Ford Super Duty (1999-2016) :: 2001 F250 4x4 - Auto Lock Hubs Are Not Working
2001 F-250 7.3. The auto lock hubs are not working on the truck lock hubs in and all works fine. First thought is the vacuum system has a leak or something of the sort. Had truck at the shop they are telling me the GEM module controls the vacuum to engage the auto hubs and the signal is not coming from the GEM and it need to be replaced. It was the GEM causing the problem.

When I turn on the headlights of my 2004 sd diesel dually the console readout dims to the point I can't read it. I know about the intensity wheel but it does not have enough to overcome the auto-dim feature. Can the auto-dim be disabled, ripped out, sent to Iran, threatened with a .45? Anything to get rid of it.

2004 Ford F250 CC 4x4 6.0L
Took the family down to the beach today. Had some tough sand to get across in a few areas to move away from the crowds. Got a little dicey and the truck got stuck in 2WD. Switched to 4WD but back tires kept spinning. Couldn't figure out why and the truck started to dig deeper in the sand. Got a little nervous and I didn't want to start the day off with having to get pulled out.
Got out of the truck, locked the hubs in manually and I was out, no problem. Left the hubs locked until we left the beach and back on pavement.
What might be the problem and why the "shift on the fly" switch on the dash didn't seem to engage the 4WD? I even tried to switch into 4L and back to 4H (truck in neutral, break pedal compressed) and still no workie. Only manually locking the hubs would engage the 4WD.
Ford Super Duty (1999-2016) :: Front Hubs Not Auto Locking
My hubs will not lock when put into 4x4. I disconnected all lines from the solenoid to both hubs and tested them for leaks... All good there. I put a gauge on the lines at both hubs one at a time while the other is still connected and get no reading when switched into 4x4. I checked for vacuum right out of the solenoid, and I get 2inHg when switched into 4x.
The vacuum pump kicks on every time I start the truck, even if I just shut it off and re-start right away. There is no delay when switching my ac/heater controls to different settings or vent locations. So I know there is vacuum. How much vacuum I should be getting out of the solenoid to the hubs?

Ford Super Duty (1999-2016) :: 2007 - Auto Locking Hub Not Engaging?
I'm trying to figure out why my auto locking hubs do not engage. To isolate the problem shouldn't the hub engage if a vacuum is applied to that hub only? A solid 18 inHg is maintained at that hub for over 10 minutes but the selector will not rotate, which suggests to me the seals are OK. What then might be the problem?

I am changing my 99 f250 4x4 from auto to manual tranny. I am just looking for pics of where the hydro line runs. I don't want line rubbing something and ruining line. Like does line run under the cab wiring harness? Like between wiring and firewall? Where on firewall does reservior get mounted usually? Are the holes all ready there for it that I am not seeing?

I just replaced the ball joints on my 02 excursion and I can't get the locking hubs to seat far enough in so that the retaining ring keeps them in place. The ring seats but then works out as I'm driving. There is something keeping the hub from sliding in far enough so that the ring/clip can set deep enough in its groove. What's causing that? Its happening on both sides.

