I am running an 8 rib setup with a vortech supercharger. Recently I have been having belt problems. Come to find out the power steering pulley had moved on the shaft about 1/8". I pressed the pulley back to where it should be yesterday, was driving the truck today doing some ve tuning and it toasted another belt. After looking, i found that the power steering pulley had moved out again. Anyone ever seen anything like this, or have any idea why it would be moving? Thanks.
