PRE-INSPECTION
lCheck the clearance between side gear and differential case as
follows.
1. Clean final drive assembly sufficiently to prevent side gear thrust
washer, differential case, side gear, and other parts from sticking
by gear oil.
2. Upright the differential case so that the side gear to be measured faces upward.
3. Place final drive adapter and dial gauge onto side gear. Move
side gear up and down, and measure the clearance.
4. If not within specification, adjust the clearance by changing
thrust washer thickness.
5. Turn differential case upside down, and measure the clearance
between side gear and differential case on the other side in the
same way.
DISASSEMBLY
1. Remove mounting bolts.Then, separate the final gear from differential case.
2. Using a drift and puller, remove differential side bearing (clutch
housing side).
3. Using a drift and puller, remove differential side bearing (tran-
saxle case side).

Precautions for models with SRS air bag and pre-tensioner seat beltEGS00048
WAR NIN G:
lBefore removing and installing components and harnesses of SRS air bag and seat belt pre-ten-
sioner system, turn ignition switch OFF, disconnect battery ground cable, and wait at least 3 min-
utes. (This discharges electricity held in the air bag sensor unit's additional power circuit.)
lDo not use pneumatic or electric tools to remove and install the components.
lDo not solder SRS air bag and seat belt pre-tensioner system harnesses when making repairs.
Make sure harness is not pinched and there is no contact with other components.
lWhen checking the SRS air bag and the seat belt pre-tensioner circuit or the components of each
system, do not use an electric tester such as a circuit tester. (This is to prevent accidental trigger-
ing caused by the weak electric current of a tester.)
lNever insert foreign material (such as a screwdriver) in the air bag module and pre-tensioner seat
belt connectors. (The units may be actuated by mistake by static electricity.)
lSeat belt pre-tensioner and SRS air bag harnesses can be distinguished from other harnesses by
their yellow connectors.
lWhen servicing, refer to “SB Seat Belt” and “SRS Air Bag” for safety.
CautionEGS00049
lAlways follow the warnings and the cautions below in disassembly procedures:
–Work in a clean, dust-free place. No dust proof device is necessary.
–Clean outside of unit before disassembly.
–Clean parts to be disassembled. Be careful not to allow any dirt or other foreign materials to enter or con-
tact with parts.
–Assemble disassembled parts properly, following order shown in manual. If work has been suspended in
the middle of assembly, place a clean cover over parts. This will prevent them from being contaminated.
–Use paper towels when removing dirt and other foreign materials. Cloth shop towels can leave lint on
cleaned parts that might affect operation of parts.
–Clean disassembled parts (except rubber parts) with kerosene. Drain oil by blowing with air or absorbing
with shop papers.
–Before assembling, apply Nissan power steering fluid to O-rings and seals.
–Replace gaskets and O-rings with new ones. Be careful not to damage any O-rings, oil seals, and gaskets
during assembly.
lIf following part is scratched after disassembly of steering pump, replace applicable part: case, rear body,
side plate, pulley, rotor, vane, or flow control valve
lMark source of fluid leak with a white marker for identification.
lSeals and copper washers must not be reused.

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)
