Driveline clunk after 2.5 inch lift, who can balance a driveshaft properly?

[phineasfogg]

I lifted my 2016 Wrangler about three months ago and ever since there has been this clunk when I shift from park to drive or when I let off the gas at low speed, plus a vibration that comes in around 60 to 70 km/h that was never there before. I replaced the U-joints myself thinking that would fix it but the clunk is still there and honestly the vibration might be slightly worse, so now I am thinking the driveshaft itself needs to be balanced or maybe the pinion angle is off. A guy in my offroad group said he took his to an expert Jeep driveshaft workshop after his lift and they fixed it in a day, but he could not remember the name of the place, just that it was somewhere in Mussafah. I do not want to keep throwing parts at it and I definitely do not want to damage the transfer case, so I am hoping someone here can point me to a shop that actually understands lifted Jeeps and knows how to check angles and balance a shaft properly. Also is it normal for a small lift to cause this or did I mess something up during install? Any advice would be appreciated because the vibration is ruining my daily drive.
