What is the popping sound?

Hey everyone. Just changed the front and rear suspension on my truck to Kings and Deaver U748's. Occasionally when going over small bumps the rear makes a "popping" sound, occasionally when I turn it does the same, and when stepping on the gas hard from a complete stop the rear makes the "popping" sound. What could this be?

I've checked all torque settings and everything is good, so I just can't figure it out.

Thanks for any help that y'all can give!

 

Not wanting to hi Jack but does it sound like what I'm hearing in mine?

I have a 11 second video, the where the noise is heard.
I did a suspension change as well around 2000 miles ago, only been hearing the noise for the past couple weeks.

 

When the popping started, I did leafs, shocks, and shackles. The diff drop was there even with my spacer lift so I don't think it would be that.

I don't
