Almost embarresed to asked but I need an answer. I've looked everywhere but I guess the topic is so basic that it doesn't come up. This is my first 4wd. It's a 94. It didn't have the owners manual but it did come with the factory service manual. So it tells me how to tear down the transmission but not how to operate it. Basically what I need to know is the best way to use 4wd. The do's and don'ts. How to engage. The maximum speed in each gear. Any information you could give me or point me in the right direction would be greatly appreciated. I'll post up some pictures of my Jeep when I can.
