D8T rear diff help

[nastety92]

So a few weeks I was out bashing my D8T with a friend and his Slash 4x4. We were at a constuction site and I went off of a large pile of soft sand and landed upside down on my lid.

After this the truck only had front wheel drive, no movement out of the rear end but it would roll smoothly.

This is a picture of the rear diff parts after disassembly.



My question is, what went wrong and how do I prevent this from happening again in the future?

Also, where do these ball bearings go and am I missing any.


Thank you very much for the help,
Nick
