be aware of another issue...Jeep changed the transfer case linkage a few years ago (I have A 2011) it is now a CABLE with nylon bushings that have molded nylon fingers holding the cable to the shifter levers... these fingers break off, the cable slips off the linkage levers, and you can't shift the transfer case....Jeep has an upgrade kit (that is as close to admitting a design flaw as they will likely come)that "fixes" the issue.... I found out by mine failing, leaving my transfer case in neutral....fortunately, I'm still covered under towing & powertrain warranty.......BUT they only fix the end that broke!!!!!!!
