TOY: Strange vibrations

[Leonel&Ami <aguila1@xxxxxxxxxxx>]

about a months after having my dual cases installed  i started to develop a
vibration at around 70-75 MPH,I went from a two piece CV d-line to a very
long one piece standard two joints driveshaft and it worked very smooth for
about a month but it started vibrating right after going to Hollister(mostly
dirt trails) to try it out.I have had the rear d-shaft
straighten,balanced,got new u-joints,had the wheels balane and
rotated,adjusted the pinion angle a bit it now sits at -1 degree but it
still vibrates and it is getting worse.City driving is fine but once I get
on the freeway it stars shaking.Any sugestions?
