That would be the 4WD actuator.I have a small gear oil leak coming from what I believe is the front diff (I'm not super familiar with IFS), it appears to be coming out of a sensor or something on the side of the diff and I'm having trouble identifying exactly what this is. Any ideas? Is it hard to replace and how long can I let this go before fixing it? I'm currently out on a road trip and would like to get back to my mechanic in Denver if possible. Thanks!

Unclip the wires to the actuator and unscrew the actuator.
