How to change a Chevy blazer 4 wheel drive actuator?

Answer 1

On the front differental there will be a tube looking thing about 6 inches or so long sticking out of it. At the end there will be be a spot to stick a wrench on, that's the actuator, just take a crescent wrench and unscrew it out and unplug the wire. And screw the new one in place and plug it in. Wa-la that's it
