Driveline vibration after rear tire gouge

[Tony_SS]

On the way to get my exhaust done, I was just thinking to myself - the car is sooo nice and smooth doing 65 down the road.

When I pulled out of the shop, there is a steep curb, my rear tire caught my fender and bent it, and gouged the tire.

On the way home I noticed a vibration around 60mph. It fells like its from the rear of the car.. not in the steering wheel or anything.

My guess is I bent an axle. What does everyone think?

Here's a pic of the fender damage. It also took a good gash out of the tire... I had the tire balanced and it's still the same.

Could this bind have 'sprung' my driveshaft or bent a u-joint?
