Noise from rear end?

I have a 98 tj with 3 inch body, 4 inch suspension, running 35's and ford 8.8 axles. Having lots of heavy vibrations and a clunking noise from what I assume is the rear end. Clunking is more aggressive the more I get on the throttle. Recently had rear upper and front lower control arms replaced, bushings were shot and I was told that would fix the issue. It helped but not fixed. Also was told u-joints and yokes are solid. I'm at a loss for how to fix this, any advice would be great.

Best case scenario is you need a standard $30 u-joint and about an hour to install it.

Worst case is you ignore it, u-joint breaks, driveline falls out, you kill someone on the highway with it and lose everything.

Likely case is you need a new rear driveline because the yoke is wallowed out from the bad u-joint.

Either way, get it fixed, it's not safe to drive a vehicle with driveline slop.
