Drive line vibration - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have the truck together and have test driven it several times, the problem is a vibration that seems to get worse the faster I go. Had the drive shaft balanced and new joints installed. How would you check a two piece drive shaft angle, I thought because it was two piece that the rear end trany angle did not matter because of the carrier bearing, if this is not right how do you set the angle since the drive shaft flexes in the middle. Also any ideas as to what might cause the vibration, I lowered the truck 3" in back and 2" in front installed sway bars on both ends and had a eaton posi with 4:10 gears installed and I have 700r4 trany (which I am having issues with getting the TV cable adjusted properly).
Thanks
JC
