front passenger side tire squealing

Lately my passenger side tire has been squealing whenever I step on the gas. When I'm driving normal I don't hear anything but when I accelerate to get to a high speed like to catch up with traffic or something is when it starts squealing. When it does squeal it does it for about 3 seconds or so. What could this be? I was thinking a ball bearing but I am not really sure. Let me know thanks.

start with checking the break pads they have a little metal peace on thme that squeels when your pads get worn...telling u to change them.
sometimes they only make noise when your stopping ...sometimes when you hit a bump or hit the gas ... it just depends on how the pad moves i guess.
if it was a bearing it would always make noise

Well I think I fix it. There is some type of shroud that goes behind the disc and all the other stuff. Well I bent the shroud back a little bit and the squealing went away...so hopefully that was it.
