Ford Super Duty (1999-2016) :: F250 - Hubs Won't Unlock / How To Get Them Functional
I just got a 99 F250 PSD, it had not been in 4wd in a while, now the hubs won't unlock.
My 01 F250 seemed to have strictly manual hubs. Turn right to lock, left to unlock. They may have been aftermarket, but on by the PO. Do I need to put some new Warns on the 99? Or can I lube then up and get them functional.
Ford Excursion :: 911-4 - 4x4 Hubs Reinstallation?
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.
Ford Excursion :: Stuck In 4x4 With Hubs Locked
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?
View 6 RepliesFord Excursion :: Auto Hubs Won't Disengage?
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?

I bought a 2001 Excursion Ltd 4 years ago. A previous owner put Warn Premium hubs on it, which I would have eventually done myself.
I got stuck a couple of weeks ago and tried to use my 4wd. Nothing.
A friend suggested I replace the Transfer Case Motor as it can go out if you don't use it. I got that done today but I still don't have 4wd.
I can hear the transfer case shift and see the drive shaft spinning, but the front tires don't spin.
I thought it was the PVH solenoid, but discovered the Warn locking hubs don't use the vacuum and it has been disconnected/plugged.
Ford Excursion :: 2002 - Replacing Manual Hubs?
So I will be replacing the manual hubs on my Ford 2002 Excursion 7.3 diesel 4x4 with the WARN 38826. Just a few questions. Will I need to use the small snap ring? Also, do I have to worry about blocking the vacuum lines going to each stock hub? Any videos or step by step instructions with pictures for my truck.
View 12 RepliesFord Excursion :: Retainer Rings Popping Off Hubs
It has done this to me several times--both sides. Still learning about these auto lock hubs--though I did get them to "auto lock" now. It looks like the hub lock is not going as far down and creating depth for the retainer ring as I have seen on some youtube videos. I have taken out the hub lock and cleaned the outside of it before and cleaned its seating area but I have not disassembled and cleaned the hub locks themselves--had this about 4 months.
Last night, I had the right front tire off checking brakes. When I go to put the tire on--heavy mothers--I had it hanging on the outer part of the hub lock (installed of course). We're talking seconds here. I pick the tire up to put it on the lugs and the inside of the rim hits against the retainer clip area and it pops out. Why these frigging things keep popping off or hub not seating fully? Is there a reason these have el cheapo dryer vent clips instead of screws or something else?
Ford Excursion :: 2000 - Hubs Locking Warning
The 2000 X I have has Warn locking hubs on them. Just to be clear, I'd need to switch them to 'lock' then choose either 4-Hi or 4-Low on the dash in order to engage the transfer case, correct?
View 8 RepliesFord Excursion :: 2003 - Manual Locking Hubs Won't Turn / Stuck?
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.
Ford Excursion :: 2000 - Pulling And Unlocking The Auto Locking Hubs?
I just recently purchased a 2000 Excursion and had some questions up in another thread. After doing some diagnosing....I have a couple of questions about the auto locking hubs. The problem I have is that even with the vacuum line disconnected from the knuckle and no vacuum...the hubs won't unlock in auto/2wd. I confirmed that the knuckle and the hubs will hold vacuum when I hooked my vacuum pump up to it and it held vacuum (the fitting should be clear as I heard the hub making some sounds). I'm getting ready to pull the hubs to clean and re-grease them. My question is that being they are still locked....will it be any harder to pull them off the spindle and after disassembling them/cleaning them.....when I re-install them....will they be unlocked by default after putting them back on the spline as they have been pulled apart and reassembled?
View 14 RepliesFord Excursion :: Rattle Coming From Hubs When Driving Over Rough Or Broken Pavement
Swapped for Warn standard hubs a few months back when the ESOF's turned out to be trashed.
Since then, I've noticed a rattle coming from the hubs when driving over rough or broken pavement. I've checked the outer caps and they're good and snug, proper amount of grease inside, and the hub itself is completely secure.
Do aftermarket hubs have tis issue? It's not critical, but on cooler evenings with the windows down it sound like a rattle trap unless the roads are in good shape. More of a pet peeve I suppose, but still curious.
Ford Excursion :: Keeping Front Hubs Locked And Switch In 2wd Position For Everyday Driving?
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.

My Excursion is having an issue with the 4x4 system. The. 4x4 selector switch on dash lights up properly for 4x4, but the auto hubs don't actually engage. The hubs will lock only if I manually lock the hubs. I can hear relay click, so I don't think its electrical. The hubs had new o rings installed when I did front ball joints a few thousand miles ago, and the 4x4 worked fine up until today.

On my previous vehicle (2005 Avalanche), when I unlocked the doors, the tail lights and parking lights flashed to let me know that the signal was received and the doors were unlocked. I noticed that the Excursion doesn't do that. The lights flash on "lock" but not on "unlock". It's a nice feature to have, especially at night.

I just got an Ex and am going to take it out next weekend and am trying to get it all squared away. What I am wondering is if there is a way to program it so all the doors unlock when shutting off the vehicle. Currently the drivers door will but I have to hit the unlock button to let everyone else out.

This afternoon the Passenger door lock would not unlock, with switch, key fob or door pad,you can hear it and the lock rod moves a little but will not unlock. Now it won't lock or unlock, you can hear the actuator and see the lock rod move a little but it just won't get there. Should I get a part in hand before I tear into it or could it be a easy fix with no parts. 2002 Ex XLT 4X4
View 3 RepliesFord Excursion :: Door Unlock Fail And Flashing Battery Light
I have been having an intermittent door unlock switch failure... The driver side and passenger side unlock doesn't work but the lock does... It has been intermittent, but now seems consistently not working... This is now accompanied by a flashing battery light on the dash, which I've never seen before....as well, the dome lights have stopped working, could be bulbs, haven't checked, but i replaced them within a year ago...
I guess my question is.... Would a flashing battery light be connected to switch not working? Is it likely to be the module since both passenger and driver side unlock function failed at the same time? I doubt both actuators would go at the same time...The other odd thing to tag on to this is a month ago my fuel gauge went dead... I keep wondering if there is a common connection....
