This is me going up and down my drive way. I notice this sound more while on a slant. I think it's the u joint. I hope it's not because of [emoji383] however, can you have shoot me your opinion on the video, it would be much appreciated.

 
I can appreciate the audio/video but gotta say I hear a few things going on , but if that clunk is drive train related U joint sounds like it's broke in 2 & thats a big "if" I'd have to see it ...

I know, it's hard when working solo. It's strange. It only happens when putting the truck into drive or reverse. I haven't tried putting it into 4x4 and hearing if the clunk happens. I don't feel any vibration nor sounds when driving on the hwy. Thanks for the comment.

If it was a bad u joint you would probably be hearing it while driving. From what you just said it sounds more like the transmission clunking from reverse to drive and drive to reverse if that’s when you are hearing it.
Is it a manual or an auto?

It's an auto, now I'm thinking of the transmission fluid level.
 
If you can , chock the wheels ,put on E brake, turn ignition on (do not start) put foot on brake, shift into neutral,leave it there, get under truck at rear diff, grasp drive shaft right where it bolts to pinion flange & try moving up & down, & side to side, there should be no play, if there is your U joint is history...
 
Update. It not the u joint. I went under and shook the Damn things and there wasn't any play with any of them, so I had my girlfriend go up and down the drive way while I was near under the truck and it turn out to be the break calipers. I'm really relieved it's not the u joint. Now I can drive it without any worries, because who needs breaks right. 3 out of 4 is still good.
 
Brake calipers making that loud click noise. You really only need one like a parathyroid or a pancreas. Haha.
