4.

Put matching marks (A) on propeller shaft rubber coupling and
final drive companion flange.

CAUTION:

For matching marks, use paint. Never damage propeller
shaft rubber coupling and final drive companion flange. 

5.

Loosen mounting nuts (1) of center bearing mounting brackets
(upper/lower).

CAUTION:

Tighten mounting nuts temporarily.

6.

Remove propeller shaft assembly fixing bolts and nuts (

).

CAUTION:

Never remove the rubber coupling from the propeller shaft
assembly.

7.

Slightly separate the rubber coupling (1) from the final drive
companion flange (2).

CAUTION:

Never damage the final drive companion flange and rubber
coupling.

8.

Remove center bearing mounting bracket fixing nuts.

CAUTION:

• The angle (A) is third axis rubber coupling (1) forms with

the final drive companion flange (2). Never bend rubber
coupling above the angle (A).

• Never damage the grease seal (3).
• Never damage the rubber coupling.

9.

Slide the propeller shaft in the vehicle forward direction slightly. Separate the propeller shaft from the final
drive companion flange.

CAUTION:

• Never damage the grease seal.
• Never damage the rubber coupling.

10. Remove the propeller shaft assembly from the vehicle.

CAUTION:

Never damage the rear oil seal of transmission.

11. Remove clip 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 rubber coupling to

final drive companion flange.

• 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 120, 240
degrees. Then perform driving test and check propeller shaft vibra-
tion again at each point.

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

follows:

- Install the propeller shaft (1) while aligning its matching mark (A)

with the matching mark (B) on the joint as close as possible.

Inspection

INFOID:0000000005249159

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 

DLN-117, "Inspection"

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.
