6.

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

CAUTION:

Tighten mounting nuts temporarily.

7.

Remove propeller shaft fixing bolts and nuts.

8.

Remove center bearing mounting bracket fixing nuts.

9.

Remove propeller shaft.

CAUTION:

If constant velocity joint was bent during propeller shaft
assembly removal, installation, or transportation, its boot
may be damaged. Wrap boot interference area to metal part
with shop cloth or rubber to protect boot from breakage.

INSPECTION

●

Inspect propeller shaft runout at measuring points. If runout
exceeds specifications, replace propeller shaft assembly.

●

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

CAUTION:

Do not disassemble joints.

●

Check center bearing for noise and damage. If noise or damage
is detected, replace propeller shaft assembly.

CAUTION:

Do not disassemble 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 transmission companion flanges, and then
tighten to specified torque. Refer to 

PR-5, "Components"

 .

●

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:

1.

Install the propeller shaft while aligning its matching mark A with
the matching mark B on the joint as close as possible.

2.

Tighten the joint bolts to the specified torque. Refer to 

PR-5,

"Components"

 .

CAUTION:

Do not reuse the bolts, nut and washers.
