Driveline Vibrations

Ok I am getting close on this and cant quite get it to go away, I have a CV Driveshaft and it is within 1* at the rear yoke I get the usual "cyclical vibration" between 50-55mph slower than that and above that there are no vibrations only in that speed range, what else could it be, my driveshaft is a TomWoods and had the same problem with my old driveshaft (So I dont think that it is out of balance). I have a 4" suspension lift.

I get noises at that speed when a tire is out of balance. That seems to be about where tires change from compression (going slow) to expanded (going fast) so they float a bit there and if out of balance it will harmonic and show there first.

After a bit of this, the tread usually scallops...
