Diagnosis And Testing - Propeller Shaft: Vibration
WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.
DRIVELINE VIBRATION
| Drive Condition | Possible Cause | Correction |
|---|---|---|
| Propeller Shaft Noise | 1) Undercoating or other foreign material on shaft. | 1) Clean exterior of shaft and wash with solvent. |
| 2) Loose or bent U-joint yoke or excessive runout. | 2) Install new yoke. | |
| 3) Worn CV/U-joint. | 3) Install new propeller shaft. | |
| 4) Propeller shaft damaged or out of balance. | 4) Install new propeller shaft. | |
| 5) Broken rear spring. | 5) Install new rear spring. | |
| 6) Excessive runout or unbalanced condition. | 6) Re-index propeller shaft, test, and evaluate. | |
| 7) Excessive drive pinion gear shaft runout. | 7) Re-index propeller shaft and evaluate. | |
| Joint Noise | 1) Loose CV/U-joint flange screws. | 1) Install new screws and tighten to proper torque. |
| 2) Lack of lubrication. | 2) Install new propeller shaft/repair joint. |
Tires that are out-of-round, or wheels that are not balanced, will cause a low frequency vibration.
Brake rotors that are unbalanced will cause a harsh, low frequency vibration.
Driveline vibration can also result from loose or damaged engine mounts.
Propeller shaft vibration increases as the vehicle speed is increased. A vibration that occurs within a specific speed range is not usually caused by a propeller shaft being unbalanced. Defective universal joints, or an incorrect propeller shaft angle, are usually the cause of such a vibration.
