Toasted 2007 Front Differential
While towing in 2WD, the front diff started "Grunching"(Grinding/Crunching) today. I dont believe towing had anything to do with it.
I have a Floor-Shift FWD, and no locks on the hubs.
The service guy will call me tomorrow to tell me what happened.
Ironically, the noise went away when I shifted into 4-HI.
Does this sound familiar to anybody?

The default setting for the front hubs is in 4x4. That way if there is ever a vacuum leak you will, in theory, still have 4x4 capability. When a vacuum leak occurs it will cause the front hubs to engage. If the leak is small enough the hubs will not fully engage and you will get the grinding sound. Towing has nothing to do with it.

I'd say I had the problem occur about 3-4 times starting at 3000 miles.
