Check the propeller shaft tube surface for dents or cr acks. If damaged, replace propeller shaft assembly.
VIBRATION
If vibration is present at high speed, inspect propeller shaft runout
first.
1. With a dial indicator, measure propeller shaft runout at runout measuring points by rotating final drive companion flange with
hands.
2. If runout still exceeds specifications, separate propeller shaft at final drive companion flange; then rotate companion flange 90, 180, 270 degrees and install propeller
shaft.
3. Check runout again. If runout still exceeds spec ifications, replace propeller shaft assembly.
4. Check the vibration by driving vehicle.
RUNOUT MEASURING POINT
Propeller shaft runout measuring point (Point “ ”).

REMOVAL
1. Shift the transmission to the neutral pos ition, and then release the parking brake.
2. Put matching mark (A) on rear propeller shaft flange yoke and rear drive companion flange.
CAUTION:
For matching mark, use paint. Never damage propeller shaft
flange and final drive companion flange.
3. Put matching mark (A) on rear propeller shaft flange yoke and transfer companion flange.
CAUTION:
For matching mark, use paint. Never damage propeller shaft
flange and transfer companion flange.
4. Remove the propeller shaft assembly fixing bolts.
5. Remove propeller shaft assembly from the rear final drive and transfer.
6. Perform inspection after removal. Refer to DLN-146, "
Inspection".
INSTALLATION
Note the following, and install in the reverse order of removal.
Align matching mark (A) to install propeller shaft flange yoke and
transfer companion flange.
Align matching mark (A) to install propeller shaft flange yoke and
rear 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 90, 180, 270
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 while aligning its matching mark (A) with
the matching mark (B) on the joint as close as possible.

1. Put a matching mark between propeller shaft and flange yoke
and remove snap rings (1).
CAUTION:
For matching mark, use paint. Never damage the surface.
2. Lightly tap bottom of yoke using a copper hammer and remove journal bearing.
CAUTION:
Never damage the yoke.
3. Remove grease nipple.
ASSEMBLY
1. Install journal bearing to journal. CAUTION:
Never reuse journal or journal bearing.
Always replace journal, journal b earing, and snap rings as a set.
Apply multi-purpose grease to journal bearing.
2. Install bearing (1) using a vise. CAUTION:
Never damage bearing or flange yoke.
3. Install journal to propeller shaft so that grease nipple (1) on jour- nal portion is in the same direction.
CAUTION:
Never reuse journal.

INSPECTION AFTER REMOVAL
Appearance
Check the propeller shaft for dents or cracks. If damage is detected, replace the propeller shaft assembly.
Propeller Shaft Runout
Check propeller shaft runout at measuring point with a dial indicator.
If runout exceeds specifications, replace propeller shaft assembly.
For measuring point, refer to DLN-142, "
Inspection".
Journal Axial Play
As shown in the figure, while fixing yoke on one side, check axial
play of joint. If axial play exceeds specifications, replace propeller
shaft assembly.
