Thank you! I didn't see any shavings on the rear differential plug, but I'm not sure if that one is magnetic. When my son gets home this evening, he'll check. I'll also video from the outside while he drives in a parking lot. That's the best way to hear the sound. It didn't work when I tried recording while driving with the window open. It may be tonight or tomorrow morning before I can get a video, depending on how late he works this evening.
The front differential fluid was black and the plug was full of metal bits. I read that when it's that bad, to change it each week or so with inexpensive fluid until it cleans up, and then use good synthetic oil.
