Put the back up in the air with stands under the axle, as close to the tires as you can, block the front wheels, and start it. Put it in first, and let it go. The idle will keep it running. If it doesn't start shaking, take a look and listen, and see what you can find. If it does start to "shake", something is seriously out of balance, and you need to have it looked at.
Take care,
