I changed the rear Differential oil. I couldn't get one of the bolts off so the "Pumpkin" plate stayed on. I may be changing it more than I thought because of that. The old oil looked like used engine oil, but it was not like the Transmission fluid.

On another subject, while I was working on the car I heard a racket outside on the street. Someone was driving a vehicle which looked like a Suburban; He/she went by and the car was squeaking and there was some sort of overheating going on which didn't come from the tailpipe (it wasn't burning oil) so I wonder if it was a stuck brake or if he was cooking his differential. It would be a bit funny if it was the rear differential out of oil, considering what I was doing. It slowed down and stopped as the car did, so I don't think it was a lack of engine coolant.
