Checking Fluid LevelEGS0004B
lCheck the fluid level with the engine OFF.
lCheck 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.
lNote 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:
lNever reuse drained power steering fluid.
lUse DEXRONTMIII or equivalent. Never use Nissan Power Steering Fluid Special, Nissan Matic
Fluid C, or D.
Checking Fluid LeakEGS0004C
Check hydraulic connections for any leak, 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.
lBubbles are created in reservoir tank.
lRattling noise can be heard from oil pump.
lWhiningnoisecanbeheardfromoilpump.
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(32to86°F)

becomes square to the carrier case.
lDo not reuse the pinion rear bearing outer race.
2. Using a drift, press a pinion front bearing outer race into the car-
rier case.
CAUTION:
lAt first, using a hammer, tap the bearing outer race until it
becomes square to the carrier case.
lDo not reuse the pinion front bearing outer race.
3. Using a drift, press a pinion rear bearing inner race into the drive
pinion gear.
CAUTION:
Do not reuse the pinion rear bearing inner race.
4. After checking and adjusting the tooth contact and backlash of
the hypoid gear following the procedure below, assemble a col-
lapsible spacer to the drive pinion gear.
CAUTION:
lBe careful of the mounting orientation of the collapsible
spacer.
lDo not reuse the collapsible spacer.
a. Apply differential oil to the pinion bearing, and assemble the
drive pinion gear to the carrier case.
CAUTION:
Do not assemble a collapsible spacer.

CHARGING SYSTEM
Trouble Diagnoses
EKS00319
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspection
Table.
lBefore starting, inspect the fusible link.
lUse fully charged battery.
WITH IC REGULATOR
NOTE:
lIf the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque.)
lWhen field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary, replace
faulty parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate “CHARGE” warning lamp, if any of the following
symptoms occur while alternator is operating:
lExcessive voltage is produced.
lNo voltage is produced.
Removal and InstallationEKS0031A
REMOVAL (QR ENGINE MODELS)
1. Disconnect battery ground cable.
2. Remove alternator drive belt. Refer toEM-13, "
Checking Drive Belts"in EM section.
