obviously it's impossible to tell without hearing the noise itself, but nevertheless ...
greasing the slip yolks is something that was common, but it's also something that i haven't done in ages. and as far as i recall i don't remember ever having to repeat the service if done with the PTFE lube. also, the 'noise' from that was just as often felt as a shudder as opposed to a clunk. still, it's an easy thing to check and remedy.
at that kind of mileage i'd be quite mindful of the rear end. when you talk of a clunk when starting from a dead stop - especially after changing direction (forward from reverse, or forward from park) - my mind immediately goes to excessive backlash between the rear crown and pinion.
the two piece shafts do get faulty steady bearings. we used to stock them when i worked on the east coast, but here in Alberta I'm yet to do one. instead i just rebuild rear ends like it's going out of style

Mine was definitely a "clunk" or "clank" noise. It was most noticeable if on a bit of an incline such as leaving a stop sign or light.I lubed the rear driveshaft splines as what was mentioned with the Ford spec grease and it was all good after that 
Mine is a 2012 SCAB 5.0 6.5' bed

I did this repair on my buddy's 2010 yesterday. Took about 20 minutes. Make sure you have some clamps to put the accordion boot back on correctly.
