    Hi all 4wd gurus out there. I have a problem with my Jimmy 1986, the 4wd will not engage, and I dont know how to
    troubleshoot this problem. The transfer case is NP208, and
    I think that the output shaft from the transfer case is not spinning. I have manual hubs, and they are locked.
    Is the 208 blown ? or is this a simple thing to fix or test.

    Thanks in advance

    Get underneath and grab it....see if you can turn it. If you can turn it something isn't engaged...check your hubs...make sure they are locked. Make sure that you didn't accidentally put the T-case in N instead of 4H...I think you would have found that already but ya never know. Thats all the help I can give right now...never done major thingys like that.....YET!!!

    Check your fluid level and linkage adjustment.

    Place shift lever in 4 HI
    Push lower shift lever forward against the 4 HI stop
    Place rod swivel in shift lever hole
    Hang a .200-inch thick gage tool behind the swivel
    Run the rod nut (A) up against the gage w/the shifter against the 4 HI stop.
    Remove the gage and push swivel rearward against the rod nut
    Run front ord nut (B) against the swivel and tighten secureely.
