Content Conditions and Measures
Hypoid gear

If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.

If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new
drive gear and drive pinion as a set.
Bearing

If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear

If any cracks or damage on the surface of the tooth is found, replace.

If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer

If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal

Whenever disassembled, replace.

If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace
them.
Differential case

If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange

If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the
companion flange is found, replace.

RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and Lubricants NLS00060
*1: For further details, see “SAE Viscosity Number”.
*2: Using automatic transmission fluid 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 INFINITI new
vehicle limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F).
*4: DEXRON
TM III/ MERCONTM or equivalent may also be used. Outside the continental United States and Alaska contact an INFINITI
dealer for more information regarding suitable fluids, including recommended brand(s) of DEXRON TM III/ MERCONTM automatic trans-
mission fluid.
*5: For Canada, NISSAN Automatic Transmission Fluid (ATF), DEXRON
TM III/ MERCONTM , or equivalent ATF may also be used.
*6: Available in mainland U.S.A. through your INFINITI dealer. Capacity (Approximate)

2. Check oil level.
Balancing Wheels (Bonding Weight Type)NLS0006T
REMOVAL
1. Remove inner and outer balance weights from the road wheel. CAUTION:
Be careful not to scratch the road wheel during removal.
2. Using releasing agent, remove double-faced adhesive tape from the road wheel. CAUTION:

Be careful not to scratch the road wheel during removal.

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight. Oil grade and Viscosity:
Refer to MA-12, "
