4Lo stopped working

Was an idiot and became stuck in a a ditch during the snowstorm. Complete stupidity on my part. I was pulled out after by a pickup, but it took a fair amount of effort. At first my 4wd Low was fine, but during the course of pulling me out my front wheels stopped churning. No error messages, but it did lurch a bit at a couple of points. I took it out of 4Lo and put it back in, but it did not help. Always indicated 4Lo. It feels like I only have RWD. I have quadradrive on my 2012 Overland. Did it just overheat, will it reset, or is it likely cooked?

Hard to tell, 4lo is direct coupling I think. Could be broken front axle, front diff, front driveshaft, transfer case chain. I've heard of some that have destroyed a front axle half shaft. But you are going to have to do some troubleshooting. Get under and take a look. If nothing obvious, jack one front wheel off the ground and try to spin it, if you don't notice anything unusual, put it into 4low and try to spin it. You shouldn't be able to turn it.

If you break a front axle, driveshaft the jeep will not move forward unless its in 4lo. If your transfer case is damaged then there should be lights telling you so. I wonder if the brakes overheated from spinning wheels trying to get out?

Thanks for the comments, guys. I drove it about 6 miles after getting out (in snow mode) and no warning lights. I hear no unusual sounds. I just know that only the rear wheels were spinning at the end of the ordeal. I did spin those wheels a lot. I will have to wait until after work to troubleshoot. Like I said - nothing "seems" wrong except I lost the front wheel spin towards the end of the extraction. I was embarrassed all the way around.

Right, I keep forgetting that its only wheel spin that will lock the transfer case... and with a busted axle there will be no wheel spin.

Update. The dealer says the transfer case clutches were worn, and the electronics to shut down the 4wd. This was covered under warranty (the good news). They are replacing the whole transfer case. The bad news is it is on back order and may be 2-3 weeks. In the meantime they cleared the codes and it " may" work. I am driving it until the part arrives. This is the first time I got stuck, and it concerns me that the 4wd failed.

I wouldn't worry about it too much now- you're getting a whole new transfer case! I hope everything works out well for you! Hopefully the weather will be calm while you wait.

Thanks! That is the bright side. And I will be much more careful about how I treat her. I really was an idiot.
