I just wanted to know if it is a common problem with older explorers for the push button type 4x4 not to work properly I have always had regular hubs [3old broncos and to old pickups]. no light or anything comes on when you press the 4x4 button high or low range.I dont want to bang my head against the wall all weekend I hope thats a better description of my problem. I am new to this computer thing. thanks in advance.

Yes it is a common problem. From your limited description, I'm a little uncertain if the problem is at the transfer case or the hubs. The shift motor on the transfer case frequently has trouble shifting. There are instructions on the net for how to remove the shift motor and open it up to clean and "rebuild" it. The auto hubs frequently don't engage. Both issues have been discussed frequently here and across the internet.

thanks for responding. I am going to check the shift motor 1st, I had somebody press the button while I was looking it didnt do anything or make any noises like it was trying to engage.Somebody on a previous thread said there was a reset on the module. But Im not sure where that is. It seems to me it could be a reset becouse nothing happens when the button is pressed.This is pretty fun reading and talking about trucks. I am also working on a 68 4x4 quadcab
thanks
thanks

I had lots of problems with the front hubs when I had a '92, plus a bad shift motor at about 200,000 miles. The front hubs have some fragile parts that don't seem to like extreme cold, but once I got a decent mechanic to rebuild them right, I was good for about a decade of driving.

Yep... very common problem. I don't know about diagnosing the hubs because I swapped mine out for a set of Warns as soon as I bought it.
One thing that sometimes "fixes" it if the motor is sticking (temporarily, enough to get you out of a jam sometimes) is to crawl under there and whack the shift motor with a hammer or something. Obviously not enough to break something, but that sometimes helps if the motors sticking and you need to get home.
I've found that I've had MUCH better success with the 4x4 button this winter since all last spring/summer/fall I made a consious effort to engage the 4x4 every couple weeks.
Some good info here...

Good luck.

Check for 12VDC on the single brown wire the enters the T/C when the switch is in the 4H position.

"The electric shift motor, mounted externally at the rear of the transfer case, drives a rotary helical cam which moves the 2W-4W shift fork and 4H-4L reduction shift fork to the selected vehicle drive position. An integral position sensor provides information to the electronic module on current motor position"
And regarding the magnetic clutch...
"... The clutch is used to spin up the front drive system from zero to vehicle speed in milliseconds. This spin-up allows the shift between 2-high and 4-high to be made at any vehicle speed...."
So I think the motor still comes into play for all shifts (at least on the gen 1's) and the electromagnetic clutch helps with the shift on the fly part of it..

funny, I hear so many complaints about the push button 4X4 set-up on suvs and trucks, but my '96 F150 I just sold, it had push button 4X4, and the truck has 165,000 miles on it, I put 9K on it, and I never had a single problem with the 4X4.
