Hey everyone, first thing first I want to say that this site is very cool and very well put together. Ok now to my question. Im 16 and am looking for a car. Now I found a '92 s10 blazer v6 4.3L 4x4 and the guy wants 3k for it. Its in very good condition and all. The things is it has cv joints in the front, for the 4x4. Now the car has only 68,000 miles on it and, like I said, is in very good condition. Now Im not sure how the 4x4 locks in and all and whether or not the cv joints has so many miles or what. I guess the question I have is whether or not the cv joints are always spinning, or are they just spinning and being worked only when the 4x4 is engaged. Besides that the only other thing that needs attention is the heater core. I believe that it is leaking but I cant be sure. Its disconnected right now. Im not really worried about it though, I can live without for a while. If anyone can help me with the cv joints that would be great. Also If anyone knows of any other problems with that line I should be aware of that would be awesome if you could tell me. Thanks in advance for all the help. Here is a pic.
