This one was a warranty replacement with 40k miles on it. The original lasted nearly 100k miles before failing at the same spot. In my opinion, this sort of failure should be one in a million. Of course, chassis attachment points for subframes should last forever as well but we all know how those turn out.
It took us 4 hours to pull the truck into place on a sloped driveway, jack it up, pull/remove everything that was in the way, drop the transfer case, and open it up on the bench. We will probably replace the chain and all the bearings and seals while we are in there.
