I have the same truck with the same problem, I bought the truck with 20,000 miles on it, now has 124K on it.
The problem still exists
The dealer replaced the driveshaft 2 times, yolk, ujoints, etc.
Finally at around 60K miles the dealer told me it was the transfer case and that it was out of warranty. I think Ford should come up with an explanation!
Quite an annoyance for an otherwise nice truck.
