Vibration in the Rear End?

I thought I was getting some vibration in the rear end, specifically around 50-60 mph. But playing around trying to replicate the vibration, I noticed it continued to do so with the clutch was disengaged. When the engine speed slowed down, the vibration went away, when I rev it, I can feel it come back.

Anyone have similar issues? I know the engine is mounted pretty rigid, maybe at a certain rev it's transferring through the car a bit? Dunno, but it shakes my rear view mirror!

I think I would report that to the service department. Your testing is pretty spot on and would seem to point to some sort of engine or accessory imbalance. Can you feel it sitting in the driveway and slowly reving the engine up to the same rpm? If so, you can consider removing the accessory belt and repeat the test to see if there is any change. But probably a service visit is going to be required.

I did not try it at an idle. It's actually at the dealer right now getting some fun stuff put on!
