APPEARANCE AND NOISE INSPECTION
lCheck the propeller shaft tube surface for dents or cracks. If damaged, replace the propeller shaft assem-
bly.
lCheck the bearings for noise and damage. Repair or replace the bearings as necessary.
PROPELLER SHAFT VIBRATION
If a vibration is present at high speed, inspect the propeller shaft runout first.
1. Measure the runout of the propeller shaft tube at several points
by rotating the final drive companion flange with your hands.
For measuring point, refer toPR-7, "
Propeller Shaft Runout
Measuring Point".
2. If the runout exceeds specifications, disconnect the propeller
shaft at the final drive companion flange; then rotate the com-
panion flange 90°,180°and 270°and reconnect the propeller
shaft.
3. Check the runout again. If the runout still exceeds specifications, replace the propeller shaft assembly.
4. After installation, check for vibration by driving vehicle.
