Fix the Faulty Locker Sensors in the Wrangler JL Rubicon and Gladiator JT Rubicon

[@luky61]

Just installed in both front and rear. 5 min install and it worked as described. Dealer took 4 different attempts and never fixed the issue. Decided to just do it myself. Thanks for the great product.

[@travismartin11-22-2013]

Thank you for coming up with a great fix for this issue, Jeep is still working on it late 2022...

[@huntinbob06]

I just installed this on my 2019 JLUR with the rear locker flashing on my dash. The flashing went away and the locker works just fine. Thank you for the fix. I'll be buying another one for my front locker, (just in case) since I regeared to 4:88s 4 years ago.

[@historyj1444]

Thanks for the excellent customer service and video. My local Jeep dealership wanted me to replace the entire rear axle assembly with a backorder time of 4 months. I guess their idiocy to redesign a simple sensor is your gain. Lol.

Axle Sensor Kit - Mopar (68544629AA) now out but will prob fail again.

[@TealOxAdv]

Great video. Love your products. We recently purchased a Rubicon and will be putting one in our glove box.

[@zautomotive]

Good choice! And thank you

[@johnnychaffin307]

Just installed this on my 2018 JLU. Works great. five minute install.

[@shockerracing]

This is great news! I just got the light on our Neon Gladiator and the MojitoJeep has had an intermittent Service Axle Locker Light.

[@jesusjuice7592]

I have this issue not sure if its my front or rear axle so I just purchased 2 from your website. so I wont have to worry about it. Thanks for the install video to make it easy and quick to install

[@jesusjuice7592]

@@zautomotive Update, it ended up being my front lockers sensor that is the issue, even with this plugged in, I had to remove the bad sensor; drill holes into the sensor in 3 places, fill it up with electric sealant than reinstall. I was hopping this was going to bypass the sensor that was faulting. Still a good product

[@MrTurbo64]

Just removed the rear oil filled sensor, drilled 3 holes in plastic sensor body, cleaned out with electronics cleaner then potted the sensor. Cleaned steel fuzz off sensor magnet, added fresh Valvoline 75w140....no more "ding" or "service axle locker" message. Cost about $55. For two quarts of gear oil and potting epoxy to fix and jlur needed differential servicing anyway.

[@zautomotive]

@@MrTurbo64 great… plenty of people that don’t want to do that though

Is this the same as the SEV 4WD, I just got that on my 2020 Gladiator and I haven't been off road.

[@GREYWOLF_JL18]

If there actual locker problem will this notify you or is this bypass and no longer tell you of actual mechanical problem?

I have the same question Any help Z Automotive?

[@brandonke690]

2023 jeep Rubicon with 26k miles on it and 4.88 gears, just had this happen to me over the weekend. Waiting for the part to come in so I can fix it, Might end up potting them also just not sure yet.

[@303Estates]

great video!! What happens if you just unplug current plug ? I imagine lockers will not work, but will light go out?

[@zautomotive]

Would contact support before you just unplugged the OEM lockers - [e-mail]

May have something actually failing with the lockers, should get it checked out. Email support at [e-mail] and they will be able to recommend the next best course of action

[@ut_punkn1859]

Damn 179 for one bypass harness. Why does it not come with 2.

[@lachumbley]

1 bypass is HALF the price of 1 sensor!

[@FunkyELF]

I have an '18 Rubicon. Had my rear axle replaced in '21. Now I'm getting the message again. They now sell sensor separately (actually a kit of 5 different sensors because apparently only 1 works? That's what the parts department told me). Anyway... I'm leaning towards buying this Z Locker OEM but watching this video I'm concerned now. He mentions that it could be due to metal shavings in my differential? Maybe I shouldn't simply put this thing on which will ignore the issue.... should I get out fluid checked out?

[@zautomotive]

If you're concerned get it checked

[@Labyrnthdom]

I bought 2 of these. It did not fix the issue. So im guessing it is really broken. The company did give feedback and good troubleshooting to try. Im not disappointed in the product. Im disappointed it didnt fix my front locker problem. Also on Uconnect screen on the radio. It shows both lockers locked. But they are not. If they was you can tell by gling slow in a circle.

[@zautomotive]

@@Labyrnthdom did you end up going to the dealership, what did they say the issue was? If it was one of the issues with the codes mentioned in the video, the bypass won’t work; curious what’s going on with your lockers

[@ridgecamper18]

I have the common issue and intalled the Tazer bypass wire and it permanently brings up the service locker light on dash? Do i have a wrong setting on the Tazer or some unkowen issue?

[@zautomotive]

Have you tried on both front and rear? You could also read the error codes through the TaZer as shown in the video, to see which locker is throwing the codes

[@eddygtv7105]

Im getting “service axle locker system “ on my TRX . Will this solve the issue ? It pop up when I hit a big bump then goes away after 3 secs

[@zautomotive]

@@eddygtv7105 the Z-Locker is not currently compatible with the TRX but you can email support to see if they can assist in any way - [e-mail]

[@fernandobarba998]

What do you suggest doing if my 2018 wrangler JL only has the flashing locker with exclamation point. It hasn’t changed to a steady symbol.

