Every complex mechanical system in use has a weak spot. In this system it just happens to be the spyder gears. It's not an intentionally weak design. I'm sure they weighed all of the consequences of different systems and chose the one that produced the quality they desired at the cheapest cost of production. They don't use a standard live axle system like the rear axle of a car or truck because it would give them a horribly low hanging differential and axle tube that no one would like.
