It could be as simple as a ujoint in your rear driveshaft. When mine was going in the XJ you wouldn't notice it when it was loaded like when accelerating or maintaining speed, but as soon as you left off the gas the ujoint was loose enough to cause a vibration. Several on here will remember that I let it go a really long time and eventually it developed a squeak also as it rotated.
X2 on that. Check all your U Joints. I assume this started after our last trail run. A good visual inspection is always a good start.
I wish I could help you more but really need to drive it to diag it. Would be nice if you lived slightly closer. Just look closely into anything damaged like dents in the drive shafts witch can throw things out of balance. I no your RF lower controll arm got slightly bent but don"t feel that could cause a vibration unless it bent more later down the trail. I was very impressed that you picked every line that Will did & his Jeep has much more clearnace so again just look for trail damage.
The rock in the LR wheel. That was amazing!!!!
