No.
FYI
I got a new driveshaft, U-joints and slipyoke.
Put it on the outputshaft in many ways.
Didn't help a thing.
Very frustrating, I can tell you that.
Hope it helps for you if you decide to buy a new one.
Sidenote: It is hard to tell if people have the same problems when feeling a vibration of course.
It might work for you, the only way you can tell is to buy a new one, install it and see if your problem went away.

Sorry to heard it still did not work. I going to trying adjusting angle, etc....the conserative approach since the guys at the Mustang shop cannot guarantee that a new $500 driveshaft will eliminate my problem.

Crain -
Does the U joint angle on the axle equal the same angle on the transmission? It is common for people who put lifts on their truck to rotate the axle housing upward to lessen the angle on the axle U joint. The transmission U joint still has a steep angle, and while it may not be close to binding, it can cause an imbalance. So the blocks you used turned the housing slightly upward and it now gives you different angles on the front and rear U joints. Your best solution is to get a shaft with a double cardan joint on the transmission side of the shaft and have the whole assembly balanced on the truck at a machine shop. A double cardan joint is just a double U joint (fancy name) and I think its on all 4x4 F150s, but I'm positve it is on the shortbed 4x4 150s, like mine.
When I replaced the double U joints and the axle u joint, I had to bring the driveshaft to a machine shop to have the joints pressed out and the guy mentioned to have the shaft balanced when its back on the truck. From what he said, the axle yoke is not balanced by Ford and can add to the vibrations.
Sorry for the long post!
