Just how hard is this to replace? I have been dealing with the slow engagement blues for a couple years, but it always eventually hooked up. I used a few times this summer for pulling trees down (okay guiding trees down, not actually yanking them out of the dirt) and had no problems.
Now, I get not lights, no front end engagement and white knuckles on the way to work. What do I need to check to make sure the actuator is bad? The 4WD fuse is good. How hard is this to replace? I know GM came out with an electro-mechanical actuator as and upgrade, are there any other options? Manual hub conversion?
