Tighten mounting bolt and nut in the order shown in the fig-
ure.

• 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:

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

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

CAUTION:

• Avoid damaging the rebro joint boot, protect it with a shop

cloth or equivalent.

Inspection

INFOID:0000000005249168

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-125, "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.
