Ford Excursion :: Stuck In 4x4 With Hubs Locked
Dec 13, 2015
A relative's '04 EX Limited is having an odd problem. He put it in "4x4 Low" to back a trailer into a barn and after the task was complete the transfer case wouldn't shift out of low range. He tried multiple times and after about 5 minutes of fiddling around with it, it shifted into 4-Hi but wouldn't go back to 2-Hi. The hubs are in the "auto" position and will not manually unlock (the selector turns). 4x4 indicator on dash is not lit. Could the dash switch be bad? Why would the transfer case and hubs act up at the same time?

Is it ok to keep my front hubs locked in and the switch in the 2wd position for everyday driving? Only reason I do it is because in auto it doesn't always go into 4wd.

On my new to me '03 Excursion (I've owned it for 1.5 weeks now), I'm starting to get through the 1st level of issues (Wandering - fixed, Speedo/ABS issue - still working on that, changing the rear diff fluid this week, hopefully).
Now, I want to look into why the manually locking hubs won't turn. When I brought it up to the Previous Owner, who was about as mechanically inclined as my Golden Retreiver, he said "these are auto locking hubs. I never turned those things before".
They are frozen in the non-locked position, so I have to pray that I never need to actually manually lock them.
Any lucky experience at un-freezing stuck hubs? I've started the liberal application of PB Blaster process.

The drivers side Hub seems to be stuck in Locked Position. I lifted the Wheel and when I turn it the Front Drive shaft turns and you can feel a fair amount of resistance.
I lifted the Passenger side and it spins free. I then started it and put it in 4WD and the passenger side engaged and i could not free spin the wheel. I then lifted the drivers side again and it would not spin. Turned off 4WD and it spun again but moved the shaft.

I have been recently told that it is bad to drive my F350 with the manual hubs locked when I do not have it in 4 wheel drive mode. There are times when plowing snow that the roads are cleared but I am still plowing driveways. I do not want to travel with 4 wheel engaged in the scenario. So I would just disengage 4 wheel and travel to next stop. Is this a bad procedure?

Warn Premiums, installed them and now the 4x4 is engaging, but still have a grinding issue. When the hubs are locked and the switch is in 2 wheel drive, the frond end is grinding, if I switch it to 4 hi, the grinding goes away.

Its a 2016 F-250, 6.2L gas truck with the electronic shift on the fly transfer case.
I have put right at 22,000 miles on it like this, frequently at 70-80 mph.
What are the odds I have damaged it and is there anything I should do now that I discovered it - other than put them both in "AUTO".
Truck has been to the dealer twice and not once was this noticed. They blamed the squealing on the brakes which I knew it wasn't.

I have an 04 F150 (4.6, auto, 4x4, SCrew) with 300,000 miles. Any success modifying existing 4X4 IWE actuators so they are always locked in?
My last set of actuators didn't last long My vacuum is too low under hard acceleration... Actuators partially engage leading to early failure.
I'd like to take an actuator apart, modify it so it's always locked in. Some loss of mileage? Other ramifications?

Well long story short, I had the the factory hubs in my 04 f-350 and I was driving down the road and it started making this horrible popping noise. So I pulled over and couldn't find anything and just curiosity locked in the hubs and all was fine. Made me think my hubs were bad, so I went and bought the warren premium hubs, installed them. Went for a drive and still the same noise is there when they are in free spin. But once they are locked in its fine. What this could be? Wheel bearings?

But on my 2000 SD V10 the hubs are worn I just cant find which way to turn them to auto ?
I'm getting popping and such so I think I'm locked while turning.
Also.... IS there a way to check the COPS with a multimeter? I think I got a bad one.

Had to make a sharp circular turn last night in a parking lot, with the steering turned to full-lock...noticed a very audible clunking or clicking noise during the turn...went away after full-lock turning was released. My hubs are locked in...but I was told there was no issue with leaving them locked in, even during the summer. And there shouldn't be...4x4 disengaged, of course. Must have been the u-joints clicking / clunking? Problem?

Just got done with a ball joint replacement on my 2003 F550, everything went together great, just as it should. Until I got to the drivers side hub lock.
I have Mile Marker 449s/s manual hubs. Turn from free to lock and theres this loud clicking sound about halfway to LOCK (passenger side doesn't do this). Hub will stay locked for about 2 rotations, then it unlocks and makes a clicking sound. You cannot turn the hub back to FREE, it gets halfway and stops. I tried forcing it and broke the spring fingers inside. Have a new set on order.
Is this a locking hub issue or an assembly error? I was going to take these steps.
- Take passenger side hub lock off and see if it operates normally or same on drivers side.
- If same, remove axle and re-seat/re-assemble everything again
Anything to specifically check? All the parts went back in, washers were in correct order, outer snap ring is in groove.

