The 4-wheel drive is not working. The drive shaft part of it is going around. The fuse for the 4 wheel drive keeps blowing. I was wondering if you could tell me what to do to fix it? Thanks Gary

I got mine fixed. It was the actuator. I guess it is a real common problem. It goes in the front axel. The way I understand it is there is a heating coil in there that heats the fluid up and pushes the actuator in to put it in 4-wheel drive. It cost me around 100.00 dollars for the actuator and I put it in myself. It is easy to do. It just srews in the front axle. GG
