Out of no where my console dings at me and the message "Service 4WD" pops up. What does that mean? I've been gone for 8 days and haven't driven the truck in at least 10 days (until yesterday when this happened). I've only offroaded once and it would probably be a 2-3 on a scale of 10. That was even about 3-4 months ago. It popped up yesterday, I put the truck in auto 4wd and back into 2wd with no problems. Today - nothing. My friend said that his truck ('03 chevy z71) did the same thing when he first got it and it never came up again. But now when he tries to put his truck in anything but 2wd you can hear this grinding noise.

Anything I should do or check?
