OK,
I deserve that one
The rest of the story now. My truck is nice and quiet. 2 hours of labor, real PITA stuff too. These 4X4 trucks have a vacuum system at each wheel which engages the four wheel drive. Used to be, these systems were on the differential hub, but it's different now. When the truck is turned on, a vacuum is created at the wheel which essentially pulls the truck out of four wheel drive. As long as that vacuum holds, the truck stays disengaged and in two wheel drive. When you turn the switch on your dashboard to four wheel, it lets off the vacuum and the wheel engages.
Well, if something happens down at the wheel to interrupt the integrity of that vacuum, the truck will try to engage the wheel. That's what happened to my truck, a vacuum leak. My truck was constantly trying to engage. As soon as the system was repaired and the vacuum was no longer compromised, the wheels stayed disengaged, and the truck got back to normal.
Glad we found it, glad that we could fix it. Not at all happy that this happened at 37K miles with a 35K warranty. Nothing you can do about stuff like this but to eat it and move on but just the same, this is one of those little things in life that make you want to kick something.
Anyway, if or when your trucks start sounding like a tin can full of pebbles, you might remember my saga and maybe this will help some of my KR brothers solve the problem.
Wish you all well,
