2018 front diff/CV leak

[LVGH]

Here in Las Vegas, the dealers are taking up to eight days to LOOK at a problem. You have to leave it with them the whole time!

I have a fluid leak front diff/CV area, right side. I took a photo before I left it with them. Thought I'd see if this looked familiar to anyone and what it turned out to be??

"Should" be covered under the powertrain warranty.

Looks like a damaged axle shaft seal. Is your truck at factory ride height?

Yes, it is. The dealer replaced the seal. And found a defective IEWS check valve. Apparently resulted in IWES teeth grinding off! They replaced both wheel bearings and IEWS. No indication this was happening! Covered under powertrain warranty.
