Yes im sorry I did replace the assembly as well as the harmonic balancer and the idler pullley also im thinking its must be the a/c compressor (piston) now its only making the sound when a/c is on but goes away when you take off.

Have you tried spinning the a/c compressor pulley with the belt off and seeing if it moved side to side?Also have you tried spinning and seeing if the a/c compressor clutch was loose?
