Had "Death Wobble" last year. Seeing it is one thing. If you experience it, it's truly terrifying on a busy highway. Great job on the videos. Thank you for the time and effort!
Put your GoPro on the ground in front of your jeep with all the weight of the jeep sitting like normal, get in the Jeep, start it and then turn the wheel back-and-forth with the GoPro filming, and you’ll see what moves the most and needs attention.
While you can get death wobble from failure of any one component, it's often wear in several parts that add up to oscillating instability. With lifted vehicles in general you have to inspect very carefully and routinely for wear.
1996 Jeep zj 4.0 has stock everything no lift . Owned a couple months, and bam death wobble at 35+mph I see everyone say 50-60 mine starts at 35 you feel a light shake then 40 it just goes nuts. So many bushing are split all original parts from the 96
