I will try that tomorrow

I replaced the whole unit just to be on the safe side. I even left the wrench in the slot and had someone start it so I could add tension to it, just to see if the spring was worn. Still Squeak - Squeak - Squeak

Since we're kinda running out of options, does it squeak with the old belt now...I've had new belts squeak.
I will also try that tap on the alternator tomorrow, if it still squeaks I might end up doing the tap with a sledge hammer
