Mine is the 1986 Toyota 4x4 truck I have at my disposal. It doesn't have automatic 4-wheel drive... You gotta go out side, turn the things on your front hubs, then it is ready to go when you put it in gear. I didn't know this, so I was just putting it into 4-wheel, and climbing stuff... Made it with relatively little issue, maybe 4500RPM's to get up a muddy 50 foot bank (fairly steep) When It was pointed out to me that those things had to be turned, I went back out, and was climbing those same hills at about 2200 rpms. Its a tank. I love it.
