Have a Jeep Gladiator Rubicon and wish you could lock the rear diff in 4 Hi? I know I did. Well after some internet sleuthing someone posted the possible answer so I tried it. And guess what? It works!!! Watch to find out how. (Not sure if this only works for 2021 and newer models but give it a try and see. Maybe it will work on JLs too? 🤷‍♂️
