I am a newbie and just bought my first jeep, a 1985 cj7. When I shfted to 4WD it didn't shift real easy and now I can't get it out of 4WD, ran out of daylight and quit. The jeep has been parked in a garage for the last few years and started but not driven regularly. Am I being overly optimistic in thinking that it might just need to be driven around to get things moving again? If not what is the easiest way to get it out of 4WD?
