Vibration starts over 35mph???

If it's full vacuum, you're engine breaking, and it could be due to the weight shift. Just a thought.

Vacuum as in my foot is off the gas while my car is in gear, primarily 4th and 5th.

That's when I first noticed my front passenger wheel bearing causing vibrations, but if it's doing it as low as 35, there'd be better signs of a bad bearing, like noise. Doesn't hurt to check anyway.

That said, I'd blame something at the front of your car, since that's where the weight is while it's at its worst.
