      Hey Nick,
      I have an easy fix for you and it won't cost you a dime out of your pocket. Simply don't go over 70 mph, and you won't feel it.

      Do you feel the vibration in the steering wheel, or do you feel it more in the seat?
      If it's in the steering wheel, then it's probably in the frontend.
      If you feel it more in the seat, then it could be the driveshaft, or rearend, ect. I would also have the wheels checked out just in case one of the wheel weights fell off.
      I'm sure someone else will think of other possibilites, but this is a start.
      Good luck!

        Does it go away above 75/80? Could be wheel balance, belt seperation in one of the tires.

          well just got the front tires balanced yesterday and i admit it did help a lil bit. at least i can see the left side mirror not shaking.

          it still shakes at any speed above 70

          and i can barley, i mean barley fell it in the wheel but when i driving i can see my PASS seat going back-forth like its on drugs.

                  engine mounts.

                  put the car in Drive or Reverse
                  pop the hood.
                  brake torque it very slowly add more gas and watch for the engine twisting.
                  obviously will need 2 people to do this.

                  mine twisted so bad the exhaust would hit part of the frame. (old 98 ls1)

                    It could be a series of things, bent driveshaft, bent rim, bent axle shaft. Id start w rims and driveshaft.

                        I had a vibration for a little while, it was because the U-Joint on the driveshaft was not centered in the yoke. Loosened the two clamps on the rear diff that hold the shaft on and centered it and it was gone.

                          thanks everyone i really love this site for input, well i got my fronts balanced and seemed to help a lot. i at least can take a freeway ride for a while without my cheeks jigleing. i will do my rear tires balancing this monday and if its not gone yet ill start the cancelling out progress. and least i can see my left side mirror and all.

                          and hope its not that major but if it is i still got a ext warrenty
