I'm in Wyoming. Winter is kicking my ***. My 4wd is not working. Truck has 7000 miles on it. Dealership is closed tomorrow and I need 4wd tomorrow. I'm headed up a mountain with a 27 ft enclosed trailer. No way 2wd will cut it. The truck has manual shift transfer case. The lever will not budge from 2wd. I have pulled quite hard on the lever and I don't want to break it. I tried shifting while driving forward, reverse and neutral. I crawled under the truck and checked the linkage out. Looks perfect. No rust or snow or ice. I sprayed all the linkage with penetrating oil about 10 min ago. I figured I would let it set for the night and give it a try.
