Rear differential locking automatically and unable to unlock?

[davidlroth]

Has anyone had an issue with their rear differential locking automatically and not being able to turn it off? I was towing a boat and it turned on automatically and now won't turn off. Thanks!

For turning it off, try getting on a very slight incline, put the transfer case in neutral, tranny in neutral, turn off the locker, and let it roll slowly turning the front wheels right and left. If this does not dis-engage the locker, try the same thing going backwards...

It’s locking the rear locker in 2wd? Do you have a Tazer installed?

Yes, locking in 2wd and I have a mini tazer.

Thanks, I'll give it a try, just don't want to damage anything!

That may be the cause. Try unmarrying the Tazer.

My JT is at the dealer now for the dash rear locker light. They found fluid in the actuator. Solution: surprise! replace the whole axle!

mine has been at the dealer for over a week now with same issue. They suspect a short in the wiring harness but have not been able to locate it yet.

Just returned from my Jeep dealer. There is a service memo out on this issue and they will replace the entire rear end. My Gladiator would lock and unlock the rear on it's own. It stared when I was towing a small trailer. According to my dealer, Jeep identified a problem after many complaints. They are behind in producing new rear ends. Go figure !

Just towed a 3000 lb camper from Orlando to upper Michigan and back. Noticed this yesterday and also this morning. I’ve got a Tazer installed also- but it seems like this may be an actual Jeep issue based on what you guys are saying. Are they replacing the whole rear axle or just the differential? Wonder if they’ll just throw a 5:13 in there while they’re at it . I’ll be a nice guy and supply the ring and pinion.

I think there is a replacement sensor available now. Pretty crazy the money wasted in the past replacing the whole axle!

Yea, think the sensor is around $300.

So does one just buy the inline box from Z Automotive to mask the problem or buy the sensor and risk another failure? Hmmmm

Some sensors, the gear lube leaks into them. Causing them to fail. If you read the thread the thread, the sensors are not potted. I did the potting like thread.

I've had 2 in the shop failed full of gear lube. Went the Z Autotive way since there wasn't a fix back then.
