Thanks PKRWUD, I was hoping you, unit , workcar or one of you gurus would read this.

Matter of fact I did replace fan clutch no help.
Could be clutch I wouldn't know?
Agian, it doesn't do it while not moving (reving motor) but it will
upon deceleration in neutral.
Could that still be clutch?
Mabye input shaft?
Since I got gears the driveshaft vibrates some at high speed, but this just developed recently?
I HATE IT!!
P.S. Definently not resonance
Thanks guys!
