    Full time 4 wheel drive

    I was driving my 02 jeep grand cherokee threw some heavy weather about a week ago and tried to use my full time 4 wheel drive setting. I moved the shifter into the correct setting and made sure the Patr time light went off. When I hit the gas, i was still i 4 wheel Part time. No mater if I am moving or sitting still I cant get it in 4 wheel Full time. Please help. Thanks

    Likely a simple adjustment of the shift linkage. Look at the linkage on the transfer case and you'll see a rod passing through the shift arm with a bolt holding the rod in place.

    I am guessing a select trac NV242?

    If so did you try to use 2wd? Sometimes T'cases get 'stuck'* in 4wd - shifting to N or reverse may unload Tcase from the current position .


    *Torque locked would be a good description

    I never understood the "Part Time 4x4 " on my 02 Grand. When i am at home i work part time on things. How does it know to be 4x4 and sometimes 2x4 ?

    part time and 4lo are serious 4wd. Wheels need to slip during turns, so no pavement.

    4wd full time is akin to AWD, the front and rear drive shafts make use of a differential and are not locked.

    Re: Full time 4 wheel drive

    Ok. Sorry it took so long to get back to everyone. I checked everything y'all suggested and nothing worked, so I took it to a Jeep dealer. Turns out that my jeep like to be moving at about 20 mph to move in to 4 we full time. It won't go into it if I'm at a stand still. I can put in in any other position at a stand still but Full Time needs at least 20 mph. So that works now. Thanks for all the suggestions and help. It's nice to have a place to go to for help.
