Holy vibration batman!!!
When I get my '72 F150 up to about 50mph, it suddenly begins to shake VIOLENTLY, the first time it happened I thought I was going to die. I feel the shaking mostly in the steering wheel. Once started the vibration doesn't quit until back down around 20mph. Whats going on here?

Sounds like your drive shaft has a bad U joint. Might want to check out the truck too....

Was this a case of the feared "death wobble"?

Really bad steering joint, or u-joints, my joints were loose, and the whole truck had a constant vibration thru-out at around the same speed. Is your steering jerking you around side to side when you hit ruts, or potholes?

I had a truck that someone installed the wrong size pitman arm on (alittle loose). If you hit a pothole around 45-50 mph You'd lose any control over steering or brakes and usually run off the road. It sounded and felt like you were going to die.

Sounds like a tire that is badly out of balance, with poor shocks. Is the tread cupped or worn ?
