Jeep JL & JT Rubicon Locker Sensor Failure Explained By ROCKRIDGE 4WD. Can it be avoided? 

There is an informative thread on JL wrangler forums how to inject electronic potting compound into those sensors. At 12K miles I potted both sensors on my 2019 JLUR and have peace of mind with new synthetic fluid and potted sensors. The sensors are Hall effect design that has been used in proximity sensors for decades. The sensor are made by TE Connectivity. Oil is not an electrical conductor and the video pointed out fresh oil seeping into them is not a problem, however the oil has tiny metal particulates that over time destroys the sensor electronics. The Z automotive bypass harness is probably a good remedy for many but I personally like to know the locker light is illuminated because it knows it's mechanically engaged with feed-back.

GREAT EXPLANATION. JUST REGEARED MY 21 MOJAVE AND ABOUT 800 MILES LATER THE LIGHT CAME ON. I HAVE ORDERED THE Z AUTOMOTIVE LOCKER HARNESS.

There is thread on JL forum on how to pot the sensors so that the oil doesn't get into the sensors.

So what does it mean if the z-locker doesnt fix it.

So I installed the Z OEM in the front axle. (That's where I have oil leaking in the plug) But now my service axle light stays on instead of randomly going on and off. Does anyone have this issue or thoughts about this? Thinking about a direct wire to a new switch for a solution.

The video is instructive. I'm a guy from Israel and I watched the video you made for the Rubicon differential lock Maybe you have an explanation of how the lock works, what moves the magnet, who pulls and presses. And what electrical signal is received from the position sensor

Excellent explanation, Thank you.

I had my gears changed by Rebel off road , they said it won’t void my warranty but it did

Thanks for this. What's the "z harness" ? I've tried looking that up and don't see anything.

Good info, thanks for sharing!

Why can't you clean the sensor while it's apart? Why would you not?

Whats the trick to getting that bearing off

I bought Z automotive bypass for front and rear and lockers still disengaged after loads, restart the car and it disappeared then problem again after lockers under loads. Please help!

Is this why its referred to as trash lock?

Is this the same on a 2018 rubicon unlimited 4 door

So just buy a new sensor when re-gearing to save a headache

thank you for that!

HEY, I'M EXPERINCING THIS FOR THE SECOND TIME AND HAVING THE WARRANTY WORK FIX THE ISSUE. SOON MY WARRANTY WILL EXPIRE AND I DON'T REALLY WANT TO BUY ANOTHER CAR. HAS YOUR FIX HELD AND STILL WORKING? THANKS

Excellent video. Maybe someone else could hold the camera next time.

Still happens on stock and untouched 2020 JT in first 15K miles

But it also happens to jeeps with stock gears
