Vibration Diagnostic Aids - Vibration Duplicated, Difficult to Isolate/Balance Component: Notes
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. This type of a condition is usually related to and sensitive to torque-load. The most likely system that could exhibit this type of a condition is the driveline.
