so u r saying that 3 remanufactured alternators all have made the same whining sound and have went bad witin 2 months each

the one that is in it now is from advanced auto and its doing the same thing as the 2 from pepboys and this one is a different brand

thats like 1 in a million that 3 remanufactured alternators 1a different brand would all make the same sound and keep going out did u read all the problems people were having with the 06 mustangs and the had to put extra ground wires and all kinds of diffrent things to get it to stop the one lady bought a brand new one with a 5 year warranty and its still doing it put none of them said it was a whining noise and it was messing up ther batteries to my battery has been fine dont make no sense

I had half a dozen Pep Boys alternators go bad on a Toyota I had many years ago. They always replaced them under warranty. Finally I got my money back, bought a good one and never had another problem. Cheap junk is cheap junk!
