    I know this sounds like a dumb question, but after i disengage 4x4 and goto 2wd my truck does a quick hop every few feet. Then in drive it makes this chain sound. I have to put it to 4x4, then go back to 2wd to get it to stop making that sound. Someone one tell me how EXACTLY to engage/disengage properly. Its an '88 auto so it has the np208.

    Keep the shiny side up, and the greasy side down.

    If you're going from 4 lo to 2 hi, you need to come to a complete stop, put it in park or nuetral and shift the T-case lever. Then back up about 10 feet or so to make sure it is dis-engaged.
    With my old 208 and manual hubs, if I went from 4 hi or lo into 2 hi, I had to back up a bit before I could unlock the hubs. If you have auto hubs, backing up will also help.

    Usually, you have to back up 10 feet, but on mine I have to back up more for some reason.
