My issue is the front driveshaft. It sounded like the starter not disengaging properly, but I hopped under the truck to get a video and noticed the driveshaft issue. I ended up bringing it to the dealer. After some investigating they noticed that the transfer case locks up as part of the start-up process along with all the clicking and popping of the various sensors. Sometimes the transfer case locks and it pops forward a little bit like it's a half a tooth off. I was told that it was "normal" just like everyone else and that it wouldn't hurt the truck.
This was back around the first of the year when I had all this figured out. I ended up bringing the truck back for some other transmission issues (slow shifting 1-2 & 2-3, sometimes a double-shift) and asked about the transfer case issue to see if there was any update. Nothing yet. I was also told that the double-shift was "normal" because a couple other trucks on the lot did the same thing. This is after they admitted there was an issue and replaced the valve body. The dealer was trying to get the transmission replaced under warranty as well but Ram said that it wouldn't fix the issue so they didn't approve it. They sent me home knowing there was an issue and had no solution.
They did tell me that it wouldn't hurt the truck so at least that's a plus (heavy sarcasm intended)... :/
