Hi Everyone. Here is an easy question. I just purchased a 1975 Blazer. The transfer case shifter knob offers no explanation on what is what. Can you guys tell me what all the way forward is. 4 Lo? 4 Hi? I played around with it this weekend but did not seem to learn anything other than it can sure make some scary noises. I'm going to go buy a manual on the way home tonight to learn some more. Do I need to be in neutral to get it back to 2x? Or into 4 Lo? Or park? I kept having to turn the truck off to put it back in 2x. With the truck running and I put it or try to put it in park all kinds of grinding noises were going on. Has nice looking warn hubs up front. I got lots of exercise hopping out turning those things.
