Death Wobble?

So I was riding around with my buddies and gave the 350 a little hell. I was running up a hill turning slightly at about 55 in 5th and it just starts hopping on me. Really bad. Scared the $hit out of me actually. I thought I had broke something. I slowed down to 35 and went a half a mile or so, then got back up to 60 with no effects. It's been aligned, but I've always had a little vibration right around 60 that goes away above or below that. What would be causing this sort of thing?

Of KNOWN problems:

Dual mass flywheel going out (it rattles at stoplights and such)
Hubs going bad (they knock in 4x4, even on dirt)
60mph vibration

Is it a kingpin 60 or a ball joint 60?

My brother's truck did the same thing. I turned out that the front tires were old and the sidewalls were breaking down. I know it sounds wierd but we put new tires on it and the problem went away. You need to look at the date of manufacter on your tires.

When I bought my F250 it had a 4" lift.Previose owner took off his big tires and wheels and put smaller size tires and wheels.The tires he put on it were brand new.I had death wobble real bad.Ford stealership said it was the front end.Had the front end done.Still death wobble.Stealership said its brakes.Had the brakes done.still death wobble.A friend of mine suggested that the tires were to small.I went and put a bigger tire all the way around.Viola no more death wobble.I just wish he would have said something before I sunk 3grand in it!
