Yes there is an easy way to tell if you have the soft pins. Open the diff. If there are pins in there.... They are soft.

I can understand the diff componenets generating enough heat to warp the plastic diff cup around the metal insert.

Just curious, did you apply any grease around the outputs (ie between the outputs and the insert you're talking about)?

In the pic on the top right you can enlarge it simply by clicking on it and you will see 2 nuts on the bottom left of the pic and those are what goes into the diff cup as well as the diff top plate.
They are metal inserts that the output spins in, well when I ran my CC 1800kv on 4s the heat that generated in the diff due to the lite oil was enough to melt the nut like notch that holds the nut in place inside the diff cup and the nut was able to spin which opened up the exit hole on the diff cup and this is where my leak was.
It wasn't until I bought a replacement diff cup that I even knew that the diff had such an insert for the output.
Anyone running 4s or higher I would definitely recommend a heavier diff fluid to avoid melting the groove for the output insert.
I don't plan on running 4s but just wanted to see what my 1800 could do in the truck and it was fun.
Hope this helps, good luck!
