tore it apart again, took off the new pulley's and made sure they were torqued to spec. All good, took off A/C belt and the sound went away so I removed the pulley and it sounded shot so hopefully this was the issue and if so I suggest to just replace all 3 while you have the front end apart especially if your an automatic. If it turns out its something else I will report back
