93 Jeep Wrangler knocking noise from drivetrain

[Cjackson]

Hello all just been working on my Jeep trying to figure out where this knocking noise is coming from. I started with the rear end and worked my way to the front, looked everything over made sure all bolts were tight, checked all U-Joints, checked suspension and everything seems to look just fine. Just curious if anyone has any ideas where it could be coming from before i start to tear into transfer case/ transmission?

Its really hard from a video. A few things could be a chipped ring gear,chipped spiders, something came apart in the brakes?? Id put it up on jack stands ate spin each wheel and even give a in gear no gas test and see if it happens in every gear or?? Don't sound like engine or clutch but again its hard to tell.

it is not the engine I made sure of that, I just haven’t checked the clutch. I checked the breaks and all seem good. and it only does it when I accelerate in every gear but when I let off the accelerator then the noise stops
