Ok so I finally found out what's wrong with the stang, thank god. At about 5 pm today I go out start the car and I am listening to it idle and I hear like a whistling sound I'd guess you'd call it pretty loudly, like louder than my exhuast. I go in the house which is about 50 feet away from the car and you can clearly hear that sound still. So I get in and start driving to the gym and as I put it in 1st gear and get to like 1500 rpms I hear the sound and it gets louder as the rpms increase, same thing in 2nd, 3rd, 4th, and 5th gear. So I get to the gym and call my cousin Doug who works at the Ford dealership right in my town and explain it to him what I hear and tells me to bring it to him. So I bring it to him and he revs it and hears the sound so he takes out some tool not sure what it's called (looks like a stethoscope looking thing) and checks all the pulleys and the alternator with it and comes to find out that the idler pulley is about to go and the belt tensioner needs to be changed as well. So I went to NAPA and it ends up being like $50 for the tensioner assembly and $17 for the idler pulley which isn't too bad, $70 bucks. Probably gunna get it changed Thursday morning, just sucks I have to drive it to class tmrw with it sounding like shit but at least I know what's wrong with it now and it can get fixed finally!!
I really hope that the wheel bearing doesn't need to be greased up, not like that's a big job at all but I am pretty sure the sound it's been making was the between the tensioner and the idler pulley and it just got a lot worse sounding lol. As always thanks for all the help guys

, will keep updated if the sound goes away.
