The failure according to Mark at Toyota Tsusho America (OS Giken's US distributor) is "cooking the oil" due to limited fluid capacity, which in turn can and did lead to a side gear failure. They are apparently now shipping units with strengthened side gears.
I would love to see pictures as well

It looked like they used a generic side gear with an application specific piece pressed in for where the axles come in (yes, I know, not a very technical description, but hopefully you get it). Where those two metals met, it very clearly failed and sheared apart. Once the side gears failed, they took out the spider gears, and the whole thing got chunky - quick.
I hope to have the new diff very soon... unfortunately our season here is almost over

I never got a close up of the side gear where it failed, just a pic showing "OMG that's a lot of chunks!" and the second diff wasn't as bad (I knew what to look / feel for better so we stopped and pulled the diff before it turned into a complete pile of metal shards)

They would be a lot more valuable to this thread. Who else had failires besides you and what suspension and size/model tires do you run?

I don't have a place to publicly host the pics to link to here.
I have Penske double adjustables and multiple sets of wheels / tires (pretty much all STR options)
