Manual hubs are pretty much a thing of the past with dash selected drive systems. the first thing you need to do is verify the operating method of your transfer case, and look there for problems. Inside the cab is usually a protected environment, where as the connections on the transfer case itself are not. If it is electrically operated disconnect the electrical connections and soak them with a good electrical connection cleaner available from your automotive supply store, then use a brass brush to clean the connectors (make sure the battery is disconnected by removing the negative terminal) and then put everything back together, and check the operation. Since you state it is erratic operation, I doubt it is a vacuum operation issue as vacuum operated controls rarely fail intermittently, However to check this it is easiest to simply route a temporary vac line to a vacuum source and the control on the transfer case and see if it operates the transfer case. if it does, then follow the original vacuum lines (from the source and to the transfer case) back to the dash mounted control looking for damage, and replace as needed, if no damage is found look to the control itself. It MIGHT be worth your while to save time on trouble shooting a vacuum leak by just replacing the vacuum lines right out, but you need to base this on your budget vs your time. Chasing vacuum leaks can be a problem in itself and is often just easier to start out by replacing the line if it is suspect.

    No problem Jim... I've been off roading for almost 40 years, and have had experience with almost every 4wd driveline out there and in some of the worst conditions to repair them to get them home (even to the point of using a nickle and jumper cables to braze parts together). If I dont share what Ive learned its useless...

The other answers are feasible. If a vacuum problem you can try using a vacuum pump to see if the vacuum lines are intact. The electric system is usually less dependable. Sometimes the electric switch on the dash is at fault as they use 1 wire to move the shift solenoid for all positions and only vary voltage to get the shift solenoid to travel into different positions. Even a broken LED indicator light on the dash 4x4 shift selector can throw off the voltage. This gives you different functions for the correct twist of the selector. Can't remember the electric values for each position but info is available online including pin position.

There are several things that can cause this. Without further info, I.e. Manual locking hubs or automatic hubs. I am going to assume it is an automatic hub system.
1 pv solenoid could be sticking.
2 vacuum leak in the pv hubs (actuator(s))
3 vacuum leak in the plastic vacuum tubing to pv hubs and sol.
there is also a shift motor that could be faulty or the wiring or connectors to them.

I would start with a visual inspection of the vac hoses, and make sure there is not a loose hose or kinks, or crack.
also check all the connections at shift motor for water ingress or corrosion/poor connections.
I would need more info for this veh.

Ford explorer 2000 all wheel drive not working


all wheel drive vehicles have to work at both ends all the time unless you have a major failure in the drive train. That is why it is called all wheel drive as opposed to 4 wheel drive. With 4 wheel drive you have the option of rear wheel drive or 4 wheel drive and normally in a high ratio or low ratio gear selection. With some all wheel drive vehicles there is a selector that locks the middle diff and creates a 4 wheel drive option without the high/low gear ratio option. So in practice if the both front wheels are in the bog then there is no all wheel drive as the centre diff is working as it should and placing all the action in the rear wheels which will not be turning as they have traction so the front wheels spin faster.. If you have a centre diff lock option ensure that it is operational.

Something you can do is to tap the 4/4 motor under drivers side on the back of transfer case with key on engine off. Have someone work the buttons as you gently tap the motor. Don't hit so hard as to dent it. Usually works.

Go to the engine compartment where the relays are located with the fuses. Check or replace the 4 wheel auto engage relay , maybe is not working. Is very clearly mark, I believe is the top right one looking at the bost front front of vehicle to the back. There is a diagram drawing of each relay in the cover, so you can't go wrong.
