Thats most likely because you didnt shim the bevel gears properly or at all, or didnt bother to do routine maintenance to check them for grooving(which they will do over time). From the factory the bevel gears use no or only one shim per bevel gear. I have found that for proper backlash setting a combo of 2 or 2 opposing 3 is correct for shimming the bevel gears in the diff cups. If you dont do this the bevel gears will float excessively and grive the diff pins which regardless should be replaced every 3-4 gallons of hard use anyway or when they start to develop a groove pattern where the gears ride them.
As fo9r your broken outdrive cup from your BL LST2 I answered the most probable cause of issue in the other thread and how to properly correct that potential issue when using a KV motor.
