Mystery vibration

What was the last thing done to the Jeep before the noise started?

Hey when you diagnose the issue keep me posted. Very interested..

It almost sounds like the audio lags behind the video based on the timing of when you accelerated. And if that's the case, maybe it's your speedo wheel or the sender on the plastic housing. Seems to be about the right frequency. Do you have an SYE?
