2006 4.7L Belt Squeal

I have a 2006 Commander with the 4.7L (104,000 miles). I'm having an issue with the serpentine belt squealing when started and the A/C is on. Once the pressure has released off the A/C compressor the squeal goes away. My questions is should I replace the belt or the tensioner?

Thanks,

Neal

Are you sure the squeal isn't from the AC pulley? It might just be the belt. Put some baby powder on the belt, if the squeak goes away it is just the belt.
