eDiff replacement time
To anyone else who has had to have their differential replaced: How long did it take GM to get the part out to your dealer for replacement? I had the metal shavings in the fluid issue. I'm just wondering how long I'll be without. The dealer estimated a little over a week.

occar; Did you have metal shavings in the gear lube, or in the hyd. fluid that powers the E-Diff? How did you discover that you had problems?

They didn't specify which it was, but that they were going to replace the whole assembly.
A few months ago I had a service rear axle warning, and they thought it was an electronic connection issue and showed me a doc about applying dielectric grease to the plug. They did that and the error never recurred. Last week, I found a puddle of what looked and smelled like hydraulic oil under the rear axle area slightly towards the driver's side. I took it in, and during the diagnosis they found the metal shavings and said GM had instructed them to capture the failed assembly, and replace the whole thing.
I can ask which fluid had the shavings in it.

Next time I talk to them, I'll ask which fluid had the metal in it. When I originally took it in, the individual I spoke to wasn't the one who would do the work and I don't think was familiar with the eDiff having both types of fluid, but I am pretty positive that the leaked fluid was hydraulic because it was clear, and had the exact same smell as hydraulic fluid. Now that you've verified where it is located, that also agrees.
That isn't to say though, that the unit couldn't have failed in such a way that put metal in the gear oil, and made the hydraulic oil leak.
There were never any drivability issues at all, but then again it is winter, so it isn't being driven very hard anyway.
