ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.

WAR NING :
Be careful not to burn yourself, as engine oil may be hot.
Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.

Changing A/T FluidNLS00081
1. Warm up ATF.
2. Stop engine.
3. Loosen the level gauge bolt.
4. Drain ATF from drain plug and refill with new ATF. Always refill
same volume with drained ATF.
To replace the ATF, pour in new ATF at the A/T fluid charging
pipe with the engine idling and at the same time drain the old
ATF from the radiator cooler hose return side.
When the color of the ATF coming out is about the same as
the color of the new ATF, the replacement is complete. The
amount of new ATF to use should be 30 to 50% increase of
the stipulated amount.
CAUTION:
Use only Genuine NISSAN Matic J ATF. Do not mix with other ATF.
Using ATF other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and
automatic transmission durability, and may damage the automatic transmission, which is not
covered by the warranty.
When filling ATF, take care not to scatter heat generating parts such as exhaust.
Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to AT- 1 3 , "
Checking A/T Fluid" . If ATF is still dirty, repeat step 2.
through 5.
7. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
8. Tighten the level gauge bolt.
Checking Transfer FluidNLS00082
Check for fluid leakage and fluid level.
(For details, refer to TF-9, "

CHECKING RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the hydraulic pressure gauge [SST] between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer to PS-8, "
Air
Bleeding Hydraulic System" .
2. Start engine. Run engine until oil temperature reaches 50 to
80
C (122 to 176F).
CAUTION:
Leave the valve of the hydraulic pressure gauge [SST]
fully open while starting and running engine. If engine is
started with the valve closed, the hydraulic pressure in
oil pump goes up to the relief pressure along with
unusual increase of oil temperature.
Be sure to keep hose clear of belts and other parts when
engine is started.
3. Fully close the hydraulic pressure gauge [SST] valve with
engine at idle and measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Repair oil pump is the
relief oil pressure is outside the standard. Refer to PS-30, "
Dis-
assembly and Assembly (Models with VK45DE)" , PS-34, "Disassembly and Assembly (Models with
VQ35DE)" .
5. After inspection, disconnect the hydraulic pressure gauge [SST] from hydraulic circuit, then add fluid and
bleed air. Refer to PS-8, "
Air Bleeding Hydraulic System" .

REMOVAL
1. Drain power steering fluid from reservoir tank.
2. Remove undercover from vehicle with a power tool.
3. Loosen drive belt. Refer to EM-15, "
DRIVE BELTS" (VQ35DE), EM-174, "DRIVE BELTS" (VK45DE).
4. Remove drive belt from oil pump pulley.
5. Remove piping of high pressure and low pressure (drain fluid from their pipings). Refer to PS-38,

Companion Flange Runout
1. Fit a test indicator to the inner side of companion flange (socket
diameter).
2. Rotate companion flange to check for runout.
3. If the runout value is outside the runout limit, follow the proce-
dure below to adjust.
a. Check for runout while changing the phase between companion
flange and drive pinion by 90
step, and search for the position
where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has
been changed, possible cause will be an assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if necessary.
c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
DISASSEMBLY
Differential Assembly
1. Drain gear oil, if necessary.
2. Remove side flange.
3. Remove rear cover mounting bolts.
4. Remove rear cover to insert the seal cutter between gear carrier
and rear cover.
CAUTION:
Be careful not to damage the mating surface.
Do not insert flat-bladed screwdriver, this way damage
the mating surface.
5. Using two 45 mm (1.77 in) spacers, mount carrier on the attach-
ment.
6. For proper reinstallation, paint matching marks on one side of
the bearing cap.
CAUTION:
For matching marks, use paint. Do not damage bearing
caps and gear carrier.
Bearing caps are line-board during manufacture. The
matching marks are used to reinstall them in their origi-
nal positions.Runout limit: 0.08 mm (0.0031 in)

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Service Notice or PrecautionsNDS000D5
Do not reuse transfer fluid, once it has been drained.
Check the fluid level or replace the fluid only with the vehicle parked on level ground.
During removal or installation, keep inside of transfer clear of dust or dirt.
Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern.
Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause
longitudinal vibration.
Disassembly should be done in a clean work area, it is preferable to work in dustproof area.
Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.
Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
Gaskets, seals and O-rings should be replaced any time when the transfer is disassembled.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.
Observe the specified torque when assembling.
Clean and flush the parts sufficiently and blow-dry them.
Be careful not to damage sliding surfaces and mating surfaces.
Clean innerparts with lint-free cloth or towels. Do not use cotton work gloves and rags to prevent adhering
fibers.
