Need Help Identifying Rear Axle Issue.

[DetroitSVT]

I think my rear axles may be bent. I didn't hit anything, but I've noticed the wheels and brake rotors have had a slight wobble after I bought the car and I think it may be getting worse. I took the brake caliper off and setup a dial indicator on the axle. (SEE VIDEO LINK BELOW) The run-out seems pretty bad. Both sides are about the same, so I don't know if the axles are bent or if there is something wrong with the differential.

Any help would be greatly appreciated!
