with any transmission, if you do excessive one wheeled burnouts, the differential pin can cause damage. The trick is to not do one wheeled burnouts. Either "tune" your front suspension so that equal weight is on the front tires, or get a limited slip for the differential. You can also look into installing diff pin savers on the differential. They are just bracket like items that you bolt to the ring gear of the unit. They help in preventing the pin from working it's way out of the differential if the retaining pin fails.
