Vibes: Damaging t-case output bearing or pinion bearing

I hit my driveshaft on some rocks several months ago and have had vibes ever since. I finally got around to getting the driveshaft fixed and balanced, and the vibes are less now, but they're still there, and they weren't there at all before I originally hit the driveshaft. I just balanced the tires to make sure that wasn't it. What are the odds the transfer case output bearing or the pinion bearing is shot? Anything else I should check? How do you check those things to make sure they're ok? I haven't been able to notice any play when trying to turn them by hand and there is no driveline hum.

Edit: I've tested it without the front driveshaft and that is not the cause of the vibrations. It does add to it, but it's not causing the major vibes.
