Im confused what you mean by body lift? Surely that shouldnt change the angle of the cv's? I have a 2.5 inch spacer lift myself and the angle hasnt caused an issue yet. I often disconnect sway bars and climb up mountains around here. The stock CVs are pretty durable on the QD system. Are you sure they werent run without grease? Mine has a tear in the boot and Im sure eventually it will go, if all the grease leaks out.
