new owner problem with 4wd

bigd · **Posted:** Thu Aug 16, 2012 11:43 pm

I just picked up an 03 4x4 with 118k miles on it. I got it home and wanted to make sure 4wd worked so I shifted to 4 part time and got a nice loud bang every 10 feet try it in full time and the same thing. So I go to shift it back to 2wd and the shifter cable comes off the transfer case. Any way I get it back on and it seems to be stuck in part time 4wd or just the light is on anyway. After looking closer I notice it has a size smaller tires on the front wheels, im guessing this is what was making it bind and go bang. Any way looking for ideas on what to do now, I dont know if I want to try to drive it and see if it will snap back into 2wd but I need to get it to a tire shop to get new tires on it, looking for ideas.

For what problem, for the 4x4 light staying on when in 2?? Or issues shifting? If the tires aren't the correct size, you should be able to shift it back into 2, put the transmission in neutral and then there should be no problem shifting the tcase, especially if you're moving slowly like just letting the brakes go when on a down-hill.

If you know you're in 2 and the 4x4 light is on, and then it goes off when in 4, it's the sensor, kinda a pita to get to, have to take the console bezel out. search, you'll find how.

If you're sure the shifter put the transfer case back in 2WD - and you have the SelecTrac Full Time transfer case - it will eventually shift back into 2WD, but you'll have some issues with binding, banging, etc. till then. Best advice is to shift back and forth from Drive to Neutral to Reverse and slowly move the Jeep forward and back. That should release the t-case into 2WD.

The SelecTrac is sensitive to tire size. If you're getting new tires get four new ones instead of trying to match two new ones to the two you want to keep. Even a few 32nds of an inch will be a problem. And once you get a matching set on your Jeep rotate them religiously to keep them consistent.
