Vibration in the frame
My 92' F150 4x4 developed quite the vibration. I can feel it while accelerating but goes away letting off the gas around 25-40mph but after 55+ is very noticeable regardless of accelerating or not, in neutral even.

The driveshaft will HAVE to come out................ Oh you could lay under it and fumble around with a press and get the joints in "maybe" but the best way is going to be remove the shaft and get it out where you can work on it....

In neutral you won't feel vibration from any u-joint, vibration in neutral idling only points at two possible causes: Engine or Transmision (this includes the Torque Converter) problems. The first one to check should be the Engine mounts, they have steel and rubber, see if the rubber is broken (take a good look, sometimes it's hard to spot any cracks), then check if the Engine needs a tune up, if it isn't working right it could vibrate. Then check the Transmision mounts (idk if they have several, i recall just one and usually only the Broncos have them), then check the Torque Converter.
In any case, there could be several factors at work causes some degree of vibration, worn u-joints, worn or deformed tires, broken bearings, frame cracks or broken weldings, radius arm bracket failures, Broken differentials (either the bearings or broken teeth in any of the gears)... Those are all i can recall right now, but i'm sure there are some more. As you can see, all the ones in this paragraph are of dinamic nature, which means you'll only perceive them while driving.

If he means stopped in neutral then I agree, but if he clicks it into neutral at speed and coasts then a U-Joint can still cause vibration.

The engine is running a-ok and the tires are about 7,000 miles old.
My u joint was squeaking already, and I had gotten stuck in mud, I'm sure the u joint didn't like the stress of rocking the truck in 4x4 to get out.
