b.
Using thickness gauges, measure the clearance between side
gear back and differential case at 3 different positions, while
rotating side gear. Average the 3 readings, and then measure
the clearance. (Measure the clearance of the other side as well.)
CAUTION:
To prevent side gear from tilting, insert thickness gauges
with the same thickness from both sides.
c.
If the back clearance is outside the specification, use a thicker/
thinner side gear thrust washer to adjust. Refer to
.
CAUTION:
Select a side gear thrust washer for right and left individu-
ally.
6.
Drive a lock pin into pinion mating shaft, using the pin punch.
CAUTION:
Do not reuse lock pin.
7.
Press side bearing inner races to differential case, using the
drift.
CAUTION:
Do not reuse side bearing inner race.
8.
Apply thread locking sealant into the thread hole of drive gear.
●
Use Genuine Medium Strength Thread Locking Sealant or
equivalent. Refer to
CAUTION:
The drive gear back and threaded holes shall be cleaned
and decreased sufficiently.
Side gear back clearance specification:
0.2 mm (0.008 in) or less.
(Each gear should rotate smoothly without excessive
resistance during differential motion.)
When the back clearance is large:
Use a thicker thrust washer.
When the back clearance is small:
Use a thinner thrust washer.

9.
Install drive gear to the differential case, and apply anti-corrosive
oil onto threads and seats on the mounting bolts, and then
tighten to the specified torque. Refer to
10. Apply gear oil to side bearings, and install new side bearing
adjusting shims (2 pieces for one side) with the same thickness
as the ones installed prior to disassembly or re-install the old
ones, with side bearing outer race to differential case.
If side bearing adjusting shims have been already selected, use
them.
CAUTION:
Do not reuse side bearing outer race.
11. Set the drifts to the right and left side bearing adjusting shims
individually. Compress differential case assembly and side bear-
ing to install gear carrier assembly to differential case assembly.
CAUTION:
●
The drift shall be placed on the center of the adjusting
shims.
●
The pressure shall be as low as possible to install differ-
ential assembly into gear carrier assembly. The maximum
pressure shall be 10 kN (1 ton, 1.1 US ton, 1.0 Imp ton).
●
If the adjusting shims are installed by tapping, the gear
carrier may be damaged. Avoid tapping.
12. Install dummy cover set, check and adjust drive gear runout, tooth contact, backlash, and total preload
torque. Refer to
,
13. Remove dummy cover set.
14. Apply liquid gasket to mating surface of rear cover. Overlap both
ends of the bead for at least 3 mm (0.12 in).
●
Use Genuine Silicone RTV or equivalent. Refer to
"RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS"
.
CAUTION:
Remove old sealant adhering to the mounting surfaces.
Also remove any moisture, oil, or foreign material adhering
to the mounting surfaces.
15. Set the drifts to the right and left side bearing adjusting shims
individually. Compress differential case assembly and side bear-
ing to install rear cover.
CAUTION:
●
The drift shall be placed on the center of the adjusting
shims.
●
The pressure shall be as low as possible to install the
rear cover. The maximum pressure shall be 10 kN (1 ton,
1.1 US ton, 1.0 Imp ton).
●
If rear cover is forced in by tapping, rear cover may be
damaged by adjusting shims. Avoid tapping.
16. Tighten rear cover mounting bolts to the specified torque. Refer to

PRECAUTIONS
PFP:00001
Cautions
NES0008L
●
When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on level ground. Oil will 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.
●
Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

On-Vehicle Inspection
NES0008P
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
●
Measure axial end play of the suspension arm ball joint by prying between the suspension arm and axle
with a iron bar or something similar.
CAUTION:
Be careful not to damage ball joint boot.
SHOCK ABSORBER INSPECTION
●
Check shock absorber for oil leakage, damage and replace if necessary.
Wheel Alignment Inspection
NES0008Q
DESCRIPTION
●
Measure wheel alignment under unladen conditions. “Unladen conditions” mean that fuel, engine coolant,
and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.
PRELIMINARY CHECK
●
Check tires for improper air pressure and wear.
●
Check road wheels for runout.
●
Check wheel bearing axial end play.
●
Check suspension arm ball joint axial end play.
●
Check shock absorber operation.
●
Check each mounting point of axle and suspension for looseness and deformation.
●
Check each link, arm and member for cracks, deformation, and other damage.
●
Check vehicle posture.
GENERAL INFORMATION AND RECOMMENDATIONS
●
A four-wheel thrust alignment should be performed.
–
This type of alignment is recommended for any NISSAN/INFINITI vehicle.
–
The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is
centered.
–
The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
–
The rack should be checked to ensure that it is level.
●
Make sure the machine is properly calibrated.
–
Your alignment equipment should be regularly calibrated in order to give correct information.
–
Check with the manufacturer of your specific equipment for their recommended Service/Calibration
Schedule.

REAR SUSPENSION ASSEMBLY
Revision: 2006 August

THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specifications listed in this Service Manual.
●
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 machine that operate these indicators may not be cor-
rect.
–
This may result in an ERROR.
●
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're using for more information on this.
CAMBER INSPECTION
●
Measure camber of both right and left wheels with a suitable
alignment gauge and adjust in accordance with the following
procedures.
If outside the standard value, adjust with adjusting bolt on front
lower link.
NOTE:
After adjusting camber, be sure to check toe-in.
TOE-IN
If toe-in is not within the specification, adjust with adjusting bolt in
rear lower link.
CAUTION:
Be sure to adjust equally on RH and LH side with adjusting bolt.
If toe-in is not still within the specification, inspect and replace any
damaged or worn rear suspension parts.
