rear diff question

I was changing the oil in my rear end and noticed that it looks like it got hot sometime. My question is is this normal and what would have cause it if its not normal?

I don't think there is anything wrong... It looks like it was heated with a torch or it a heat mark from tempering? I notice the heat mark is only on the one part. The second part is if that was truely getting hot it would have scorched oil burnt to the part (blackened).

As long as you have no metal in the bottom of the pumpkin... I won't worry much.

If you ever get stuck, and try really hard to get out, and the LSD won't work (or if you don't have it), it over works the side gears in the diff.

Well of course because one tire is spinning twice as fast as it should. If you get stuck your gears should be the least of your concern, it should be your transmission if it's automatic. Automatics like to bind when going from Foward to Reverse constantly and quickly.
