Theres a guy I work with and carpool with that has a 2009 GMC Sierra 5.3 and he keeps his 4wd selector switch in "AUTO" 24/7. He now has been having a Grinding sound under his truck that feels and drives like the truck is trying to get into 4wd. Just curious if anybody else keeps their truck in "AUTO" and if anybody has read if any problems may occur.
I have a 2011 6.2 and im trying to prevent this from happening to me. lol
We appreciate the help.
