What could cause nasty loud vibration from the back of my stang at 95+ MPH?

What is with the really loud noise comming from the rear of my stang at 95+MPH. I am going to be driving my stang on the autobahn in Germany in less than 4 months so I need to have this resolved.

noise and vibration from the rear? does it sound like its coming from the differential? does it do it in motion or just with the vehicle on?

u-joint???

U-joint, bad differential, or bearings and seals on the end worn out.

The noise only happens in motion and only at speed now 80+MPH and especially it seems on very windy days or in a cross wind. I was thinking that the spoiler (stock) may be vibrating or causeing the truck lid to vibrate. Any ideas? The u joint doesent make sense to me I only have 10000 miles on her.

I had a Fiero once with the same problem . . . It was the spoiler . . . It seems someone tried to rip it off and yanked it until it came loose when they were disturbed. Happened at the airport, didn't hear anything about it until I finally took it to the dealer, who had a bunch of cars with the same problem.
