[carno]

my 2001 buick regal gs makes a whining noise when I accelerate and it moans when I turn my wheels, I recently had the power steering fluid replaced and the power steering was fine apparently. The moaning doesn't happen all the time but the whining with acceleration does. I have heard this noise before with an alternator on a Saturn twin cam I had as a teen, so I suspect the alternator is there an easy way to diagnosis this problem. If I have to take the alternator out how do I do this? I also heard it could be a belt from someone online that this has happened to before if so is it easy to replace?
