Jeep Stuck / Wheels Not Turning

So I got my 95 yj stuck in a very little bit of mud this morning.

I had it pulled out and one of the rear wheels wasn't spinning in neutral as it was pulled out. I tried playing with the transfer case, now, the left rear which wasn't spinning now is free and the right rear won't spin.

I have a posi-lock installed, but don't really know if its working. Also, I was in 4 hi and 4 lo to try to get out of the mud and I didn't feel any pull from the front wheels.

Can anybody help with why one of the rear wheels won't spin, then starts spinning and the other stops?


Thanks!

So if I'm reading this right, as the other guy was pulling you out of the mud you had the transmission in neutral and one tire was rolling and the other one was locked up and skidding? The e-brake was off and your foot was off the brakes right?
If so it sounds like your "posi" may be damaged but you'll need to jack up the rear end and start testing your rearend and gear boxes.
Do you know to test these?

Yes you are correct.

I managed to pull it out and she drives normal. Maybe I don't get what the posi lok does.

My understanding was that it replaced the vacuum actuator for the front wheels.

I can never really tell if the 4wd is working...this is my first yj and I've only had it a few months.

You should feel a big difference in the way it drives from 2wd to 4wd. Enjoy your YJ!!

Man if I am reading this right you are off base a little on understanding how 4wd works. By installing the posi-loc cable in the front you only repaired the problematic vacuum accuator to engauge the front differential.
As far as the rear, this has nothing to do with it. You sound like you have an "open" carrier which is normal. When one tire gets resistance the other will spin free. If both have the same amount of resistence they will both spin. This is the same for the front carrier/differential.

You need to install a locker in the rear or a good limited slip to get both tires to spin at the same time. I welded mine, but I would not recommend doing so on a daily driver. I drive mine more off-road.
I sure hope this helps you.
