Thanks guys. The manufacturer does really stand behind their product. The guy at Stillen was trying to blow me off till the manufacturer called them and now they are kissing my ass. They think the shaft is bad and are sending me another with no charges(not even shipping). He gave me the option and I told him I would try one more shaft before a refund. He did say that OE shafts are 2 piece for a reason. Noise dampening. I guess we'll see.
