Don't turn both lockers on when you're on the pavement. Once both are locked you may find the Jeep is bound up and can barely move. Lockers should only be engaged when you're on an offroad surface, not on pavement. Also, they don't lock immediately, they have to have some rotational difference between the L/R sides before they'll lock as described in post #13 above.Ok thanks. I’m sure it isn’t regeared. It’s bone stock with right at 50k miles. I lifted it on jack stands and verified the lockers engage(all tires spin foward) Thought maybe the diff sensors were bad. I tried Jerry’s solution but was on pavement. I’m not sure if that matters.
The locker light will flash until the lockers are properly engaged at which time it will turn solid. You also have to be in 4Lo before the lockers can be engaged.
