PROPELLER SHAFT RUNOUT INSPECTION
If vibration occurs during driving at high speed, check for propeller shaft runout first.
1. Lift vehicle.
2. While rotating final drive companion flange by hand, measure
propeller shaft runout at 4 to 5 points.
Propeller Shaft Runout Measuring Points
Propeller Shaft Runout Adjustment
1. Reinstall companion flange after rotating it by 90°, 180°, and 270°. Then perform driving test and check
propeller shaft runout again at each point.
2. If it still exceeds the limit, replace propeller shaft assembly.
3. Perform driving test to check.
APPEARANCE AND NOISE INSPECTION
●Check propeller shaft tube for dent and cracks on the surface. If necessary, replace propeller shaft
assembly.
●If center bearing has abnormal noise or damage, replace propeller shaft assembly. Runout repair limit : 0.6 mm (0.024 in) or less

Removal and InstallationEDS000ZX
REMOVAL
1. Put mating marks onto propeller shaft flange yoke and final drive and transfer companion flanges.
CAUTION:
Use paint to avoid scratching the surface.
2. Remove mounting nuts and remove exhaust tube insulator from vehicle.
3. Loosen mounting nuts of center bearing mount brackets.
CAUTION:
Tighten nuts temporarily.
4. Remove mounting nuts and bolts from propeller shaft companion flanges, transfer, and final drive.
Remove mounting nuts securing center bearing brackets onto vehicle. Then remove propeller shaft from
vehicle.
CAUTION:
If constant velocity joint was bent during propeller shaft assembly removal, installation, or trans-
portation, its boot may be damaged. Wrap boot interference area to metal part with shop cloth or
rubber to protect boot from breakage.
INSPECTION AFTER REMOVAL
1. As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
2. Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
3. Check center bearing for abnormal noise and damage. If noise
or damage is detected, replace propeller shaft assembly.
CAUTION:
● Center bearings (front and rear) cannot be disassem-
bled.
● Joints cannot be disassembled.

INSTALLATION
Paying attention to following items, install in the reverse order of removal.
●Align mating marks to install propeller shaft, and tighten to specified torque.
● Adjust location of mounting bracket back and forth to prevent
longitudinal give of insulator as shown. Install bracket to vehicle.
●After assembly, perform a driving test to check propeller shaft for
runout. If a runout is detected, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 90°, 180°,
and 270°. Then perform driving test and check propeller shaft
runout again at each point.

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.
