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...
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.
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.
