Those pins under the sun gear/the out drive pin, they are the weakest link of the XXL diff. I've read where a guy on the LST forum uses colbolt drill bits and they have yet to break, but now he's breaking gears.
I'll rather replace the pin than mess with the gear pieces and chunks that get all m ixed up in the fluid ?

I used to run heavy wt diff fluid but I've dropped down to 15K and i haven't broken a pin in a while now.
