3.7 L I had this same issue
i have what i believe is a slip yoke problem.
Problem=When coming to complete stop i get a clunk/thump noise from rear of truck. may also thump clunk when taking off from stop.
my truck is 2011 f150 lariat 2wd ecoboost
I took to dealer and they said they can not replicate problem. so now i will have to take back. I have seen tsb's for 2010 models but not for the 2011. i was wondering if the 2011 and 2010 had same slip yoke. i found a really good video of a raptor on youtube having this issue.
i can't say for sure this is my issue but is sounds very similar.

I had the same issue on my 2011 F150. The service manager knew right away what the issue was. He said the grease or lubricant has dried up in the yoke causing this issue. He said the problem was so common he trained the Oil Lube Techs to grease the yoke again. Since they did this I have not had an issue with the Thunk at take off or when stopping. It was so annoying. Here I had this new truck and thought I was going to have transmission problems soon. It cost me $108.

I have a 2011 screw XLT, 5.0, and have started noticing the same problem. A clunk almost everytime I start from a dead stop. Not severe, but noticeable. A coworker has a 2012 and told me there is a tech bulletin regarding the grease used at the factory for the yoke. Allegedly it was too low a viscosity and is causing the issue? Mine has 47k miles, so not under warranty any longer, but am considering contacting my local dealer for advice.

its actually a bad design. I got my service writer to order me a new 2 peice driveshaft with the nickle plated yoke and have never had the problem again.

2010 F150 Lariat Slip/bump coming from rear
I just got this annoying slip/bump fixed!!! The slip yolk just needed grease(it was completely bare)! There is a TSB for it: http://www.revbase.com/BBBMotor/TSb/DownloadPdf?id=177141
The job only took 20 minutes with a lift! I love love love my truck again!
