    so today I had to drive through ice. I parked in the parking lot before work. I tried to disengage the 4hi back to 2wd. It did not disengage. However I turned the knob to 4lo and it adjusted to 4lo. I turned the truck off and back on and it was in 2wd. Anyone have any answers?

    I'm not entirely sure what you're saying, but it sounds like you tried to shift from 4hi to 2wd while parked and it wouldn't go? If so, then you'd just need to be moving a bit for it to disengage. When you switched to 4lo then back to 2wd, it managed to get enough jiggering to disengage it is what it sounds like.

    Will it hurt anything if I'm say,, in neutral possibly drifting at .001 mph? Then switch?

    Won't hurt anything. Just a little movement will help it disengage. You can disengage at highway speed if needed too.

    Good practice is to "excercise" the actuator ...I think the manual calls for 10 miles a month. I usually drive a straight road a few miles a week (if I remember) in 4HI.
    4L I will drive a few seconds straight near my driveway...I seem to forget this one a lot. :anonymous:
