4. Using a preload gauge, measure the preload torque of the pin-
ion bearing.
CAUTION:
Every rotational part shall rotate smoothly with the speci-
fied gear oil.

If measured value is out of the specification, disassemble the
pinion sleeve assembly to check and adjust each part.
Total Preload Torque
1. Measure pinion bearing preload torque (P1 ). Refer to TF-60, "Pinion Bearing Preload Torque" .
2. Install the pinion sleeve shims and pinion sleeve assembly.
3. Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
4. Using a preload gauge, measure the total preload torque.

If measured value is out of the specification, disassemble it to
check and adjust each part. If measuring the total preload
torque after the disassembly, measure it with the transfer case oil seals and gear ring oil seals
removed, then install the oil seals.
Companion Flange Runout
1. Fit a dial gauge onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate the companion flange to check for runout.
3. Fit a test indicator to the inner side of the companion flange
(socket diameter).
4. Rotate the companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. While changing the phase between companion flange and drive pinion gear by 90° at a time, check runout
and determine which phase angle minimizes the runout.
b. If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c. If the runout is out of the specification after replacement of companion flange, adjust the assembly status
of the pinion bearings and drive pinion gear, or replace the pinion bearings.Tool number : ST3127S000

TROUBLE DIAGNOSIS

For Fast and Accurate DiagnosisEFS004H8
PRECAUTIONS FOR DIAGNOSIS

Before performing diagnosis, always read precautions. Refer to BRC-58, "How to Proceed With Diagno-
sis" .

If ESP/TCS/ABS control unit steering angle sensor, steering system parts or suspension system parts
have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of steering angle
sensor before driving. Refer to BRC-51, "
Adjustment of Steering Angle Sensor Neutral Position" .

After diagnosis is finished, be sure to erase memory. Refer to BRC-79, "SELF-DIAGNOSIS" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

To use CONSULT-II to perform self-diagnosis of ESP/TCS/ABS control unit active tests, or work support,
first stop work, then connect CONSULT-II and select “ABS”.

While self-diagnostic results of CONSULT-II shows malfunction, if CONSULT-II active test is performed,
an engine system error may be indicated. In this case, start engine to resume the normal screen.

ESP/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:
Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ESP/TCS/ABS control unit. Slight noise
may occur during ESP, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and
valves operating noise may be heard. It happens only once after IGN
(ignition) is ON. This is a normal status of the system operation check.
System operation check
noiseWhen engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check.Normal
ESP/TCS operation
(SLIP indicator lamp blink-
ing)TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when up/downshifting, or
when fully depressing accelerator pedal.
Normal
Cancel the ESP/TCS
function for the
inspection on a chas-
sis dynamometer. For inspection of speedometer or other instruments, press ESP OFF
SW to turn ESP/TCS function off.
When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is
result of TCS being activated by stationary front wheels. Warning lamp
may also illuminate to indicate “sensor system error”. This is also nor-
mal, and is the result of the stationary front wheels being detected. To be
certain, restart engine, and drive vehicle at 30 km/h (19 MPH) or more.
Make sure warning lamp does not illuminate.
ABS operation (Longer stop-
ping distance)On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.Normal
Insufficient feeling of accel-
erationDepending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.Normal

POWER STEERING FLUID

POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelEGS0004B

Check the fluid level with the engine OFF.

Check that fluid level is between MAX and MIN marks on tank.
Fluid level should not exceed MAX mark. Excessive fluid will
cause fluid to leak from cap.

Note that fluid level can change depending on temperature of
fluid. HIGH and LOW marks are shown on tank to indicate the
proper level at high temperature and low temperature respec-
tively.
CAUTION:

Never reuse drained power steering fluid.

Use DEXRONTM III or equivalent. Never use Nissan Power Steering Fluid Special, Nissan Matic
Fluid C, or D.
Checking Fluid LeakageEGS0004C
Check hydraulic connections for any leakage, crack, damage, loose-
ness, or wear.
1. Run engine until fluid temperature reaches 50 to 80°C (122 to
176°F) in reservoir tank. Keep engine speed at idle.
2. Turn steering wheel several times from stop to stop.
3. Turn the steering wheel clockwise or counter clockwise until it
reaches the stop and hold it for five seconds. Check for fluid
leak.
CAUTION:
Do not hold steering wheel at stop for 15 seconds or longer.
Otherwise, pump may be damaged.
4. If any leak is found on joint, loosen and retighten flair nut. Excessive tightening may damage O-ring,
washer, or connector.
Bleeding Hydraulic SystemEGS0004D
1. Lift vehicle.
2. Fill tank up to MAX mark. Turn steering wheel several times from stop to stop. Add fluid if fluid level goes
down. Repeat this step until there is no fluid decrease and no bubble in tank.
3. Start engine and repeat step above with engine at idle. Continue step until no decrease in fluid happens.
If bleeding is not complete, following symptoms can be observed.

Bubbles are created in reservoir tank.

Rattling noise can be heard from oil pump.

Whining noise can be heard from oil pump.
Turn steering wheel slowly or stop vehicle. Sound of fluid movement may be heard from gear valve and
pump. This sound has nothing to do with steering performance or durability.HOT : Oil temperature 50 to 80°C (122 to 176°F)
COLD : Oil temperature 0 to 30°C (32 to 86°F)
