If it's the motor, you might be better off buying a new one as compared to going to a boneyard like I did. They gave me one for a Bronco, assured me it would work, and it didn't. Since I'm so stubborn about taking my vehicles to someone else to work on, I spent many countless hours messing with it, and never could get it to go. Finally took it to a shop and they put a new motor in, and I had 4X4 again.
