Yes the truck does have a splined two piece driveshaft. I have greased up the splines and reassembled, but I just used regular axle grease. I'll pick up a tube of that motorcraft grease and give it a shot! Thanks!

If you've already greased it then it may be a long shot. Still, I guess it would still be worth a try and you would have the benefit of having the correct Motorcraft product on the joint. I hope it solves the issue.
Yeah, you never know. Maybe if that's not the issue the troll dung will be strong enough to fix the problem by osmosis.
Well, you guys may have been on to something. Today I changed out the U Joints in the driveshaft, because after my own inspection I found a bit of play in them. So I changed them out, and the vibration was still there. But while I was under there I greased up the slip joint as well. And while the vibration isnt gone, the clunk was gone for a little while. I drove it over a few corners where it always clunks, and it didn't clunk. Eventually it starting clunking somewhat quietly, I assume after the grease got pushed out. So I'm thinking the source of the clunk and possibly some of the vibration may be from the slip joint. I got back underneath and noticed a small amount of rotational play in the joint, but no up/down or side to side play.
I guess be ordering a slip joint and replacing it.

I'm can be cheap too but with all the work I have into this damn thing, I really want it to go smoothly down the road. Plus noise and vibrations are a peeve of mine.
Well I replaced both the slip yoke at the support bushing and the one that splines into the transfer case. I bought a pair of used yokes from a driveshaft shop at about half the price of new. I had to grind the retainer clips down a little thinner so they would fit in the groove on the one yoke, but I did get the u joint in. The vibration is much, much better. Probably 80-90% better. So now I've got two new Yokes, a new center support bearing and three new u joints, so the rear driveshafts are practically new. Still have a clunk noise, though. I'll figure it out eventually.
I figured out my clunk noise 
. The passenger side fender lip at the very back was coming in contact with the dogleg part of the A pillar. So I shimmed the fender out 1/4" or so and its gone. I'm just glad I figured it out and it wasn't anything major.
Also I replaced the A/C hose that had a hole in it and charged up the system. The compressor is a little noisy, but the A/C is nice and cold now. I also picked up a better blower motor at the junkyard, the one in the truck was pretty weak. Installed the new one and the airflow is much better.
I picked up an auto dimming mirror from the junkyard out of a Bronco to replace the stained flip tab mirror in my truck. I wired it up to find out that it doesnt work. It still looks better than the other mirror so it's staying.
I will get pictures soon.
