i have a 93 grand cherokee laredo 4x4 with the 4.0 straight 6 in it. and i have no clue how to work the 4 wheel drive. i know it has part time 4 wheel which i don't know what wether thats all wheel or four wheel. two wheel i know how to use of course and i really have no need for 4 low. but when i switch to 4 wheel it makes god awful noise and doesn't feel like it's pulling. then when i switch back to 2 wheel it wont go back in till i stop put it in park let it sit and then go. i also see that it has a full time 4 wheel but i cant figure out how to get it to go in it. i know little to nothing this is my first vehicle and 4x4 by default so i'm tryna learn so if you can answer or help thank you
I see your new here. Welcome to the world of Jeeps!
Friendly advice, the search function and a little bit of grammar goes a long way here.
That being said, I believe you have the 249 t-case, and I also believe it's a "shift of the fly" style. Meaning you shouldn't have to be in park, neutral or have your foot on the brake. You can switch while in drive, and going about 3-5 mph. Sometimes it takes a pretty hard yank on the shifter to get it into gear, and you may hear some god-awful
grinding of the gears. A little bit isn't to bad, you'll learn where to shift it just like a manual transmission, because it's a manual 4wd. Sometimes they need a little bit of "coarsening" to get them where you want it. Try it with your door open and ear pointed to the ground and listen to it engage and disengage.
This ought to help as well:
4wd full time
: Wet or snow covered roads, daily driving basically.
4wd part time
: Offroad use only! Loose dirt, rocks or mud. Do not drive on dry or grippy surfaces because your axles are locked together. (Search "crow-hop" for more info)
: Provides lower torque to the wheels for better traction i.e. climbing an ice covered hill. DO NOT
spin your wheels in 4lo ever. Downshift your transmission to 1 or 1-2 (idk the ZJ too well) to prevent revving the engine to high.
Hoped this is what you we're looking for, happy trails!
