Eaton builds a variety of parts for both OEM and aftermarket companies. We’ve shown our readers a variety of computer animations in the past that demonstrate how various Eaton differential products operate, including their E-locker differential. We’ve never had an actual inside view though, until now.

We recently came across this video, where someone was able to show how the E-locker works with the differential cover removed. Keep in mind that this is with the vehicle supported on jack-stands, and the wheels are spinning at what is obviously idle speed, since there is no fluid in the differential to lubricate things, spinning it fast, or for prolonged periods of time in this type of situation would obviously damage the differential due to the lack of lubrication.

The video demonstrates both locked and unlocked positions of the differential. When the differential locks, you can see the locking pins being moved into position. The film is even slowed down at the appropriate time to make it possible to view the locking pins as the differential rotates inside the housing.

Also noted in the video is the fact that the differential in this particular case is unlocked once the ignition is turned off. A few seconds after you hear the engine shut off, you can see and here the differential unlock.

The Eaton E-locker is available for a variety of applications including Ford trucks, and cars equipped with 8.8-inch differentials. Visit the Eaton Web-site for more information, or to locate an authorized dealer.
