Great info. Now, what happens if you go over 6 degree on caster?
For example, 7 or 8 degrees? Is that when people start experiencing drive shaft vibration? Of course with the FAD, you won’t feel it in 2 wheel drive but will it be felt on 4 wheel drive?
Sorry if I’m making this complicated. Id like to just know why you can’t go 7 or 8 degrees.

I’d try and stay around 5.5-6.0. After 6 you start getting into the front pinion pointing down. I’m running right at 6 with 3.5” lift and no driveline vibration in 4hi on the highway. It drives really nice too with those numbers. Factory my rubicon was right at 4.0.
