Ram 2500 Front Axle Disconnect Actuator 68216944AA

This is a replacement front axle disconnect actuator for 2013-2018 Ram 2500 and 3500 4x4 pickups. It replaces OE 68216944AA, 68216944AB and 40116533. Listed engine fitment is the 6.7L Cummins, 5.7L Hemi and 6.4L Hemi on 4WD models only. The actuator mounts on the front axle housing and is what connects and disconnects the front axle when the transfer case is shifted in and out of 4WD.

When the actuator fails, the transfer case shifts but the front axle never locks in. Common signs are a flashing 4WD light, a 4WD warning message, front wheels that do not pull in 4H or 4L, a grinding or ratcheting noise from the front axle, and 4WD that works only some of the time. Water getting into the motor or connector is a frequent cause on trucks that see snow, salt or mud. Check the connector and wiring for corrosion before condemning the actuator.

Park on level ground with the transfer case in 2H and the engine off. Unplug the electrical connector, remove the mounting bolts and pull the old actuator out of the axle housing, noting how it was clocked. Clean the mounting surface, install the new actuator in the same orientation, tighten the bolts and plug it in. No programming is needed. Test by shifting into 4H and 4L on a loose surface and confirming the front wheels drive, then back to 2H.
