"check 4x4" warning
 

Apparently I cannot use the search function properly so I'm bringing it up, if again, my apologies...

My 2011 f150 ecoboost fx4 just gave me this warning on my way home. It had just begun to rain and the streets were slick so I put it in 4 high.

When I went to switch back to 2wd, I get the warning on the dash. WTH?! I just turned 70k miles on it and everything needs work. I have had all the gearboxes serviced and maintained it according to the book.

I will say that I noticed somewhat of a whine on the passenger side in 4wd.
