I hope everyone has their answer by now about this actuator leaking. If someone is replacing the actuator, it is to make money. The leak is caused by a 30 cent o-ring. The reason it costs so much to fix is that the transfer case has to taken down, broken apart, and a few little bolts and circlips removed, attention paid to where the shift forks are. Then, the actuator can be slid out, that sealing area meticulously cleaned, new 30 cent o-ring, and I also used RTV lightly coated on the adjoining surfaces. Then, meticulously clean the sealing surfaces of the case, and reseal it with good RTV. A nice continuous bead, but not too much. I use enamel reducer to do the very final clean of my surfaces and that seems to work well for me before applying RTV. Be anal about drawing the surfaces together and using a torque wrench. Finally, (ask me how I know....) do not over grease your driveshaft yokes. It will apply too much thrust load on bearings that were not made for so much thrust. It is just a whole lot of busy work, but from what I see, and what I've read, anyone who goes down the path of getting a whole new actuator is being taken for a very expensive ride. This job is not technical, but you just have to go into it trusting your sound mechanical ability. And have your truck high enough. You can never have it too high, but it makes it a lot more challenging if you are just on plastic ramps like I was.
