Drive/Propeller Shaft: Testing and Inspection
PROPELLER SHAFT VIBRATION
Out-of-round tires or wheels that are out of balance, will cause a low frequency vibration. Driveline vibration can also caused by loose or damaged
engine mounts. Propeller shaft vibration increases with vehicle speed. A vibration that occurs at a specific speed range, is not usually caused by an out
of balance propeller shaft. Defective universal joints or an incorrect propeller shaft angle are usually the cause of such a vibration.

PROPELLER SHAFT BALANCE
If propeller shaft is suspected of being out of balance, use the following procedure.
NOTE: Indexing propeller shaft 180° relative to the yoke may eliminate some vibrations.
1. Raise and support vehicle.
2. Clean all foreign material from the propeller shaft and universal joints.
3. Inspect propeller shaft for missing balance weights, broken welds and bent areas. If propeller shaft is bent, it must be replaced.
4. Inspect universal joints for wear and properly installed.
5. Check propeller shaft bolt torques.
6. Remove wheels and install lug nuts to retain brake rotors.
7. Mark and number the shaft six inches from the pinion yoke end at four positions 90° apart.
8. Run and accelerate vehicle until vibration occurs. Note the intensity and speed the vibration occurred. Stop the engine.
