NISSAN does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
When towing with the front wheels on the ground or rear
wheels on the ground (If you do not use towing dollies): Set
the free-running hubs to the free position and move the
transfer case shift lever into the “2H” position.
When towing with the front on the ground: Turn the ignition
key to the OFF position and secure the steering wheel in a
straight ahead position with a rope or similar device. Never
place the ignition key in the LOCK position. This will result
in damage to the steering lock mechanism.
Towing Point
CAUTION:
Never tow the vehicle using only the towing points. To avoid
damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a stuck vehicle)EAS001FZ
Tow chains or cables must be attached only to the main structural members of the vehicle or the
towing hooks (if so equipped). Otherwise, the vehicle body will be damaged.
Use the towing hook (if so equipped) only to free a vehicle stuck in sand, snow, mud, etc. Never
tow the vehicle for a long distance using only the towing hook.
The towing hook is under tremendous force when used to free a stuck vehicle. Never pull the hook
at an angle.
Always pull the cable straight out from the front or rear of the vehicle.
Pulling devices should be routed so they do not touch any part of the suspension, steering, brake,
or cooling systems.
Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
WA RN ING:
Stand clear of a stuck vehicle.
Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.

Balancing WheelsELS001H4
REMOVAL
1. Using releasing agent, remove double-faced adhesive tape from the wheel.
CAUTION:
Be careful not to scratch the wheel during removal.
After removing double-faced adhesive tape, wipe clean traces of releasing agent from the
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 wheels.
1. Set wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer imbalance values are shown on the wheel balancer indicator, multiply outer imbal-
ance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value and install it to the designated outer position of, or at the desig-
nated angle in relation to the road wheel.
CAUTION:
Do not install the inner balance weight before installing the outer balance weight.
Before installing the balance weight, be sure to clean the mating surface of the wheel.
Indicated imbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 g = 35 g (1.23 oz)
37.5 g = 40 g (1.41 oz)Drain plug : Refer to FFD-13, "
COMPONENTS" (FFD), RFD-12, "Components"

Rear Wheel Alignment Adjusting Bolts
PRELIMINARY INSPECTION
WA RN ING:
Always adjust the alignment with the vehicle on a flat surface. Use CONSULT-II "EXHAUST SOLE-
NOID" active test to release the air pressure from the rear load leveling air suspension system.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for runout and damage. Refer to WT-5, "
Inspection" .
4. Check the wheel bearing axial end play.
5. Check the shock absorbers. Refer to RSU-26, "
SHOCK ABSORBER INSPECTION" .
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer to RSU-48, "
Wheelarch Height (Unladen*1 )" .
If vehicle height is not within ± 10 mm (0.39 in) of the specification, perform the control unit initialization
procedure. Refer to RSU-46, "
Initialization Procedure" .
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
This type of alignment is recommended for any NISSAN vehicle.
The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
The alignment machine itself should be capable of accepting any NISSAN vehicle.
The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated.
Your alignment machine should be regularly calibrated in order to give correct information.

REAR SUSPENSION ASSEMBLY
Revision: October 20052005 QX56
Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-47, "Wheel
Alignment"
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
See Instructions in the alignment machine you are using for more information.
CAMBER
1. Measure camber of both the right and left wheels with a suitable
alignment gauge and adjust as necessary to specification.
2. If outside of the specified value, adjust the camber using the
adjusting bolt in the front lower link.
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 0° 5' with each graduation of the adjust-
ing bolt.
3. Tighten the adjusting bolt nuts to specification.
TOE-IN
1. Bounce the rear of the vehicle up and down two to three times to stabilize the vehicle height. Refer to
RSU-48, "
Wheelarch Height (Unladen*1 )" .
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on the base line of the tread (rear side) of both of the
tires at the same height as the center of the hub. This will be the
measuring points.
4. Measure the distance “A” (rear side) across from tire to tire.Camber : Refer to RSU-47, "
Wheel Alignment" .
