When going foward today we started hearing this sound from the passenger side of front end, it kindof sounded like a gringing sound, so we took off the front wheel and looked at the brake pads thinking that there may have been a rock stuck in it. nothing. put it back together and started to drive again and heard it again so I brought it back home and parked it.

A little background about today, we drove approx 400 miles before we started hearing the noise.

Could it be a wheel bearing?
There is a little play in the tire from top to bottom. and a little side to side.
Anything else it might be?

I drove it tonight after it had plenty of time to cool down and didnt hear any noise but I only drove for about a mile or so.
