• 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

Remove the pinion sleeve assembly. Refer to

DLN-62, "Disassembly"

Rotate the companion flange back and forth 2 to 3 times. Check for unusual noise, rotation malfunction,
and other malfunctions.

Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

DRIVE PINION

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

Measure pinion bearing preload torque (P

). Refer to

DLN-76, "Preload Torque"

Install the pinion sleeve shims and pinion sleeve assembly.

Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

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

Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).

Rotate the companion flange to check for runout.

Fit a test indicator to the inner side of the companion flange
(socket diameter).

Rotate the companion flange to check for runout.

If the runout value is outside the repair limit, follow the procedure below to adjust.

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.

If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.

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.

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.

Check runout again. If runout still exceeds specifications, replace propeller shaft assembly.

Check the vibration by driving vehicle.

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.

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:
