Rubicon Locker Sensor

I have a rubicon locker and a rubicon housing that I am piecing together to put under my TJ. However the little black sensor on the pumpkin is beyond saving. I can't seem to find the part number for it either...I can find the ones for JKs just not TJs. Is this sensor even necessary? If I just run a switch for the pump will I be fine? I feel like I will, obviously I won't have a confirmation via the sensor that the locker is engage. Is my best bet to just plug the hole and forget about the sensor?

its a good thing to have the sensor to indicate "locked" or "unlocked"


it can take a little movement to fully lock the lockers.
i always make sure my lights are [ON] before i stand on the gas up a hill.


sorry, i do not have a part number for the sensor. maybe try and find a d44 blown up view schematic somewhere, i have seen them for D60s(when i searched)

Good luck.

The wires to my front locker broke right at the sensor about a year ago, the only place I could find a replacement was at the dealer. I don't have the part number but it was about $90 for the sensor and attached wiring and connector. I've just been running without it, it works fine the light just flashes.

I completely rewired my Rubicon's lockers with a simple on-off switch for both and it works great as is. That sensor isn't needed to tell you when the axles are locked.

All each compressor needs is a simple source of switched 12 volts to work fine. Each compressor has a built-in pressure switch to shut itself off once the correct pressure is reached.

Yeah sounds like trying to track down the sensor isn't worth it. Thanks everyone, I'll just run an on/off switch to the pump like most of you suggested. Thanks everyone!

With a 2000 TJ you don't even have the dashboard indicators to tell you if you're locked or not. Not really an issue. Plug it up and hope they're locked.

I may have missed it, just a warning, don't try and lock Rubi lockers with an ARB compressor or anything else. They only require 5lbs of pressure.

You can use an onboard air compressor or ARB compressor, just make sure a regulator is used!

I don't know that I'd trust a regulator to consistently and reliably reduce the air pressure from the usual 80-120 psi all the way down to the 5 psi required by the Rubicon locker's air bladder. That bladder isn't exactly robust & once it blows out or develops a leak as I have already had in my rear locker, you'd have a very difficult time finding a replacement. I got very lucky on finding a used bladder replacement for my rear locker, they are as rare and hard to find as hen's teeth.

I certainly would not go that route, one bad air pressure regulator could prove very expensive if not fatal for the Rubicon's locker. For the Rubicon's locker, I'd go to a lot of effort to only use an OE air compressor to give that locker every chance of remaining operative and reliable.

Makes sense... That would be a major bummer.

McChillen, if you are still looking for the axle lock sensor P/N it is 52104610AA for an 04/05 TJ Rubicon front/rear axle from chrysler

Even with the sensor, which is a little plunger that senses the position of the actuator, your 2000 TJ has nowhere to plug it into. I may be wrong because I haven't looked at my FSM but I'm guessing sensor signal goes to the PCM and then from the PCM to the dashboard indicators. Neither of which your 2000 TJ is equipped for.
Plug the sensor hole and hope they're locked.

It doesn't seem that the signal goes to the PCM...
This write up:http://www.links4jeeps.com/forum/ind...?topic=11630.0 shows the wiring into a non-rubicon and he didn't touch the PCM and still had a signal light to show the locker was engaged. But I still think I'll just plug the hole, just doesn't seem worth it to pay $80 for a sensor.

I see what you're looking at in that install write up. That's new info. An added aftermarket dash indicator.

I was saying you wouldn't have the OEM dashboard indicators. Which, more than likely but as I said I haven't looked at the schematics, the sensor signal goes to the PCM then to the dash assy indicator on the factory Rubi dash.
