Ok so I’m stumped. So I bought a Zj and I lifted it 3in. I changed the all steering components. And track bar. I know there can be death wobble but hear me out. Can there be death wobble when all wheels are jacked up? I never knew I had this problem until I took it on the highway. . I’m driving and the front starts shacking at about 50 miles and then calms down around 60 then it starts again if I go higher. So I took it home and jacked it up. Checked if anything was loose. Steering, suspension etc. Nothing so I turn on Jeep let it run in D on jacks and nothing but when I rev it up it starts shaking again. So I thought maybe the wheel are unbalanced I took the wheels off rotors and pads. But even with all that off it still starts to shake. Is this a sign of worn or bad axles? The driveshaft is not at a bad angle I checked the degrees on it and they off by .5. If this is a sign of unaligned issues where can the issue be?
many help in advance is super appreciated.

Just checked the driveline . The front to be exact. I wiggled the yolk side it’s tight but towards the transfer case it has a small click click. I wiggled every u joint to the transfer case to which is bad but even at the transfer case I feel a shake. Can this be a bad transfer case?
