So when I start my car I don't hear anything. I wait for a while I can hear a very low squeak. But when I put it in reverse or drive I can hear a semi loud squeaking noise I can have it in nuetrual and it wouldn't make the noise. I bet it to a local shop and end up paying 20 dollars and they couldn't find it. For some reason it wasn't making the noise then. I'm drive mg home and now I hear it again.

Its a 2006 it has 72,000 miles. Its my first time hearing this noise and is cold out. I didn't hear it last winter. Its a sound that seems to come and go. I'm thinking it could be a Pouilly bearing that didn't have grease. But that's me guessing. if I'm driving it goes away when I'm at the stoplight with the car still in drive then the noise comes. Now if i take offat 500rpms you dont hear the squeaking sound.

Mine was doing the same thing. If you are handy with a wrench then do this:
Remove the belt and start the car. Listen for the squeak. If it is gone, then it is belt related.
Spin the idler pulley and the belt tensioner pulley by hand and see if you can hear any noise or do they spin smooth? My idler pulley was the culprit. $40 online from Park Place and 30 minutes work, squeak gone. Keep in mind that you have the AC pulley, water pump pulley, crankshaft pulley and alternator pulley that are also spin when the belt is in place. Any one of these could be the problem. Start with the simplest and the ones you can get at easily. Also, as stated above, if the belt hasn't been changed in a while, might as well do it now. They are fairly inexpensive. A decent belt (Toyota/Denso) should be good for at least 60k miles or 5 years but they are made of rubber and do need to be changed routinely.
PS, if the squeak is still there when the belt is removed, then it has to be something internal to the engine and better left for the experts.
