Yep blew up a front diff yesterday. Stripped two teeth off a planetary and shattered a sun gear. Yep need to get a shim kit. It is rebuilt now but I think the main reason for the break age is power on landing

Absolutely this. Landing under power will destroy, as you're seeing now, gears very easily.
I’ve conditioned myself to instantly let off the throttle the instant I see the wheels touch on the landing. After a while it becomes second nature.
 
I'd replace everything inside that diff.

Oh I am going to. Even though it sheer off the output drive cup and the gears looks fine it still could have stressed and partially cracked it. No amount of shimming would have saved me from this break. I landed with the wheels still spinning.
 
I did the same thing to my rear diff. I forgot to let off when landing and it only takes once.
