How would you test for a first order vibration?
What will be an ideal response?
To test for a first order vibration, raise the vehicle in the air and run the engine in gear to check the driveline. Move the vibration analyzer pickup to different places and try to determine where the energy from the vibration is located. If there is no vibration without a load on the tires, this is not a balance problem and is probably related to misalignment of parts.
