unplug the plug at the actuator on front diff blow out both ends and look at the connections make sure the are clean and then apply dielectric grease to both ends and then try it if that dont work make sure you have power at the plug when switch is pushed also check switch on dash for same things. Good luck

 

Good advice by hoghntr204. Probably is the actuator.

 

I have power at the switch and power at the plug where the actuator plugs into

 

Was going on here to ask the same thing. Same problem here. Leaning towards actuator. So being said, I need one by wensday this week, any chance?

 

Well I disassembled the actuator. Seems as if it's only pulling it out of 4wd once I reset it to do so. But it won't do anything once I disengage it and try to reengage it again. So guess it's time to buy a new actuator

 

Should be covered by warranty.

 

Been several go out recently (mine included-and yes warranty covered it):

Well purchased a new actuator. $219. Now everything works as it should

 

Where did you purchase? Which site I probably need one
Thanks

 

That was my first failure around 400miles. Thank you warranty.

 

My 3 year old 2012 Cat has a "delay" in engagement and also in disengagement. Sometimes I'll hit the 4wd and then a few seconds later bouncing thru the rocks "Bang" it engages.

Other times trying to disengage lock (so I can steer) it takes a bit of forward and back to get it to let go.

After seeing the little plastic gears inside the actuator and studying how the actuators work it is a neat design but seems like the little motor(s) in the actuator could stand to be more robust to overcome the friction of the crud that gets into the seals.

My demented little pea brain has been formulating a "manual lever system" to control the little push rods (and do away with the electric plastic actuator box all together).

 

I have not dis-assembled the old one yet. I was thinking about doing levers and cable lock up myself..

You got pics?
