Check your u joints on the rear driveshaft. Also check for play in the front driveshaft, its cv is notorious for going out.

If it is your FDS, take it to a driveline shop and have them cut the companion joint off and put a U-joint on. I know 3 people that have done it including myself.

More than likely front driveshaft
Get a front replacement shaft
don't cut and slice

I cgot my cut and sliced almost 6 months ago with not one single issue. No vibration. No nothing. I would recommend it, some obviously won't.