Ok so some one locked my hubs and put the truck in 4x4 4low i assume my aunt was driving it, truck wouldn't shift from 2 to 3rd is this normal since its in 4low. The shifter also seems pretty stiff and 4wheel isn't used much if there a way to know if 3rd gear toon a crap? Trans fluid seems fine not dirty or burnt...

2008 F350 hubs wont stay locked in when in auto position. everything stays locked while in manual and 4x4 works fine, but in auto the hubs wont stay locked while spinning. I was trying to find the problem when i noticed that one hub stays locked all the time and the other locks and unlocks as it should but it wont stay locked while spinning. My question is do I have two bad hubs or is their a leak that wont let the hub stay locked? Also on the hub that wont unlock is this a leak problem as well or a internal problem?

I get a very bad vibration when my hubs are locked in. If i unlock the hubs it goes right away. It don't matter if the transfer case is engaged or not.

I have a 2007 Tacoma 4x4 and until recently everything was fine. I even got almost 75000 miles out of the stock tires. About a month after the new tires the battery died so I replaced it. Since then the front seems to have a slight vibration and a slight noise. Kinda sounds like when you hear a 4x4 with big mudder tires on pavement. Both the vibration and sound are so slight that others cannot hear or feel it, I just notice having driven it for over 5 years, mostly highway.
When rotating my tires I noticed the front "axles" (don't know the proper name) turn with the tires. With the wheel off I tried holding the "axle" while turning the disk brake but it was as if the hub was locked in. A neighbor who seemed to think he'd heard of it before asked if I'd changed out the batter or had to disconnect it which of course I had. He said that maybe the electronic hubs were not unlocking. The tires still spin freely as the transfer case is not engaged but both of the axles coming from it spin with the tires.

Having an issue w/ my 00 550. When I lock in the hubs there is instantly a noise, More of a squealing then a grinding. The truck goes in and out of 4x4 no problem and the noise is there locked in 4x4 and not locked in, as long as the hubs are locked in. I can't tell if the noise is coming from the 4x4 driveshaft but there is no noticeable play in the u-joints or the u-joints in the front axle. I did notice when I spin the 4x4 shaft by hand the passenger side joint spins slower then the driver, not sure if that's normal or could be the problem.

Trying to get my original auto hubs to unlock. Both are stuck locked. The dials turn but they won't disengage. Installing warn premium hubs tomorrow and the instructions say to unlock the hubs first. How can I do this if you can't unlock them?

Okay, pulled them and checked it all out.. Looks fine, disassembled the hubs and cleaned then greased went to reassemble them on the truck and they will not slide into the hub!?! What's the deal, is there a special trick to this?
It's a simple procedure, but it seems that the center shaft on the axle and the outer splined hub are not centered. thus binding, but why. It came out without a fight. I also have jacked up the front and wiggled it.

After a lot of reading and troubleshooting, I have come to know that it takes vacuum to engage and vacuum to disengage the automatic locking hubs on the Ford F series and Excursion. Most indications is that ~ 15" hg is required to engage and approximately half that much to disengage them. The mechanism that either engages or disengages them acts similarly to a ball point pen. The full amount of vacuum causes the mechanism to travel to it's limit, where the hub is engaged, whereas half the amount of vacuum applied only causes the mechanism to travel to its midpoint, which is where is should be for disengagement.
In my case, I have tested for vacuum leaks, none are present. I have installed new Ford OEM hub assemblies, a new locking hub solenoid and have tested the function of my vacuum pump. It draws about 13.5" hg of vacuum on the system. I do not have any issues with HVAC controls in the cabin of the truck. When installing the new hubs, I ensured that they are unlocked, the inner spline assy spins freely and once installed, the wheel shaft spins freely by hand. When I shift to 4WD on the dash, the hubs engage and all is well.
Problem I am having is when I shift back to 2WD, the hubs remain locked. I can tell as the wheel shafts are not able to be spun freely by hand. I have tried backing the vehicle, etc. No luck. Furthermore, when monitoring vacuum while engaging and disengaging 4WD, I can see that the full vacuum (~13,5") is applied when engaging. What concerns me is that only 3.5 - 4.0" hg is applied when disengaging. This is certainly not enough to operate the mechanism to the point of disengaging the hubs.
I have considered replacing the vacuum pump as I am only getting 13.5" hg of vacuum, however, when I research the replacement part, many have indicated that a new one only draws about that much, so I do not see the value in replacement.
Have any of you dealt with the same or similar problem and if so, what was your resolution?

And the vacuum pump was replaced.
