Yeah jacking it up will tell you a lot, like the above mentioned check all the obvious, if you can take your wheel and rock it back forth (with the bolts obviously all the way on) it's probably a wheel bearing.

I drove my Legacy with a bad wheel bearing for a while and the wheel didn't fall off, not saying you should but you should be able to make it to a place to get it fixed. Another thing to mention is when I had a bad one on the left, when I would take right turns it would change in tone.
