That first pulley looks warped. I'd be looking at the pulleys, tensioner, idlers, alignment issues ect.

When you put the belt on. Everything is moving smoothly, no catching or sounds, I just replaced the belt tensioner and ac compressor yesterday.

Something is either out of alignment with the pulleys or one of the pulleys, idler pulley, may not be turning. Or I see a lot of build up in the power steering pulley from the belt. You can not just throw a serpentine belt on without cleaning out all the grooves in each pulley. Look to see that when putting on the serpentine belt that every pulley is in line with each other, no pulleys cocked. The belt must run true.
