The locker sensor in Wrangler JL and Gladiator Rubicons have started to become problematic. When they fail, it usually starts out as a blinking locker indicator on the dash, which then ends up in a “service axle locker” message. Once the locker system is in this fault state, the lockers will no longer engage.
The repair would normally be to replace the sensor, but the part is not available separately. The next best thing would be to replace the locker assembly, but that’s not available either. The current solution is to replace the entire axle assembly, but due to the commonality of this problem, they are on national back-order.
The Z-Locker-OEM from Z-Automotive solves this problem. Bypassing the problematic sensor, it allows the locker to operate without the position sensor yet provides the proper feedback to the Jeep’s computers to keep the system operational without any errors or warnings. You get fully functioning lockers with no side effects from using the Z-Locker-OEM.
Installation is simple; unplug the locker, plug the Z-Locker-OEM in between the axle and Jeep harness. This can be done in seconds with no tools. Will not harm the Jeep’s computers - it uses the same signaling that it expects from the sensor. Connectors are the same ones used by Jeep and are watertight.

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.

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.

@@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

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.

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.

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

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 Жыл бұрын

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

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.

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.

@@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.

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?
