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 (1, 2) sliding
back and forth to prevent play in thrust direction of center bearing
insulator (3). Install bracket 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.

• Check propeller shaft runout at measuring points. If runout
exceeds specifications, replace propeller shaft assembly. For mea-
suring point, refer to
JOURNAL AXIAL PLAY
• As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft assem-
bly.
