The marbles in my head started rolling around again earlier and they came up with this question randomly.
I have seen pictures of guys that have done 4x4 swaps and literally destroyed their transfer cases with no real analysis as to what exactly caused the destruction in the first place.
So the marbles in my head asked... Should the length of travel in a driveshaft slip yoke be at least equal to the distance your axle travels before making contact with the suspension bump stops?
