Hey, I have a 2014 1500 with the 5.3. I have started hearing a clucking noise from under the truck. I went into a parking lot and tried it in many different ways, but what I have narrowed it down to is the transfer case. Truck is in reverse and in auto 4wd with the front wheels straight or turned (hear way more turned). It is a loud clunking noise i thought at first it was the rear differential. But digging into it more I think its the transfer case. Any help would be greatly appreciated.
