I have had my share of vibration issues and causes. This one can be felt immediately after takeoff mainly in the cabin. Tires are new, fresh transmission fluid, like at 4-5 MPH you get this weird vibration inside the cabin and in seat, not in steering. Since the motors in these cars are placed the way, they are, it is easy to see the mounts and axles from too. None looked bad but when I checked the wheel passenger side axle there was an up down movement, none on the driver's side.

Yep, this happens when the center support bearing goes out, here are the instructions on how to remove the rear driveline and change the bearing out. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

They should just pull apart on the splines. Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
