AC tensioner makes noise - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ok...asking for a friend of mine. He has one of those 03 GMC with the quadsteer. What happened was his AC belt broke. It was determined that the tensioner was the problem so he replaced it and the belt. Now at 2000rpm or more the thing makes a terrible noise like it's hitting something. Anyone have any thoughts on this???
