If the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.
Refer to FFD-36, "
Pinion Height Adjusting Washer" .
If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.
Refer to FFD-36, "
Pinion Height Adjusting Washer" .
Backlash
1. Remove carrier cover. Refer to FFD-20, "Differential Assembly" .
2. Fit a dial indicator to the drive gear face to measure the back-
lash.
If the backlash is outside of the specified value, change the
thickness of side bearing adjusting washer.
Companion Flange Runout
1. Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate companion flange to check for runout.
3. Fit a test indicator to the inner side of companion flange (socket
diameter).
4. Rotate companion flange to check for runout.
5. 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.

Backlash: 0.10 - 0.15 mm (0.0039 - 0.0059 in)
When the backlash is large:
Decrease side bearing adjusting washer thickness.
Refer to FFD-36, "
Side Bearing Adjusting Washer" .
When the backlash is small:
Increase side bearing adjusting washer thickness.
Refer to FFD-36, "
Side Bearing Adjusting Washer" .

Tow Truck TowingNAS00081
CAUTION:
All applicable state or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.
It is necessary to use proper towing equipment to avoid possible damage to the vehicle during
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.
Always attach safety chains before towing.
When towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.
Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI recommends that vehicle be towed with the driving (rear) wheels off the ground or that a dolly be
used as illustrated.
CAUTION:
Never tow automatic transmission models with the rear wheels on the ground or four wheels on
the ground (forward or backward), as this may cause serious and expensive damage to the trans-
mission.
If it is necessary to tow the vehicle with the front wheels raised, always use towing dollies under
the rear wheels.
When towing rear wheel drive models with the front wheels on the ground or on towing dollies:
–Turn the ignition key to the OFF position, and secure the steering wheel in a straight ahead posi-
tion with a rope or similar device.Never secure the steering wheel by turning the ignition key to the
LOCK position. This may damage the steering lock mechanism.
–Move the selector lever to the N (Neutral) position.
When the battery of vehicle equipped with the Intelligent Key system is discharged, your vehicle
should be towed with the front wheels on towing dollies or place the vehicle on a flat bed truck.
If the speed or distance must necessarily be greater, remove the propeller shaft before towing to prevent dam-
age to the transmission.
