Took my 392 into the dealer on 1/21 to have them install the gears that I purchased online (Yukon complete kits). It took them 2 days to get them installed, but now the rear diff is "locked" because there is apparently an "air gap" that needs adjusted?!?! Apparently Jeep doesn't even make the tool to do that, so they have opened up a "Star" case with the engineers for a solution. The gears are all installed and working properly, but the rear diff is permanently locked. Anyone heard of this?? I know several people on here have replaced gears without issue.
