ok well here are some test results from the test drive:
*makes a grown/howl when turning wheel
*when coasting with foot off gas and in drive- the howling/whirling sound is still there
*when coasting in netural-still makes the howling/whirling sound
*when coasting under 30mph-sound is still there
*get's louder as speed increases
tomorrow i'm gonna swap wheels/tires and see if sound is still there to eliminate wheels/tires as a cause

Since the noise didn't go away when coasting in neutral, I'd bet it's not U joints. They usually make the most noise when under load. Speeding up and slowing down in gear.

I can't remember if i had them balanced when i had the tires mounted but i wanna say that they weren't because the guy said that you don't need too with these good quality tires (mickey Thompson's). I know that Cragar's can vibrate since there hard to get centered with the uni-lug pattern too.
That's bad advice right there. The rims could be out of balance if they're poorly made. I don't think I've ever seen a setup that didn't need tire weights.

Yes, very bad advice. Speaking from experience with MT tires, they can require a bit of weight to get them in balance.
