On-Vehicle Inspection

INFOID:0000000001327469

APPEARANCE AND NOISE INSPECTION

• Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
• If center bearing is noisy or damaged, replace center bearing.

PROPELLER SHAFT VIBRATION

If vibration is present at high speed, inspect propeller shaft runout first.
1.

Measure propeller shaft runout at runout measuring points by
rotating final drive companion flange with hands. For measuring
point, refer to 

PR-4, "On-Vehicle Inspection"

.

2.

If runout still exceeds specifications, separate propeller shaft at
final drive companion flange; then rotate companion flange 60,
120, 180, 240, 300 degrees and install propeller shaft.

3.

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

4.

Check the vibration by driving vehicle.

Removal and Installation

INFOID:0000000001327471

REMOVAL

1.

Move the A/T select lever to N position and release the parking brake.

2.

Remove the tunnel stay with power tool. Refer to 

RSU-5

.

3.

Remove the center muffler with power tool. Refer to 

EX-3

.

4.

Loosen mounting nuts of center bearing mounting brackets with
power tool.

CAUTION:

Tighten mounting nuts temporarily.

5.

For 2WD models
• Put matching marks on propeller shaft rebro joint with final

drive companion flange.

CAUTION:

For matching mark, use paint. Never damage propeller
shaft and companion flange. 

For AWD models
• Put matching marks on propeller shaft flange yoke with trans-

fer companion flange and on rebro joint with final drive com-
panion flange.

CAUTION:

For matching mark, use paint. Never damage propeller
shaft flange yoke, rebro joint and companion flanges. 

6.

Remove propeller shaft fixing bolts and nuts.

7.

Remove center bearing mounting bracket fixing nuts.

8.

Remove propeller shaft.

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.

< SERVICE INFORMATION >

REAR PROPELLER SHAFT

• Inspect propeller shaft runout at measuring points. If runout

exceeds specifications, replace propeller shaft assembly. For mea-
suring point, refer to 

PR-4, "On-Vehicle Inspection"

.

• As shown in the figure, while fixing yoke on one side, check axial

play of joint. If outside the standard, replace relevant propeller
shaft.

• Check propeller shaft for bend and damage. If damage is detected,

replace relevant propeller shaft.

CAUTION:

Never disassemble joints.

• Check center bearing for noise and damage. If noise or damage is

detected, replace center bearing. Refer to 

PR-11, "Disassembly

and Assembly of Center Bearing"

.

INSTALLATION

Note the following, and install in the reverse order of removal.

CAUTION:

Avoid damaging the rebro joint boot, protect it with a shop towel or equivalent.
• Align matching marks to install propeller shaft to final drive and transfer (AWD models only) companion

flanges, and then tighten to specified torque. Refer to 

PR-8, "Component"

.

• Install center bearing mounting bracket (Upper) with its arrow mark

facing forward.

• Adjust position of mounting bracket sliding back and forth to pre-

vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.

• 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 60, 120, 180,
240, 300 degrees. Then perform driving test and check propeller
shaft vibration again at each point.

• If propeller shaft or final drive has been replaced, connect them as follows:
