If you have not completed the Vibration Analysis tables as indicated and reviewed Vibration Diagnostic Aids, refer to Vibration Diagnostic Aids BEFORE proceeding. |
If you have duplicated the vibration concern but have had difficulty in balancing a component or isolating a component, refer to the following information.
Most vibration concerns are corrected or eliminated through correcting excessive runout of a component, correcting balance of a component or isolating a component which has come into abnormal contact with another object/component.
Components which can generate a lot of energy and are experiencing excessive runout, imbalance or ground-out can produce a vibration with a strong enough amplitude that the vibration can transmit to components which are closely related. Problems of this nature are usually related to and sensitive to the torque load The system most likely to cause this is the powertrain.
