Thanks John!

and just like the original poster, this morning it went back into 2x4 just fine after a rest over night.

The weird thing is that I went in and out of 4x4 four or five times yesterday and it was on the last trip off the beach that it got stuck.

This problem happened the past two times in the past year and I only went into 4x4 for a short amount of time so yesterday's all day transferring back and forth was weird.

For as cheap as the switch is I should just get it and when I crawl under the jeep to check it out I can replace it while I'm there.

I've heard of the PosiLock mod but don't know much about it ..... but looks like a more involved thing to do and right now just want it working again. It's been limiting my time out on the beach!

btw, I got a 1997 Jeep Grand Cherokee Laredo 4.0 liter straight 6 cyl with Select Track
