Eaton ELocker Service Kit For Various Dana 60 Vehicles
A Dana 60 with an Eaton ELocker is supposed to lock both shafts the moment you hit the switch. When the light comes on and the truck still spins one tire, and the wiring checks good, the electromagnet in the axle has usually quit. Eaton part 26665-00S is the stator and armature service kit for its Dana 60 ELocker. It is for owners of Ford Super Duty, Ram HD, GM HD and built Jeep or rock-crawler Dana 60 axles who want to bring a locker back to life without buying a new one.
In a Dana 60 ELocker, the stator is a 12-volt coil that sits on the carrier, beside the locking mechanism. Switched on, it pulls the armature plate in. The drag on the armature turns the ball-ramp locking mechanism, which forces the lock into the side gear and ties both 30 or 35 spline axle shafts together. Switched off, springs back it out and the unit runs like an open diff. On a heavy truck that tows, plows or wheels on big tires, the coil sees heat and the lead sees flex, so the stator is the electrical part that wears out. Eaton's application guide lists 26665-00S as the Stator/Armature Kit for the Dana 60 ELocker. One guide edition lists the stator assembly, armature and retaining bracket; another lists stator, bearing race, thrust bearing and retaining ring, so compare the box contents to your teardown.
Rule out the cheap stuff first. Make sure you engage at a stop or a crawl and roll a few inches so the armature can drag in. Then check for 12 volts at the axle connector with a helper working the switch; Eaton runs the locker through a relay because the dash switch cannot carry its current. The step-by-step order is in our ELocker not engaging guide. If you have voltage at the axle and the locker still stays open, pull the cover and inspect the coil and armature. If instead the locker clunks, binds or grinds when unlocked, the gears are the problem, not the coil; that is the 26882-00S Dana 60 35-spline gear service kit.
Eaton matches 26665-00S to the ELocker in its "Various Dana 60" column, which covers the Dana 60 ELocker in both 30 and 35 spline versions. It does not fit Dana 30, Dana 35 or Dana 44 ELockers (Eaton uses 26663-00S for Dana 30/35 and 26664-00S for the Dana 44 2-pinion unit), and it is not for factory GM, Ford or Ram lockers. Eaton's newer ELocker4 Dana 60 units, like the 14022-010 for 4.10 and down and the 14023-010 for 4.56 and up, are later designs; read the part number stamped on your case and match it before you order, or send us the case number with your year and VIN.

It is the electrical side. Eaton lists it as the Stator/Armature Kit for the Dana 60 ELocker. If your gears are worn, the gear service kits are 26881-00S for 30 spline and 26882-00S for 35 spline.
Eaton lists one stator kit for its Dana 60 ELocker, covering the 30 and 35 spline versions. Only the gear kits are spline specific.
Do not assume so. The ELocker4 units like 14022-010 and 14023-010 are a later design. Read the number on your case and send it to us with your year and VIN so we can confirm.
With the switch on, check for 12 volts at the axle connector. No voltage means the problem is the switch, relay, fuse or wiring. Voltage present but no lock points to the stator or armature.
If you reuse the carrier bearings and return each shim to its original side, the setup should come back the same. Check backlash with a dial indicator before you seal the cover.
Use the 75W-90 or 75W-140 gear oil your axle calls for. Friction modifier is not needed for the ELocker.
