APPEARANCE AND NOISE INSPECTION

• Check the propeller shaft tube surface for dents or cracks. If damaged, replace the propeller shaft assembly.

• Check 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.

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 the vehicle.
