This is the third issue I'm having with my Jeep. I can transfer the truck into 4x4 but when I shift back to 2x4 nothing happens, it remains in 4x4. When I leave the shifter in 2x4 and park it for the night, in the morning it drives in 2x4. All fluids are good; the guy at the parts store said that because I have the Select Trak its probably electrical. Any thoughts on how I should proceed.

thanks

How about if you just shut off the engine after shifting it to 2x4, ait a couple of minutes, and then start it up right away? Is it in 2x4 then?

that does not work; I've tried that and it remains in 4x4, it has to sit for a while. Example, if I go shopping and come out an hour later it will shift back to 2x4. It seems that it goes back to 2x4 when it cools down.

I'm not sure it's the "cooling down" that is the operative factor.

If you have a vacuum connect/disconnect mechanism for the front axle, I suspect the problem lies there. It may be that the vacuum release route is plugged/blocked, and it takes sitting for an extended period of time for the vacujum to leak down.

There is an easy way to find out. Remove the front drive shaft. Put it in 4x4 and move a few feet. then put it back in 2x4 and shut off the engine. Get under the Jeep and see if you can turn the front yoke on the t-case by hand. If you can't, then it's something in the t-case, not the front axle.

Couple of things could be the issue. First are you shifting the transmission into neutral BEFORE you shift out of 4wd... I know you have the select trac and it's supposed to be a "shift on the fly" t-case but from my experience that is rarely the case. I find that when I put the transmission into neutral and then shift out of 4wd it will go into 2wd way easier than shifting it on the fly or while in drive. Secondly you might try checking out the t-case linkage as it is a pretty flimsy design and prone to wearing out and having "slop" that would not allow t-case to shift properly, and on a 10+ year old vehicle that is probably more than likely the case. Just crawl under the jeep and you'll see the linkage by the t-case and there is a screw that allows you to adjust it fairly easily. Adjust it a bit at a time until you have a clean, firm shift from range to range. Hope this helps. <img src="/forums/images/graemlins/cheers.gif" alt="" />

hi there have a big prob, ,i have a jeep grand cherokee lerado 2.5 td 1997,,let me go back to the start,i noticed when i turned left or right in 4 wheel drive on take off it bineds and jumps also sounds like teeth jamming all this is loud , so i took front diff half shafts and checked all at front OK i too the tans case apart the large silector was worn so i re placedit for new all the rest looks good ,also tried it in the mud and that still dose it but not as bad ,i was thinking it could be thechain in the trans box ,can any one help thanks paul <img src="/forums/images/graemlins/confused.gif" alt="" />

PAUL All you typed is NORMAL!! When turning all 4 wheels turn in a different circle. So one or more MUST slide to get the axles turning at the same speed.
What you learned is to NEVER use 4x4 on dry hard streets. The result can be disaster and permanent.
When on slick or muddy ground the tires slide as they are supposed to and you don't feel the binding but they are still doing the same thing they do on dry hard streets.
When thinking of purchaseing a 4x4 my test to see if the thing is working is to go to a parking lot and put it in 4 wheel and turn in a tight circle.. If it DON'T jump and hump I know it doesn't work!!

many thanks ,it sounds so bad when it is doing it ,so can you tell me what and were is all the noise comming from ex..please i wiould like to no ,as i have put a lot of time in to this ,many thanks again paul

hi again big jim ,if you put it in the part wheel drive half way on the shift leaver will it do the same thing ,thanks again paul

I don't think the part time will do the bad thing.. When I put my ride in 4 a light comes on the dash that says part time..or something like that. Then when the tires start slipping the light says 4X4..
As for the noise, what is happening is the drive shafts are turning at the same speed. They EXPECT the front end and the rear end to also turn at the same speed.. In a straight line this MAY happen. However when making a turn...even a small one.. the front end travels futher than the back end does.
So the driveshafts are still turning the same but they are encountering a huge resistance (on dry pavement) this restance causes the tires to attempt to slide, and a big strain on the axel gears. Then suddenly the strain overcomes the grip the tires have on the pavement and the vehicle lurches forward... at the same time the ring and pinion which ahs been twisting on one direction gets such a big release the gears CLANK together in the opposite direction of the one they had been pressureing against.
I'm sure there are other noises but the gears are the biggie.
