow engine to run until tank temperature reaches 50 to 80 °C (122 to 176 °F).
CAUTION:

Warm up engine with shut-off valve fully opened. If
engine is started with shut-off valve closed, fluid pres-
sure in power steering pump increases to maximum. This
will raise fluid temperature excessively.

Be careful not to contact hose with belt when engine is
started.
3. With engine at idle, close shut-off valve and read the relief oil pressure.
CAUTION:
Do not close shut-off valve of pressure gauge for more than 10 seconds.
4. After measurement, open shut-off valve slowly. If relief oil pressure is outside the specification, disassemble and repair oil pump. Refer to PS-31, "
Disas-
sembly and Assembly (VQ35DE Models)" .
5. After inspection, disconnect oil pressure gauge (SST) and oil pressure gauge adapter (SST) from hydrau- lic circuit, connect oil pump discharge connector and high pressure hose. Add fluid and bleed air from
hydraulic circuit thoroughly.
Refer to PS-8, "
