77 cj5 4spd v8 I’ve posted several times about how My Jeep is stuck in low gear. Sunday i have a friend coming over with a goal of figuring out what’s going on. Attached below are pictures of my transfer case. Can you tell me which side controls low/high and 2/4? https://photos.app.goo.gl/kEBRJeBNReTSU3op8 how tight should the linkage be? Where it connects at the two bolts? https://photos.app.goo.gl/7GvhtdGW8Laf6GRH7 Any tricks I should try. There looks to be a vacuum hose on the driver size, what purpose does that serve? https://photos.app.goo.gl/NJZAQGV4ggcFWq9y7 I don’t know where to look for identification numbers.
