I fear the alternator in my new(to me) 04 4.4L is in need of an alternator. There is a horrible rattling sound coming from the alternator that sounds to me like a worn bearing.

I'm confused when a previous post mentioned the alternator leaking. Am I missing something? What would be leaking from the alternator?

I'm very familiar with charging systems of domestic vehicles, 10/12SI and CS style charging systems. This makes no sense.

Is there any alternate way to get the alternator out without opening up the cooling system?

Second question, what brand alternators were you guys using that only lasted a year? I want to avoid those...

Last question, does anybody know what a shop charges for alternator replacement?

thanks,
