Just saying thanks
Hey guys, just picked up a 1999 Expedition AWD having the binding problem. I've been scouring the internet for the fix and was getting pretty worried. Just wanted to say, I pulled the 104 fuse, and it worked like a charm. Thanks guys! Now I've got a little time to get the bugs worked out.

Hey Everyone, This post just helped me out big time, Thanks for all of the info Alloro. I just purchased a 99awd Navigator w/113,000 miles on it and this was the problem that it had when i purchased it. I joined ford-trucks.com lastnight and this morning pulled the #104 fuse and the truck is driving and turns like it is NOT locked in 4wd. I will be replacing the speed sensors within the next week.
Thanks, Chuck

About 1.5yrs ago I had an emmediate drop in MPG in my Navi. Dropped about 3mpg, and I have been trying to solve it ever since. Now I am here! I have an 01 Navi with A4WD, 4H, 4L. All instrument lights show as if it is working correctly in and out of A4WD & 4H, and I can here it engage when going in and out of 4L. But I do not think it is ever actually coming out of 4H. In A4WD, the front wheels slip/skip when doing a slow tight turn on slightly wet asphalt, or on any dirt/gravel. I've had my front driver side axle (by the tire) make a loud popping noise when turning tight on dirt getting onto the throttle twice over 2 years (so loud that I got out expecting to see something laying on the ground under it). The sunroof leaks when there is a downpoor and it runs down the posts, which has always scared me about electrical issues. And when I've had it in the shop off the ground, all 4 wheels were turning at the same speed while in A4WD. My rear axle started shuttering last spring, and we put in an auburn locker rear end (limited Slip), we did not change the ratio. But the problem was present before that was done. I also think I am in need of new driver side balljoints, as I can hear a clicking from that corner when making slow speed manuevers. I bought the ride with aftermarket wheels on it. 20" rims, I put on new Toyo A/T tires and had them get me sized as close to stock hieght as possible, but still eneded up almost .25" off. Is it possible for it to be stuck in 4H? How do I check it? How do I fix it? Hope that is enough information to get somewhere with this..

Shortly after I posted on here my ABS dash light started coming on also. I took it to the dealer later in April to get the code read, and they told me to replace my speed sensors. After replacing all of the speed sensors I still had the ABS light on, and rather than paying the dealer more money to chase the problem, I decided to go to my regular mechanic (the old timer that we all know through someone) in May. He reads the code, speed sensor code again, then he walks to all 4 wheels and pulls and prys on them with a breaker bar. He follows that up with asking me if I'm hearing any noise from that front right side that I mentioned in my original post, "Yeah I have actually" I told him. To the point, the front driver side CV joint and bearing were going out, which was causing the ABS light to come on and the speed sensor to misread, which was also causing my ride to go in and out of 4WD. I had both sides on the front replaced (Whole assembly: bearings, sensors, cv joints), and I am now rolling smooth again in all situations. I got back a little over 1mpg with that, but I followed that up with new coils and plugs which got me back another 2.5,pg, so I'm back to a bearable 15.8hwympg avg.

In that case the shift motor and the front clutch are okay. The most likely culprit is the speed sensor on the front of the t-case. The lack of a signal from the front sensor gives the A4WD module the impression that the front axle is stationary while the rear one is not.

but mine is a 2002? After more research I think it is on the front transfer case near the top? does that sound right?

I'm running into the same issue with my hall effect sensors and I just figured it all out. If i were you I'd skip all the complicated diagnostics and STOP throwing parts at it hoping it fixes the issue.
What you SHOULD do is get a bluetooth code reader on amazon and pair it with your phone. Download FORScan in the app store and have it scan your Ford. FORScan is designed specifically for Ford vehicles and it will talk to ALL of the computer modules in your car and identify the problem, not just your ECU. When i did this it immediately told me what was wrong based on the DTCs stored in the PCM. If there's a problem with either of your hall sensors, then your cars computer already knows about it and will tell you. This method will not work with Torque or other OBD2 programs. Don't blow money on parts you might not actually need, scan your cars computer modules properly and it will tell you what's wrong.
