Squeaky noise

I got a 95 Pathfinder SE 4x4 and I noticed that every summer I always get this squeaky noise whenever I'm slowing down or starting to move. Once I get my speed up, I don't hear the noise anymore. It sounds like its coming from the wheels. At first I thought it was the alternator, but it doesn't make the sound when the vehicle is completely stopped. I tried reving the engine to see if it will do it and it doesn't. Has anybody had this problem before?

Sounds like some worn or dirty brake pads to me

could be a bad wheel bearing... but Im no expert... if it were breaks you should only hear it durring breaking or on turns...

I think brakes as well. They can squeek when not in use. Not quite sure why. Mine do that on the Sentra. It seems to be a chronic problem. It doesn't harm anything, it is just annoying. Does the noise go away when you apply the brakes?
