This 2014 Jeep Grand Cherokee V6 runs very nicely at 202k miles...
But it has a concerning LOUD CLUNK/SNAP/POP noise coming from below when doing a hard acceleration from a stop. What's the PROBLEM??

The drive CHAIN inside the one-speed AWD Transfer Case has STRETCHED enough to start JUMPING teeth on the gears!!
Turns out replacing this chain is a fairly straight-forward repair that can be accomplished without removing the transfer case from the vehicle...
