This may be a simple question to most of you, but I want to make sure I don't tear it up!! I bought an '87 YJ 6 cyl., manual trans (not running when I bought it). I've got it running good, everything works, started driving it around town a little to shake out the bugs. It hasn't been drivable for about a year, so I want to make sure everything is ok before I venture too far. My question is, how do I shift the transfer case? Should I be stopped, rolling, transmission in gear or out? I briefly tried it on loose ground and got rear wheel spin on both sides, but no spin from the front. I'm not sure if I engaged it right. No lights on the dash came on, but this Jeep had wiring issues, so I don't think they work anyways. Any advice would be helpful.
