Factory E-locker in 2005
Hey gents,
I saw lots of discussion about Eaton lockers, trutracks (which I like), ARB for the front etc etc when I searched - but didn't see this:
I have a 2005 F-350 6.0 Power-stroke. My understanding is its the same axle as the newer super duties that have factory e-lockers.
Any reason we can't just swap in a factory e-locker unit (used or new) and be done with it?
I dislike air-lockers. They always leak, or the compressor is froze up, etc etc etc.
Thanks

That would be hard to do. You'd need a new differential housing that would accommodate the hardware, or swap the axle. Then you'd need to find a way to control it:
This is from the service manual for 2013.
When the operator sets the Mode Select Switch (MSS) to either 4L, 4H or ON position (depending upon vehicle option content) to activate the ELD , the ELD icon displays in the Instrument Panel Cluster (IPC) message center. If the vehicle is driven above the disengage speed, the IPC message center no longer displays the ELD icon, alerting the operator that the ELD is disengaged. Once the vehicle drops below the re-engage speed, the IPC message center displays the ELD icon again. If there is a malfunction with the ELD system, a "CHECK LOCKING DIFFERENTIAL" message is displayed in the IPC message center, letting the operator know the ELD is not engaged.
The differential locks when a Pulse Width Modulated (PWM) controlled magnetic field coil located inside the differential energizes. A collar within the differential moves toward a differential side gear and engages a dog clutch within the differential. This locks the differential side gears and creates the locked differential.
The Transfer Case Control Module (TCCM) activates the ELD . When the ELD is engaged, the TCCM sends PWM voltage to the ELD field coil located in the differential. This voltage is initially 98% duty cycle, and then tapers off to 40% duty cycle after 30 seconds. In order for the TCCM to activate the ELD , certain conditions must be met.
TCCM Input Conditions
MSS set to ELD position
Average rear wheel speed versus average front wheel speed must be less than 15 km/h (9 mph) (via High Speed Controller Area Network (HS-CAN) communication from ABS module)
Operating range (voltage between 9-16 volts)
DTC setting range (voltage between 10-15 volts)
Ignition in the ON position
Throttle Position (TP) less than 50%

Interesting, Leave it to ford to be complicated.
In the old Nissan Frontier/Xterra world - we'd simply swap in the locker and wire it to a 12v switch to apply power to keep it locked (solinoid). In the end that was all the BCM did. Very easy retrofit.
EDIT: Obviously I wouldn't plan on the truck knowing, or in any way controlling the unit - it would merely come down to the PWM control of the coil on demand (aka when I flip a switch)

The E-Locker used in all newer Ford is simply a two wire solenoid. All of the fancy operation quoted from the Ford Service manual earlier in this thread is simply stating the strategy the BCM uses to control the ELD. I was a Ford Service engineer for 5 years and I am planning on doing a whole axle swap on my 97 F250 so I can have rear disc brakes and the ELD only problem is I can't get 4.10's. All that is needed is a toggle switch. The axle should be a direct bolt on for all 99+ Superdutys with rear disc brakes.
