Noticeable clunk upon acceleration, sometimes turning

So I have a 2008 Colorado with about 156,000 miles on it. It has a leveling kit, Z71 4X4 Crew Cab. Been a pretty darn good truck and most of the miles are highway. Common wear out components are the only real issues she has given me. Lately, it has been developing a clunk that you can feel resonate in the body of the truck. This almost always happens at a dead stop on even ground. You will get a single clunk once it reaches about 5-10mph. If you are rolling through a turn especially a left one while decelerating and then accelerating again it gives you that same clunk. Not as frequent going to the right but it will do it on occasion. I just replaced both front hub bearings, and a new left upper control arm and ball joint.

I replaced both U joints on the rear shaft at the tranny neck and differential, one was a little tight but not really that bad, they were placed with Moog Aftermarket ones with grease fittings. I just changed the differential with royal purple but a few months ago. The clunk is still present. I checked the tranny mount and it appears solid. I retorqued all the U Bolts on the rear axle. They didnt budge and were right where they were supposed to be.

I had this clunk gone but by a strange occurrence. I put it in 4HI and it disappeared. However, I think from the power change to the front might have taken the load or body transferrance somewhere else. I put it back in 2WD and it returned shortly thereafter. It honestly sounds like it is coming from the rear a lot like a bad u joint. What else could I possibly check?

Check the sway bar, both the bushings and the end links. Worn end links are a frequent cause of clunking.
