• Measure the outer diameters (“d1”, “d2”) at two positions as shown.
• If reduction appears in places other than “B” range, regard it as
“d
2”.
• If it exceeds the limit (a large difference in dimensions), replace
main bearing cap bolt with a new one.
CONNECTING ROD BOLT OUTER DIAMETER

• If reduction appears in a position other than “d”, regard it as “d”.
• When “d” exceeds the limit (when it becomes thinner), replace
connecting rod bolt with a new one.
CLOGGED OR DAMAGED OIL FILTER (FOR INTAKE VALVE TIMING CONTROL)
• Make sure that there is no foreign material on the oil filter and
check it for clogging.
- Clean it if necessary.
• Check the oil filter for damage.
- Replace it if necessary.
FLYWHEEL DEFLECTION (M/T MODELS)
• Measure the deflection of flywheel contact surface to clutch with a
dial indicator (A).
• Measure the deflection at 210 mm (8.27 in) diameter.
• If measured value is out of the standard, replace flywheel.
• If a trace of burn or discoloration is found on the surface, repair it
with sandpaper.
CAUTION:
When measuring, keep magnetic fields (such as dial indicator
stand) away from signal plate of the rear end of crankshaft.
MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
CAUTION:
Never disassemble double mass flywheel.
Movement Amount of Thrust (Fore-and-Aft) Direction
• Measure the movement amount of thrust (fore-and-aft) direction when 100 N (10.2 kg, 22 lb) force is added
at the portion of 125 mm (4.92 in) radius from the center of flywheel.

7. Pry off drive shaft from transaxle assembly side as shown.
• Make sure that circlip is attached on the edge.
CAUTION:
• Do not apply an excessive angle to drive shaft joint when
removing from the transaxle.
• Do not excessively extend slide joint.
• Do not allow drive shaft to hang down. Support the entire
drive shaft.
INSPECTION AFTER REMOVAL
• Move joint up/down, left/right, and in axial direction. Check for any rough movement or significant looseness.
• Check boot for cracks or other damage, and for grease leakage.
• If damaged, disassemble drive shaft to verify damage, and repair
or replace as necessary.
INSTALLATION
Installation is in the reverse order of removal. Note the following:
• Refer to "COMPONENTS" for tightening torque.
CAUTION:
Do not reuse non-reusable parts.
• In order to prevent damage to differential side oil seal, place Tool
onto oil seal before inserting drive shaft as shown. Slide drive shaft
into slide joint and tap with a hammer to install securely.
• Install new circlip on drive shaft in the circlip groove on transaxle
side. Refer to FAX-12, "
Disassembly and Assembly (Left Side)" .
CAUTION:
Make sure the new circlip on the drive shaft is securely fas-
tened.
• After its insertion, try to pull the flange out of the slide joint by hand.
If it pulls out, the circlip is not properly meshed with the transaxle
side gear.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703715
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001703716
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
CautionsINFOID:0000000001703717
• When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires
on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
• After servicing suspension parts, be sure to check wheel alignment.
• Self-lock nuts are not reusable. Always use new ones when installing.
