Well i figured out what was the cause of my problem... The harmonic balancer came apart... The rubber came apart between the two pieces and the outer ring spun at a different speed than the inner ring when there was a load (AC ON) on the motor.
Took me a couple hours and i had my truck working like new again
I took the belt off and the outer ring just fell off
New balancer cost me 141 after tax from ford, And it was a redesigned part
