Driveshaft U joint or driveshaft slip joint. For the slip joint use a good Teflon grease and lube it up. Ford has a TSB out on the slip joint issue.
Check the u-joints at the drive shaft.
TSB technical service bulletin. It's when the manufacturer acknowledges a problem and offers a solution but stops short of being a recall. Here is another forum post on the TSB: https://www.fordf150.net/forums/viewtopic.php?t=17515
