Another front end clunk thread

Just like the title says. Seeking assistance diagnosing the clunk in the front drivers side of my truck. Vitals on truck: 2008 DCLB 4x4, OME 885 w/ nitro chargers (purchased pre-assembled from toytec, no top plate spacer) LR UCA, Dakars; 150k on the truck, about 50k on the aftermarket suspension.
The clunk occurs when the suspension cycles, i.e. speed bumps, pot holes, railroad crossings. It doesn't occur ever time I drive over said obstacles, but more often than not. I've included a video of the sound. Sorry for the length of the clip. The clunk is around the 0:30 sec mark.

So far I have already confirmed proper torque on all lower control arm bolts, lower shock mount bolts and cab mount bolts. I've also installed and/or replaced sway bar relocate brackets, sway bar bushings, sway bar end links.
The lower and upper ball joints appear to be ok, but I cannot say for sure that aren't in need of replacement. The bellow around my drivers side inner tie rod has been seeping for a while, but I haven't noticed any steering issues so I don't think that has anything to do with the clunk.
Sorry for the lengthy post. Any assistance is appreciated.

 

I have a similar suspension and had the clunks as well. Mine turned out to be the diff drop. Took it off and clunks went away.

 

I do not have a diff drop kit installed. Thanks for the suggestion though.

 

No problem. Good luck on on figuring it out!
