Rattle under car?

I've got a low pitch rattle/rumble underneath my car and it does it at low speed, high speeds, accelerating, decelerating....no real way to diagnose it by those type of conditions. All I can tell is it's coming from underneath the car and I can slightly feel it through the floor board. Any ideas?

Worn front driveshaft or front diff bushings?

Thought about that last night. I'll let it sit a while and let everything cool down and see what I find. I'm guessing it'll have a lot of play if it's worn?

Lots of threads about the front driveshaft. I have not yet experienced it. Diff bushings cause more of a clunk but symptoms can manifest other places as well.

My front driveshaft has no play at all. Shook it as hard as I could and nothing.

It only does it for a second each time it does it and it sounds like a lower pitch version of something rattling in a can. It also seems like it does it more often when I'm coasting and/or braking.
