PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00060
Observe the following precautions when disassembling and servicing drive shaft.
lPerform work in a location which is as dust-free and dirt-free as possible.
lBefore disassembling and servicing, clean the outside of parts.
lThe disassembly and service location must be clean. Care must be taken to prevent parts from becoming
dirty and to prevent the entry of foreign objects.
lDisassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.
lPaper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.
lDisassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
Precautions for Brake SystemEDS0 00 I2
lWhen 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.
lUse flare nut wrench when removing or installing brake tubes.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lAlways torque brake lines when installing.

CautionEDS00056
lBefore starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic oper-
ations.
lCheck 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.
lCarry out an overhaul in a clean work place. Using a dust proof room is recommended.
lBefore 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.
lCheck appearance of the disassembled parts for damage, deformation, and abnormal wear. If a malfunc-
tion is detected, replace it with a new one.
lNormally replace lock pins, oil seals, and bearings with new ones every time they are removed.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lClean and flush the parts sufficiently and blow them dry.
lBe careful not to damage the sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or a shop cloth to prevent entering of lint.
lDuring 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.
lDo not reuse drained oil. Discard waste oil after oil changes or part treatment in accordance with local
laws and regulations.
Precautions for Brake SystemEDS000HX
lWhen 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.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lUse flare nut wrench when removing or installing brake tubes.
lAlways torque brake lines when installing.

lFinal tightening of bushings must be carried out under unladen condition with tires on the ground. Oil will
shorten life of bushings. Be sure to wipe off any spilled oil.
l“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
lAfter installing the removed suspension parts, always check wheel alignment and adjust if necessary.
lReplace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

On-Vehicle Inspection and Service
EES0007F
Check axle and suspension parts for excessive play, wear, and damage.
lMove rear wheels (RH/LH) to check abnormal free play.
lRetighten all nuts and bolts to the specified torque.
lCheck strut for oil leakage and damage.
Wheel AlignmentEES0007G
DESCRIPTION
lMeasure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check strut operation.
5. Check each mounting point of axle and suspension for looseness and deformation.
6. Check each link and arm for cracks, deformation, and other damage.
7. Check the vehicle posture.
CAMBER
Camber is preset at factory and cannot be adjusted.
lIf the camber is not within specification, inspect and replace any damaged or worn rear suspension parts.
TOE-IN
Measure toe-in using the following procedure.
lAlways perform following procedure on a flat surface.
lMake sure that no person is in front of the vehicle before push-
ing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tires at the
same height as hub center.this mark is a measuring points.
