2002 Subaru Outback Car Vibrations Recommendations

This past weekend I unfortunately slid my outback off an icy road, over a 2 foot sloped embankment into a field. I was alright and I was able to drive the outback out of the field and it appeared to be running well.

However as I picked up speed (roughly 55 m/h) I began to notice a vibration going through the entire car (steering wheel, headrests, etc). It only begins to happen at around 55 m/h and increases as I go faster.

What are some of your suggestions for the steps I should take to resolve this vibration?

Should I get the tires re-balanced or get the axles / other drive train components taken a look at?

Thanks in advance!
