PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00101
●Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic oper-
ations.
●Check for the correct installation status prior to removal or disassembly. When mating marks are required,
be sure they do not interfere with the function of the parts they are applied to.
●Carry out an overhaul in a clean work place. Using a dust proof room is recommended.
●Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
●Check appearance of the disassembled parts for damage, deformation, and abnormal wear. If a malfunc-
tion is detected, replace it with a new one.
●Normally replace lock pins, oil seals, and bearings with new ones every time they are removed.
●In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
●Clean and flush the parts sufficiently and blow them dry.
●Be careful not to damage the sliding surfaces and mating surfaces.
●When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
●Always use shop paper for cleaning the inside of components.
●Avoid using cotton gloves or a shop cloth to prevent entering of lint.
●During assembly, observe the specified tightening torque, and apply new differential oil, Vaseline, or Nis-
san MP Special Grease No. 2, as specified for each vehicle, when necessary.
●Do not reuse drained oil. Discard waste oil after oil changes or part treatment in accordance with local
laws and regulations.
Precautions for Brake SystemEDS00102
●When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
●After installing removed suspension parts, check wheel alignment and adjust if necessary.
●Use flare nut wrench when removing or installing brake tubes.
●Always torque brake lines when installing.

OVERALL PRELOAD TORQUE
1. Drain the oil.
2. Remove electronically controlled coupling assembly.
Refer to “Electronically Controlled Coupling Assembly”.
3. Rotate the drive pinion gear back and forth in 2 - 3 times to check for abnormal noise and rotation mal-
function.
4. Rotate the drive pinion gear at least 20 times to check for
smooth operation of the bearing.
5. Fit the drive pinion gear socket onto the drive pinion gear spline.
Using a preload gauge, measure the overall preload torque.
●If outside the standard, disassemble, check, and adjust each
part. Adjust the pinion bearing and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bear-
ing preload.
Side bearing adjusting shims
HYPOID GEAR BACKLASH
1. Drain the oil.
2. Remove the rear cover. Refer to RFD-20, "

COMPANION FLANGE RUNOUT
1. Fit a dial gauge onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate the companion flange to check for runout.
3. Fit a test indicator to the inner side of the companion flange
(socket diameter).
4. Rotate the companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion gear by 90° step,
and search for the point where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c. If the runout value is still outside of the limit after the companion flange has been replaced, possible cause
will be an assembly malfunction of the drive pinion gear and the electronically controlled coupling, mal-
functioning coupling bearing, or malfunctioning electronically controlled coupling.
TOOTH CONTACT
1. Drain the oil.
2. Remove the rear cover. Refer to RFD-20, "
Removal of Differen-
tial Assembly"

BACKLASH" .
4. Apply red lead to drive gear face.
CAUTION:
Apply red lead to the both faces of 3 to 4 gears at 4 loca-
tions evenly spaced on the drive gear.
5. Rotate the drive gear back and forth in several times, check
drive pinion gear to drive gear tooth contact.
CAUTION:
Check tooth contact on drive side (acceleration) and
reverse side (deceleration).Runout limit : 0.13 mm (0.0051 in)

pinion.
CAUTION:
Do not reuse the pinion rear bearing inner race.
4. After checking and adjusting the tooth contact and backlash of
the hypoid gear following the procedure below, assemble a col-
lapsible spacer to the drive pinion.
CAUTION:
●Be careful of the mounting orientation of the collapsible
spacer.
●Do not reuse the collapsible spacer.
a. Apply differential oil to the pinion bearing, and assemble the
drive pinion to the carrier case.
CAUTION:
Do not assemble a collapsible spacer.
b. Assemble a pinion front bearing inner race to the drive pinion.
Using a drift and press stand, press the pinion nut as far as it
can be tightened.
c. Temporarily tighten the removed pinion nut to the drive pinion.
NOTE:
