Front axle actuator on my 1984 Chevrolet 4x4 not engaging front axle

SOURCE: 4x4 not working when i shift it in 4x4 auto trans

Find the accuator on the front axle it has a two wire pigtail and threads into the axle housing. Check for power and ground if you have both when the transfer case is in 4x4 the replace the accuator. They are available at most parts stores and are a very common problem. Let me know how it goes.

hi guys i would check all the small vacume pipes that conect the sol valves toi the vacume actuators having just replaced the engen in mine i found that these do not have any clips holiding them on tight and can get oil on them and become oversized and leak you can test the diaframes in the actuators by putting a length of pipe on one port and sucking by mouth you can hear the actuator move and then find you can put toung on end of pipe and it will hold a vacume if it does not then chances are the actuator diafram id u/s hope this helps bill

Even though you checked the vacuum lines and found no leaks it does not mean there isn't a problem. The check valve in the line closest to the firewall actuator is probably your problem. Had the same issue replaced this line and solved it. The check valves in the vacuum lines are your best next guess.

Pull the actuator out plug it in and have some pull it in 4 wheel with the key on and see if it moves. If not then the problem is between the there and the 4x4 switch by the shifter. Check to see if there is power to the wires and then follow them out. Maybe one is broke or even a blowed fuse.

Sounds like the chain in the transfer case has broke or the linkage is out of adjustment
