Howdy. So I diagnosed and fixed my death wobble. A day later my jeep drove all day sounding and acting perfectly. This evening I drive 5 miles and great. Get on the highway and start hearing a loud roar in the rear end. After my exit it’s doing it all the time. Worse between-15-40 mph. Quite when I let off the gas. Differential? I joints? Not sure.
 
Hard to say for sure given such minimal information but I have seen a failed ring and pinion do exactly this
 
The noise could be the pinion bearing going bad, cracks in pinion/ring gear or even carrier bearings going bad...
You will need to provide more information...
Suggest you drain the gear lube from the rear differential and examine the lube for shiny particles or chunks... and inspect the ring gear for problems.
IF you are not sure of what to look for; I would suggest taking having a Jeep friend come over to diagnose the noise or take the Jeep to a driveline shop.
