When I first discovered that my front axle wasn’t engaging I started researching and decided that the Posi-Lock was my answer. I posted up the question here and got some great information. Had I ever encountered a situation in my almost fifty years of driving wherein I’d have had the want for 2-Lo I’d have been all over this actuator. But in scanning my dusty brain files I found that topic to be missing so I opted for the stepper motor actuator.I installed the Posi-lock cable assy many years ago in my '88 1500. It was adjusted correctly the first-time and still works to this day. I love it for the exact reason as was described earlier. 2wd low range!
For the little winter plowing I did before I upgraded vehicles, I'd leave the front axle connected, and floor shift into 2wd, drive to the next driveway, throw the floor lever and have instant 4x4 again. No waiting, even for later model electric worm gear activation.
4x4 Posi-lock: best operating front actuator ever!
