vibrating from 30 to 40mph

I have an 02 se7 and it vibrates from 30 to 40. Just put new toyo opencountry ht all the way around but the problem was happening before. I also have when i push the gas pedal down and let of the press it again, it feels like the ujoint or something else is loose with the driveshaft. could this be the problem with the vibration? thanks for your help. stay muddy:confused:

Hmm you might want to post this on the Disco section as they will understand more about these new fangled coilers.

101 owners are used to vibration and prop shaft rumble and flat spots on the tyres. In fact if it ain't grumbling and shaking it's probably fallen off:)
