Within the past month, I've been hearing a thunk or clunk... sometimes, not everytime, when I accelerate from a stop.

I've heard it once when coming to a hard stop at the top of a hill.

At first I thought it was a nut that I had dropped, but that was more like 2 months ago and it was on the driver side. This sound is coming more towards the passenger side.

I checked out my Hayes book and it said it could be a worn/broken axle or CV joint. I don't friggin know, what do you think?
