Four Wheel Drive
What is entailed in a four wheel drive service? My truck gave me this message the other day.

If it is a GM like my old '04 Tahoe that had the same message, it does NOT mean its time for scheduled maintenance, like transfer case fluid replacement...far from it. It means take it to the dealer for replacement of the transfer case actuator or replacement of the 2WD/4WD/AWD switches on the dash. Hope this helps.
