I always thought that if a pulley or belt was worn enough that the belt touched the bottom of the groove that that WAS the problem (but I may be all wrong there). if your pulleys are aligned) & belt tight which I'm sure it is by now) then it about has to be wrong/worn belt (likely) or worn pulley (way less likely). Holler how it goes.

Old change the belts to dayco top cog as in earlier post. My hemi would throw and break belts at rpms until I switched. No problems in 8 years. I was able to get a deal on a bunch of different sized unused belts from a nascar team to see what length fit best. I ended up with the 15470 for alternator and 15440 for power steering.
The first 2 numbers mean it’s 15mm or 7/16 wide the last 3 are length. The last number can be a 5 for half inch. So if yours fix good just measure them in inches and add that number to the 15.
I will bet your problem will be over with the new belts.

I will bet your problem will be over with the new belts. The first 2 numbers are the width- 15 mm, the last 3 numbers are the length-47 and 44 inches long. All of our older Mopars were designed to use the 13 mm wide belts, pretty much unavailable today. 95 % of the Mopars use the 15 series belt which ride up out of the pulley a little amount.

Thanks lemondana I stand corrected. I was going off of memory which wasn't working correctly. But I do know theses belts work.
