Whining noise maybe grinding noise?

[ShoTownsend]

When I start car and reverse out driveway I get a moaning noise or howling noise then it goes away after 20 secs. Park car couple hours come out crank back out it does it again. Does anybody know what this is its kinda high pitched and then goes away and drives fine after that.

Could be the serpentine belt tensioner, ac compressor bearing or alternator.

Ok thanks guys I just inherited car so its not been run hard also its probably just had Oil changes too and no real real maintenance as I've read on here few other things that should have been done. Ill go give her a once over and try to pinpoint problem a friend said bearing as well. Do u think it could be a wheel bearing it kinda sounds as if its coming from the right front I just asked my girl as I'm typing this where do u think that sound is coming from and she said tire passenger side

Jack car up, grab tire at top and bottom, push/pull top bottom alternately. Doing so will indicate if there is playb in the wheel bearing(s). If you have movement, replace bearing.
