'07 Rubicon, Lockers won't disengage... stranded

We've been having problems with the lockers on the Rubi, and now he's stuck at the ORV park, since the fronts won't disengage. Any assistance is greatly appreciated. He's done everything the manual says, still flashing. Had problems with it yesterday as well. Thanks for your help.

Do you have the 4-hi bypass installed and have you replaced the locker sensor lately or changed for fluid. Did you try to pull the air line off the top of the diff the pump may be running all the time for some reason. I know sometimes it takes a bit of driving around to get mine to disengage sometimes.

JK lockers are electric, not air.

They engage fine, but won't disengage. He spent a few hours fighting with it yesterday. Finally after taking it through a nice puddle it disengaged. Now he went out again today, and locked them, and they are stuck again. He's afraid to try and drive it home, cold, tired and frustrated. We haven't even made the first payment on it yet...

Try this--4LO, reverse--2/3 mph--neutral--TOUCH TOP of locker sw-dash light should goout-

If the rear light still flashes--do the same then TOUCH BOTTOM of locker sw.

i HAD TO DO THAT WHEN MINE WAS NEW--NOT NOW-

Good luck

Has not been modded. He did all those things and it still won't unlock. He's in 2WD, had it up to 50mph.... Still locked.

How do you know they're LOCKED, is it hard to sharp turn ??

Do a quick one wheel lift (jack) and see if it's actually free --don't trust the lights !!

I'm guessing that it's not locked and you have a faulty switch.

You can tell by the way it turns they're still locked. Of course it's out of warranty...

He managed to limp it home, and I guess it'll go to the dealer tomorrow...

Hey folks. Thanks for the input. I appreciate your willingness to help however, if you've ever driven with your lockers engaged you know there's no mistaking the fact they're locked. It's not a faulty switch or light.

As an FYI, starting completely unlocked, pushing the bottom of the axle lock button once will engage the rear, once more will engage the front, more pushes on the bottom will toggle the front on and off. To disengage both, push the top of the button.

My rear locker will lock and unlock very easily. The front, once locked, will not unlock, whether it be by using the bottom of the button to leave the rear locked or by pressing the top of the button to disengage both. I've driven fwd and back many times and being in 4lo, 4hi, 2hi but to no avail. Locker remains locked.

I'm looking for a relay thinking maybe I have a bad one but so far, I've only located a fuse that controls the power to the lockers, no relay. Anyone know of a relay and where it's located?

Thanks. At this point, I think I'd rather it stay locked so the techs at the dealer can see the problem first hand.

Out of warranty? Don't do it, then. Dealers are bad. Find a mechanic who could part a diff. Actually you can easily disengage the locker yourself. Just drain the fluid, take the cover off, and you'll see the locker ring. Use some kind of hard plastic piece to move it. You may also see visually what's broken. Once it's free, cover back on RTV, refill, and drive it to a mechanic who you trust.

I have nothing useful to add to this thread but it has left me with few questions. Hopefully I won't get flamed too bad for asking.

But..... what are lockers? Is it something on all Jeeps? How would I use them and why would I want to? And what is it about them being stuck that is so bad.

Yes. I'm new.

You might be able to find some information on JK-F. Try posting the same question there. It's a much bigger forum. Here are a couple threads I found that you might find useful.

Help! Rear locker won't disengage.

Got My Rear Locker Fixed Under Warranty!!

Yes. I'm new.

Lockers do exactly what the name implies, they lock your differential into gear. Most vehicles with spider gears allow the same amount of power to be transfered to both wheels on an axle, but once terrain changes for one wheel to the other, if any slipping occurs one wheel is allowed to spin faster than the other, to prevent this, lockers lock the gears in the dif into place by either using compressed air, electronic solenoids, or a cable, once this is locked, both wheels spin in unison creating the ultimate in tractions. Unless you are gonna be doing some heavy offroading in your jeep, I wouldn't get them, its just a waste of your money, your jeep is more than capable without them, and you should learn the basics of trail riding, before you worry about getting lockers. Wheel placement, power adjustment, gearing, and braking are very basic concepts that need to be learned before you worry about putting advanced equipment on your rig. I have a sport jk with no lockers, and I can keep up with my buddies rubicon even when hes locked in because I spent over 4 years in the marine corps learning basically how to offroad properly in humvees, seven tons, and the lvs. In the end an experienced driver is what makes the difference.

Greaaaaaat. Heard from the dealer today. The actuator is toast, bits and pieces I think he said. One week for parts to come in, $2800 p/l. Hopefully the aftermarket warranty will cover it... this is on a Jeep we haven't even made the first payment on....

Umm, you need to check your states lemon laws. This is an extremely expensive fix, and if you haven't even made a payment yet, I would be taking that thing back to the dealer you bought it from and demanding that they fix it free of charge, or atleast give you the parts for free.

so lockers are an switch activated, interaxle differential lock? im gunna guess my 2010 Sahara unlimited dosent have that, and 4wd just means there is power to all 4 wheels but turn independly unless you activate the lockers.

and while were at it there is a switch on the dash with a jeep on it and 2 squigglie lines underneth, can you clear up what that is... i checked the manual, i mean dvd and it was clear as mudd...

did i say im new... please dont flame me to bad

Your Sahara does not have factory lockers. Only the Rubicon has those. That button you are talking about is most likely the traction control button. You'll want to turn that off before doing any offroad activities.

I'm pretty sure lemon laws don't apply to used vehicles. That being said, if you have a good dealer they may fix it since you didn't get a chance to get it out when you bought it. I few years ago we bought a used Ford Explorer from a local used car dealer in January. we didn't buy any warranty so it only had the standard 30 days. In June when we tried to use the AC, it only blew warm air. The dealer had us take it to his mechanic to get checked out. It ended up needing a new compressor and they fixed it free of charge for us.

In simplified terms, 2WD is really 1WD and 4WD is really 2WD, one front, one rear. When the axles are locked you have true 4WD.

Well, you know how it goes when you buy used..... It's at the dealer we bought it from. But our 30 day/1000mi dealer warranty was up about 300 miles and 3 days before we had an issue.... It'll be alright I think If we get the warranty stuff straightened out. It's a really good warranty, covers everything, but wear parts....

I told you not to go to the dealer. They always fleece people like that. And it's not like they are evil or anything, just lazy and incompetent. I remember I had a knock on Chrysler 2.0L engine. Dealer's offer was to replace the engine for $4000. A great deal for engine swap! But did I need it? No! It was a bad hydrolic lifter adjuster. That $2800 you get is a rebuild of the axle they the do just so the monkeys doing it do not need to think.
