Gang,
Here is the 2nd UOA on the front axle on my FX4. No surprises to be found (other than Castrol seems to be a decent oil--haha). Amsoil 75W-110 went into the axle this time (to match the Amsoil 75W-140 in the rear axle).
Below are Blackstone's comments; thoughts and comments are welcome!
We didn't find any moisture in this sample from your front diff, so it looks like going through the water didn't hurt anything. Wear metals look great, especially for such a long oil run. Universal averages show typical wear levels for a Ford differential after about 44,200 miles on the oil. Insolubles are nice and low at 0.1%. The TAN read 6.0, showing some acidity, but again, that's from the phosphorus additive and not a concern. Nice report at 80,300 miles.
