Symptom Chart: Engine-Speed Related Vibrations
NOTE:
When an engine-speed related vibration is present, engine, engine accessory and engine firing calculations should be carried out.
NOTE:
Any assembly that is out of balance will only cause a first order vibration, it will not cause a higher order vibration.
NOTE:
Some powertrain-speed related vibrations are normal though they should not be felt in the passenger compartment.
