Look closely at your power steering bracket if the engine in question is of a Magnum variety. IT MAY BE BENT.. Sounds odd, yes, but over and over again I have seen this. Since I work in the parts business I see silly things and this is one that even Ma Mopar knows about. If you have had an idler lock up, a water pump go, an AC Compressor lock up, or any other situation that stopped the belt DEAD in it's tracks, LOOK at the alignment of the P.S. Pulley. How this happens is beyond me, but it does.

Peace, Rev. Mopar
