07' Rear driveline vibration at all speeds. Once piece.
On my 07' I bought it home mid AUG. It has been getting much worse to a point there is a rear driveline vibration at all speeds above 40 and up to 70. I used to change intensity whether you are on or off the gas, and would almost vanish if in neutral. However now it is all the time.
I cannot feel any play on the u-joints, the yoke has a little play in the xfer case but is is normal like on most other trucks I have owned, and the pinion flange is nice and tight.
Could this be **tight** ujoints or the driveshaft itself? It looks rusty, but there are no dents on it.

Anyone? Would really like to tack this at 4:30 today as I only have this window to do it this week.
I am leaning towards u-joints, but the fact the vibration is occuring during + or - acceleration, leads me to beleive not.

Here is a technical service bulletin that has a great diagnostic chart for vibrations.

It was a tight rear u-joint. It was original from ford and I had driven it approx 800 miles with this vibration, and pulled some heavy trailers. It must be super strong metal as it did not wear down.
The front was original as well so I left it alone. I am always amazed at the quality of the ford joints. The only reason it failed was due to the seals going bad and the grease vanishing.
