Hi,
I've had elocker in a 2014 3.55 and a 2019 3.31, never experienced a low speed unlocking. I usually unlock it with the dash switch after I gain traction at low speed, supposed to unlock at 10-15 mph which I never encounter the way I use it.
thanks,
Jerry

Perhaps they just unlock when there is no load on them. 2 wheels spinning on the same axle can cause a vehicle to swing out in the back end. It would be a clever design feature to have the wheels auto-unlock when there is no load so that the rear would correct itself and stop spinning into the car in the next lane when the driver let off the gas.

I tested my elocker on a gravel/dirt road and it functioned as advertised. I did not get to 20 mph though.
The manual states the following:
1. You can lock/unlock on the fly
2. It will unlock above rated speed and re-lock automatically when back at or below rated speed
3. It will unlock if anti-locking braking is activated

Per the manual:
The following conditions will affect the electronic locking differential:
The following conditions will affect the electronic locking differential:
- The electronic locking differential will not engage if your vehicle speed is above 20 mph (32 km/h) in 4x2, 4x4 Auto, or 4x4 High modes.
- The electronic locking differential will not engage if your vehicle speed is above or 56 mph (90 km/h) in 4X4 Low.
- The electronic locking differential may not engage if you press your accelerator pedal during an engagement attempt. A message may display in the instrument display guiding you to release the accelerator pedal.
- In 4x2, 4x4 Auto, and 4x4 High modes, the electronic locking differential will automatically disengage at speeds above 25 mph (41 km/h) and will automatically re-engage at speeds below 20 mph (32 km/h).
- In 4L (4X4 low), the electronic locking differential will automatically disengage at speeds above 62 mph (100 km/h) and will automatically reengage at speeds below 56 mph (90 km/h).
- The AdvanceTrac system has the ability to take over control of the electronic locking differential and disable it during driving maneuvers when necessary.

The manual is a little confusing. mine says in 4 x 2 it will not engage above 20mph; will reengage below 56mph; and will not engage while throttle is applied. One of these thresholds may have played into your scenario. It is hard to tell what is going on while driving. I suspect that when your rear wheels break lose they accelerate to a higher speed than you think. With these thoughts in mind, are you coming to a complete stop with no throttle before engagement?
Since the lockers are designed to engage and disengage when the vehicle is in motion I doubt that your experience constitutes abuse on the clutches if not constantly repeated.

Ford E-Lock can disengage when the axles de-accelerate. The action is described about 16 minutes into the video. It's on a Eaton E-Locker but very similar to Ford OEM. KM

This explains how it works to a degree.

There aren't clutch packs as such like a TruLock but the engagement device is still a replaceable maintenance item. Below is the rebuild kit for the 8.8" diff.
