• If the tooth contact is near the face (face contact), or near the
heal (heel contact), thin the pinion sleeve shims to move the
drive pinion closer to the drive gear.
• If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thicken the pinion sleeve shims to move the
drive pinion farther from the drive gear.
PINION BEARING PRELOAD
1.
Remove the pinion sleeve assembly. Refer to
.
2.
Rotate the companion flange back and forth 2 to 3 times. Check for unusual noise, rotation malfunction,
and other malfunctions.
3.
Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

DRIVE PINION
4.
Measure the drive pinion bearing preload with the preload
gauge (A) [SST: ST3127S000 (J-25765-A)].
CAUTION:
• Every rotational part shall rotate smoothly with the speci-
fied gear oil.
• Preload torque differs before disassembly and after reas-
sembly.
• If measured value is out of the specification, disassemble the pin-
ion sleeve assembly to check and adjust each part.
TOTAL PRELOAD
1.
Measure pinion bearing preload torque (P
1
). Refer to
.
2.
Install the pinion sleeve shims and pinion sleeve assembly.
3.
Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
4.
Measure the total preload with the preload gauge (A) [SST:
ST3127S000 (J-25765-A)].
CAUTION:
Preload torque differs before disassembly and after reas-
sembly.
• If measured value is out of the specification, disassemble it to
check and adjust each part. When measuring the total preload
torque after the disassembly, measure it with the transfer case oil seals and gear ring oil seals removed,
then install the oil seals.
COMPANION FLANGE RUNOUT
1.
Fit a dial indicator 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.
While changing the phase between companion flange and drive pinion gear by 90
°
at a time, check runout
and determine which phase angle minimizes the runout.
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 is out of the specification after replacement of companion flange, adjust the assembly status
of the pinion bearings and drive pinion gear, or replace the pinion bearings.

NOISE
• Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
• If center bearing is noisy or damaged, replace propeller shaft assembly.
VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1.
With a dial indicator, measure propeller shaft runout at runout
measuring points by rotating final drive companion flange with
hands.
2.
If runout still exceeds specifications, separate propeller shaft at
final drive companion flange or transfer companion flange; then
rotate companion flange 90, 180, 270 degrees and install pro-
peller shaft.
3.
Check runout again. If runout still exceeds specifications, replace propeller shaft assembly.
4.
Check the vibration by driving vehicle.

Remove propeller shaft assembly.
CAUTION:
If constant velocity joint was bent during propeller shaft
assembly removal, installation, or transportation, its boot may be damaged. Wrap boot interfer-
ence area to metal part with shop cloth or rubber to protect boot from breakage.
7.
Remove clips and center bearing mounting bracket (upper/lower).
INSTALLATION
Note the following, and install in the reverse order of removal.
• Install center bearing mounting bracket (upper) (1) with its arrow
mark (A) facing forward.
• Adjust position of center bearing mounting bracket (upper), center
bearing mounting bracket (lower) (2) sliding back and forth to pre-
vent play in thrust direction of center bearing insulator (3). Install
center bearing mounting bracket (upper/lower) to vehicle.
• Align matching marks to install propeller shaft assembly to final
drive and transfer companion flanges.
• After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 90, 180, 270
degrees. Then perform driving test and check propeller shaft vibra-
tion again at each point.
• After tightening the bolts and nuts to the specified torque, check
that the bolts (3) on the flange side is tightened as shown in the fig-
ure.
• If propeller shaft assembly or final drive assembly has been replaced, connect them as follows:

- Install propeller shaft (1) while aligning its matching mark (A) with
the matching mark (B) of the final drive (2) on the joint as close as
possible.
- Tighten mounting bolts and nuts of propeller shaft and final drive to
the specified torque.

APPEARANCE
Check propeller shaft for bend and damage. If damage is detected, replace propeller shaft assembly.
PROPELLER SHAFT RUNOUT
Check propeller shaft runout at measuring points with a dial indica-
tor. If runout exceeds specifications, replace propeller shaft assem-
bly. For measuring point, refer to
JOURNAL AXIAL PLAY
As shown in the figure, while fixing yoke on one side, check axial
play of joint. If it is outside the standard, replace propeller shaft
assembly.
CAUTION:
Never disassemble joints.
CENTER BEARING
Check center bearing for noise and damage. If noise or damage is detected, replace propeller shaft assembly.
CAUTION:
Never disassemble center bearing.
