Not sure, but it makes sense to me.
So like was said, take off your front ds try to find where the prob is.

Oh I see. So what you are saying is that the bad joints on my driveshaft didn't seem so bad when my driveshaft was spinning slower? So there is not a new problem, just an old one that has come to light? It's starting to make some more sense. In that case is it a good idea for a new front ds anyway with a 6.5 in lift? Shouldn't it be a little longer to put my axel where it should be?

If your vibes are the same at 50 as they were at around 70 you don't have a "new" problem.