[@zautomotive]

Buy the Z-Locker because that’s the initial sign that they’re going bad. Feel free to email support for further clarification- [e-mail]

[@fernandobarba998]

Should I purchase front and rear?

[@zautomotive]

@@fernandobarba998 as the video says, best thing to do would be to read the codes to determine which one is going out. If there is no codes, you can buy one and install it in one place to see if the light goes away. If it doesn’t, move it to the other location and see then

[@АлексейизБрянска]

Hello. Thank you very much for this video. Could you answer a couple of questions for me. Some time ago, I had this problem on my JL Rubicon. At first the error appeared and disappeared, later it began to glow all the time on the dashboard. I purchased your OEM Z Locker and installed it. But I installed it on the front axle of the car and the problem disappeared. The error did not reappear for several weeks. Now the same error has started appearing and disappearing again. I do not understand? I installed Z Locker OEM on the front axle and it should be fine. Does this mean that now I have the same problem with the rear axle and I also need to install Z Locker OEM on it? Does it happen that 2 sensors fail at the same time? I also have a Tazer mini - but it doesn't find any errors. And the last question - when will Z Locker OEM be available to order? Once again, thank you very much for the video and for such a great solution to the problem.

[@АлексейизБрянска]

@@zautomotive, Thank you very much for the answer. I also thought so, that this is due to the fact that the error is not active all the time at the moment. I had 2 errors: B23BB and B23BF, but I understand this is not related to my problem? But in any case, I think I'll still get your second device.

[@АлексейизБрянска]

@@zautomotive, yes, it's a really great job. My respect to you!

[@АлексейизБрянска]

Hello again, my friend. I have a problem again. If you remember the last time I bought your device, but it didn't solve my problem. The blocking error still sometimes appeared and disappeared. Now I have bought your second device. I have your devices installed in front and back. But, the error still appears and disappears. Sometimes it happens every 10 seconds. Tazer mini did not find any errors. I do not know what to do...?

[@АлексейизБрянска]

@@zautomotive , спасибо за ответ. Да, наверно так и сделаю. Разве что, сейчас, в это непростое время - Это сложно. Извините…

[@brucedemarest3929]

They really should include instructions with these parts. I installed on rear axle, no change. So I took it off and put it on the front axle...still no change EXCEPT now I'm getting g a "SERV 4WD" light (solid). How screwed am I?

[@zautomotive]

I'm confused, you're commenting on the video that is the instructions... As mentioned in the video, if you have the TaZer you can read the codes and see which axle is having the problem.

[@johnkraft5640]

This system can be installed and left permanently? I assume you can Install for preventive measures as well. Appreciate any information. I have zero issues at this time. I can only assume this will eventually happen no matter what, and the only way to combat this situation is to change the rear dif fluid often or purchase this product and change the rear dif fluid when prescribed in the manual.

[@zautomotive]

Correct, it can left in permanently, or as many people have mentioned to us, they just leave it in their glove compartment and have installed it when needed. Also, as mentioned in the video, if the Jeep does end up having a locker issue, you can use the tazer to read the code and determine which locker is having the fault

[@cspnboy14]

I'm going on my second time around with my 2020 JT Rubicon flashing the "Service 4WD system" and the yellow stays for about 3 seconds and then goes away. Mostly when I accelerate from a stop or hit the accelerator hard to pass someone at highway speeds. It goes away but the tone and lightup on the info center is getting annoying. Will this fix it? Been to the dealer once for a faulty speed sensor (thought it was that) but the problem is back. Thanks.

[@zautomotive]

"Service 4WD System" would not be the same issue as the "Service Axle Locker System" that is being shown and fixed by the Z-Locker OEM

[@emmymilam8063]

Do you have to have the tazer too? Or can you buy this as a stand alone item?

My only question is. Can the lockers be turned on while not in 4L? I sure hope it doesn't let it do that. Anyone know????? I know it is my front one because the rear will lock in when the service light decides to go out. I bought 2 just to go ahead and fix or patch the problem. Well, worth $400 for both shipped.

[@jthor8373]

So in other words whether you have the locker sensor problem or not it's better to have this installed as a preventative just in case since it's a common issue.

[@zautomotive]

Installed or in your glove compartment just in case isn’t a bad idea

How often does this happen with the stock setup? Is it a gear change that really helps this problem to occur or is it happening on stock Rubi's just as often? Now I know you are in the business to make money off of these great products but couldn't frequent differential oil changes and cleaning of the magnetic drain plug help to prolong these sensors wether stock or modified if you are saying it's the metal gear debris that's creating this failure?
