The squeal you speak of is belt related, yes; but it is not the belt. There is a belt tensioner ( the part you had to pull up to remove and replace the belt). Inside this tensioner, the bearing goes bad causing the squealing sound you describe. Replace the tensioner (pulley or assembly) and the noise will go away.

I had the same problem, so I took the belt off and washed it in soapy water. I then took a wet, soapy cloth and wiped off all of the pulleys. The squeal in my Aerostar was caused by a leaking power steering pump, which leaked fluid on the belt, causing it to slip and squeal.
