Differential/Rear Axle Leak? Anyone else? Thoughts?

[dhrandy]

Looks to be a leak at the differential/rear axle. But… I don’t see any indication of drips. Any thoughts? Haven’t taken it to the dealer yet. I saw it a few months back and then forgot about it.

Definitely a seep of some kind. But I'm guessing it's very light since it's too slow to drip, and is only migrating by osmosis.

The entire quantity that has escaped could be as little as a 1/4 teaspoon, if you know what I mean?

Spray some fluid film on it to blend it in and be thankful you have good rust prevention. That’s a weep, you’re not low on fluid, and the axle tube is pressed into the pumpkin. You’ll need a new rear axle to correct it, and I can’t imagine Ford will pony up for one unless there ends up being measurable fluid loss.

I have the exact amount of fluid at the exact location. Truck is at the dealer getting unrelated issues fixed and I was told that the rear diff is not leaking. When asked where the fluid is coming from I was told its normal. Truck is still under warranty so its normal, I should have them evaluate it for a trade in and when they ding me on price because of it we will see how normal it is.

Relative who is mechanic said that its normal and to enjoy the rust preventative.

i will just ignore it I guess
