You may have noticed in my post Rubicon trip report that my rear locker again failed me, ugh! After again confirming my electrical was okay, I realized this needed more expertise to solve.
Last week I took the LJ to a local 4x4 shop that does axle work. They tested it out and the locker was working for them in all of their test scenarios. What to do now? I know it did not work in key situations now on 3 group trips to Moab, Sand Hollow and the Rubicon. I asked them to pull it for a physical examination. There is no visible evidence of a problem and the electromagnet is working as it should. The shop calls Currie to discuss further. Here is the major curveball that came out of the shop's call - the rear locker is not an Eaton unit, it is an Auburn unit!!!
Apparently when I ordered my axles in October 2022, Currie could not get an Eaton Dana 60 locker and installed an Auburn locker instead. I recall from 2022 that Currie could not get one of the lockers I wanted but I remember that being the front locker. Further, when the axles showed up in the crates I am pretty sure that there was an Eaton harness and documents in the crate with the rear axle. Likely I remember it wrong and now that I look at my Currie shipping docs they say front TJ axle with Eaton e-locker and rear axle with "e locker".
On Friday the shop calls Auburn and another major revelation is that Auburn admits they had some quality problems with Dana 60 lockers built in 2021, the time mine was manufactured based on the serial number. You would think they would agree to warranty my locker on the spot. But no, they want the shop to send it to them for further investigation.
I had been mentally preparing to go with an ARB locker if we had no smoking gun after the shop investigation. But for me this is validation that my rear locker was defective and must be replaced. Now I had to decide what to do and I've decided to go back to my original choice - an Eaton e locker. I have been channeling a lot of negative energy to Eaton since my first locker issues in Moab in 2025, but now I realize all of that was misdirected as my front Eaton locker was rock solid and the rear was not even an Eaton.
This week I call Currie and tell them my whole story of rear locker issues and they did me a very solid thing – they are sending me an Eaton e locker FOC. I just have to send back the Auburn locker. I feel this is a very fair solution and in a few days I should be back together and have my rear locker issues finally solved.
