losi LST2 diff pin problems

[doo540]

I'm having a small problem with the diff pins in my lst2, and looking for what you guys have run into and what you did to fix the problem. As the pics show I keep shearing the diff pin into 3 pieces. As you can see one side gear and diff output is split in half. I believe that one was from landing a jump under power, but the other two I believe just broke.
