4 wheel drive not working

I have a push button on my dash for the 4 wheel drive. It doesnt work. I replaced the original hubs with manual hubs and seems it works as far as the hubs. My problem is, I dont know if the transfer case is always feeding the front drive train to the wheel axle. It seems to me, that there is something that the transfer case has to engage to make the front drive move, thus moving the front axle. Or, does the front drive train always spin?
I thought putting on manual hubs would fix it, but I still think that maybe the front drive is not engaging. Which means, I will still have to replace or troubleshoot the electronic module in the back of the super cab, to engage the transfer case to make the front drive spin, thus making the front axle spin.

I know about the manual hubs and the button. Dangit tho, yesterday when I tested it on loose soil I forgot to push the darn button in tho.I was very distracted with alot of things. Anyway, the light next to the 4x4 button comes on and the 4x4 light underneath the speedometer comes on. Which is a good sign but I still have to make sure the connection to the transfer case is good and that the transfer case is working. Any tips? The front wheels were not spinning before I put the manual hubs on. That is why I put them on, in hopes it would fix it. I guess the next thing to do is test it again, and make sure I push the darn button in this time. Then check voltage to the transfer case with the button on. If I get voltage I suppose it could be the transfer case, but cross our fingers that it is not. Any other suggestions would be appreciated. Oh, I do have another question. Does the front drive train and the front axle have some type of connection point that I should be concerned with? For instance, maybe the front drive train spins but the axel does not spin?

This will be my last question, I can take it from here. I did not understand your comment about "one tire spinning". 1. The front drive train will kick in once the motor to the transfer case kicks in to the transfer case. 2. The front drive will turn, thus, turning the front axel. The axel will turn but unless I am locked in on the hubs, the tires will not turn. 3. So, if the transfer case engages with the front drive train, the front drive train will turn the front axle. If the hubs are locked, then the tires will spin.
My question is, I dont understand what you mean about "one tire spinning". If both hubs are locked in, wont the front axle turn both tires?

Its all working. What happened tho was when I was done testing it, I went to turn off the button on dashboard, (after putting hubs on free), and the 4x4 lights on the dash would not go out. They finally did, but that was weird. Thanks for your help.

Don't work, what could be the problem

The 4X4 doesn't work at all, it will not switch from 2X4 to 4X4, the year is 2000

I hear absolutely nothing, not even a click

I have a 1996 Ford Ranger 4X4 w/4.0 liter engine, A/T, w/ 103000 miles. The autohubs have been replaced by lockout hubs. The 4 wheel drive will not lockin. I was told to disconnect battery and wait then hook back up. This worked once then again quit. The 4 wheel drive will not engage.

I just bought a 92 ranger,,,v-6 with a 4.0L manual transmission,,,it has push button 4x4 with lock out hubs,,,i failed to check it before the purchase,,,when i went to put it into 4x4 today it went into 4x4 high but would not engage into 4x4 low,,the light for the 4x4 high comes on but not the low,,,is this a transfer case problem or could it be something electrical,,,i dont want to spend anymore money on this that i have to,,,

It is very possible that the automatic locking hubs are broke that engage in the axle behind the tires up front. My 1994 was in a wreck, and I had the mechanic check everything out, and he said the front transfer case drive axle was turning for the four wheel drive to work, but that these piece of junk auto lockers Ford put in were worn out. I have heard of people replacing them with standard locking hubs and they work just fine. Hope this helps.

1991 Ford Ranger 6 cyl Four Wheel Drive Automatic

I have a 1991 ford ranger with a 4.0 v6 I had a new tranny put in and now my 4 wheel drive doesn't work. Ther is a clicking sound coming from the jumper seat behind the drivers seat. I would imagine that is the brain for the w wheel drive. I think they forgot to hook something up if anyone could help I would greatly appreciate it
