Finally addressed the rust on the differential housing, did not even try the front driveshafts, wanted to see how this worked out. Corroseal. Including prep I spent maybe an hour.

I also discovered (i have the metal pan/plug on a 2018) that the Raptor's oil doesn't have one drain. Well maybe one main but there are several auxiliary drips to deal with. I made a bigger mess with a simple oil change that I ever expected.

Went ahead and emptied the catch-can at ~6,500 miles. Was maybe 0.75 inches deep, looked like all oil as in not drops floating on water. But when I dumped it there was a layer of milky muck at the bottom. Just glad that isn't in my intake/valve-train.
