about 2 mins? but it goes away after driving a little, is this normal or will the problem get worse?

really depends on where its comin from..could be anything from a/c compressor goin bad to an axle bearing. if its comeing from the front of the engine..take ya belt off an spin the pullys..like smog pump, a/c compressor, power steering pump,ect.. an listen for any noises that sounds like the 1 ya hearing...if ya hear it jus when ya moveing could be axle bearings
