2004 Mustang has Squeaky alternator pulley
I have a 2004 3.8L Mustang. Recently I've been hearing squeaking noise coming from under my hood. It has gradually been getting worse and worse. Today I decided to take off my belt and spin each pulley individually. When i spun my alternator pulley, it made a slight, but audible squeaking noise. Does this mean I need to replace my alternator?
What can I do to reduce the noise in the meantime?
