I’m having trouble getting my turf/2wd/4wd to work correctly. I have adjusted the box under the bed according to pages in manual and advice here. I either have turf or 4wd diff lock. No 2wd lock or 4wd. The display on dash never changes from turf. In park it locks the rear diff together but if you put in High 2wd it still is in turf. I have checked the little rod end under hood and it’s tight and attached. What do I need to do next? Machine is a 2016 with 500 miles on it. 8f0b0de0354a3e8a70f2da2952391e3a.jpg
