A bump shouldn't have caused any problem. The best way would be to raise the rear on stands and runit to see what's going on.

Sure it the rear diff and it's not something like an exhaust / heatshield / baffle plate rattle ?

I hit bumps in the road everyday. Thank you Canada and your frost heaved roads!!!

...it could even be a wheel bearing. 66K is when they start to go. However rear wheel bearings generally last longer than the front.

Or, your spare tire was stuck a bit thanks to the heat/thaws and has lost some air and needs to be refilled and tightened.
