If 5 (2WD, 4 Part Time, 4 Full Time, N, 4 Lo) then you have a SelecTrac Full Time case. If the handle has 4 positions - no Full Time - then you have the Command Trac case and you should NOT drive on dry pavement in 4 High.

Look at your Jeep and let us know what you have if there are any more questions about 4X4 operation.

Ok, I will look at them will let you know it tomorrow.
Thank you very much!

4hi can be used up to ~55 and switched on/off on the fly by simply lifting your foot off the accelerator momentarily.

4lo is for off roading/mud/crawling and has to be engaged by stopping, place gear shift into N, putting in 4 low, then driving. And you shouldn't go over ~10-15 I think it is...

If there's is an actual mechanical difference internally as far as locking diff's, I don't know

4hi is good enough for all normal driving conditions...

I understand now. Thank you very much.

Yesterday's sound of car , I realized; it couldn't shift to 4lo, it had been on "N".. ooopps.. ( I am a women )
But I learned much more..

Much much appreciated!!!

4 low gives a additional 2.72:1 gear reduction.


Never use part time 4wd or 4 low on dry/wet pavement.The t-case is locked forcing the front and rear driveshafts to turn the same speed no matter what and your geared slightly different in the front and rear diffs so you will get binding even driving in a straight line.No factory lockers in a KJ ever so you will not have to deal that issue untill you add them yourself.

I've never heard of this before however the way you describe it makes since. So what about if I get like 1" of snow?

2wd or if you have the select trac you can use the full time 4wd option.


Buy better tires and you will not need 4wd at all.In 2 winters here in Colorado I have yet to even lock in my front hubs(mine is far different then yours and far from stock) so no 4wd even for 12" of snow.Haven't needed it unless I'm on the trail.

Well I haven't slipped yet in 2wd with command trac. However I do have new tires coming on Monday. And yes I am very aware that you are different from mine. A picture of your jeep is the background on my computer haha

What is better for deep soft sand? 4HI or 4LOW. And what tire pressure? I used 4HI and 16 lbs last time but I felt like I was bogging down a bit especially going from rut to rut. I am also using standard passenger tires (versus the knobby types). The bogging down may have been my fault as I was very nervous so I may not have been accelerating properly or staying in the right ruts. This was my first go at off road and the ruts were huge leading me to believe the sand was very deep.

When off-roading in sand, mud, etc. most use 4-LO. However, often when running on sand such as on the beach you like to get up to speed - and 4-LO should only run up to about 15mph. Any faster than that and you're turning some serious RPM's.

Work on your technique a bit more. As you said it could be the acceleration and use of the throttle that caused the Jeep to bog down vs being in the correct TC range.

thanks for the info. Going out again this weekend so maybe with time I'll become more confident. I love my Jeep but as it is my first one, I have no idea what I can do with it yet. Friends tell me that I can really dish out the punishment but I guess until I try something and see I can for myself, then I wont believe it. I'm really looking forward to when I can go mudding and get her really dirty.
