On-Vehicle InspectionINFOID:0000000001327469
APPEARANCE AND NOISE INSPECTION
 Check the propeller shaft tube surface for dents or cr acks. 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 InstallationINFOID: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 jo int 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 prop eller 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.

REAR PROPELLER SHAFT
 Inspect propeller shaft runout at measuring points. If runoutexceeds 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: Propeller shaft runout limit : 0.8 mm (0.031 in)