I have a 1 week old 2013 Super Duty. Super Cab, Short Bed, 4x4.
Immediately I noticed on the drive home that the truck likes to wander back and forth and needs constant correction. It was really windy on the drive home from the dealership so I just chalked it up to the wind and didnt worry about it. Now a week later , its still doing the same. I have a 2011 F-150 and also a 2006 F-15 that I get to drive regularly and they definitely track straight and have no problem going down the road without constant correction.
ALSO, I noticed that my Super Duty DOES NOT auto center itself after a turn. Is this normal?? I mean after I make a turn, the steering wheel doesnt try to go back to center. I noticed that right away because I went around a turn and loosened up y hand's grip on the wheel expecting the steering wheel to slide through my hand as it went back to center like I am used to with my F-150s....
So in summary, my new truck wonders all over the road, much more than my F-150 and also doesnt auto center itself. Is this normal for these trucks?
Ford Super Duty (1999-2016) :: 2000 - Auto Door Locks Don't Work
I just bought a 2000 super duty F250 Triton V10 and the auto door locks don't work. They try to work as in tug an eighth of an inch but won't successfully engage or disengage. Thought it might just be the switch inside the door handle but they don't work on the passenger side etc either.
Also two days after I bought it I found out first hand that these motors spit out spark plugs and i had to replace the plug and coil. I was told that there is a tool that I can tap out the heads with and then put inserts in so i no longer have this problem. Where do i get that tool and how much are they? Is it true that pulling the plugs can strip out the heads because i bought all new plugs for the truck and was then told that it will strip out the heads.
How many quarts of oil does this engine hold and should i use a certain type of oil? It has high miles but purrrr'ss like a kitten.
Ford Super Duty (1999-2016) :: 2000 F350 - Cannot Remove Auto Locking Hub
In my attempt to remove the auto locking hub on my 2000 F-350 4x4, I found that it would not slide out. I removed the retaing clip and the hub should of be able to come out with a couple wiggles, it seems to have seized inside the hub. I tapped it with a rubber mallet on all sides. Any thoughts as to other alternative methods of removing the hub locker ?

I was using 4x4 High the other day and it was working just fine. Now today, I was at my first parking lot to plow and used the ESOF to shift into 4x4 High and it did not engage with the hubs being in auto mode. The lights on the dash show up indicating that I am, but I am still in 2wd.
If I manually lock the hubs, it engages 4wd high. I tried the same thing using the ESOF to switch over to 4x4 low and it does NOT engage either.
I also noticed that heater blower was switching over to full defrost even though I had it set on the floor setting (manual heat climate *****).
Does this sound like a vacuum leak? I haven't had a chance to test the lines yet. Btw, this is my second work truck and not the one listed in my signature below. It's a 2006 f-350 6.0 xlt.

2009 F250 Super Duty 4X4 auto lock hubs not working. Indicator lights on dash come on but will only go into 4 wheel drive when hubs are locked manually.

View 5 RepliesFord Super Duty (1999-2016) :: Clunking In Front End When Turning Hard Even With Hubs In Auto
So I noticed the past few days my 09 F250 was clunking in the front end when turning hard even with the hubs in auto so I knew there was an issue in there somewhere. This morning I took the jack and found the passenger side would not release no matter which way the lock was turned. Pulled the locking assembly out and found a couple of the pieces of plastic cage broken (truck has 250k miles) which is to be expected I guess but the locking ring that holds the inner piece that slides over the axle stub was off and hanging next to the c-clip on the axle.
So with the plastic of the cage already being broke and the mileage on the truck it's clear I need a new lock for that side.
Here's my dilemma, I have to deliver a conference room table 200 miles away tomorrow morning that they need for meeting tomorrow afternoon at 3:00pm. I cut the rest of the plastic pieces and took the gears out leaving just the cover with the diaphragm and put it back on the hub. I can't come up with any logical reason why I can't drive the truck this way but just want to bounce it off the experts here before I take off on a 400 mile trip in the morning. The only thing I can come up with is if I were to engage the 4wd the vacuum might suck the auto-lock diaphragm in and pop it but otherwise I can't find any reason to not run it this way, the hub is still sealed up and free-wheeling just like if it were in 2wd anyway.
Ford Super Duty (1999-2016) :: How Does ESOF Locking Hubs Work In Auto Mode
I took apart, cleaned and lubed my hubs. My question is: how does the vacuum make the gears work?
Does the vacuum force (suck) the nylon assembly to push the outer gear towards the center of the truck, sliding on the inner gear thus engaging the teeth so that the axle shaft turns the hub?
When the vacuum is gone, does spring pressure pushes the outer gear away from the center of the truck thus disengaging the teeth from the inner gear and allowing the hub to free wheel?
Is this vacuum source constant during 4wd and not present during 2wd or do I not understand how the system works? I have read about a “vacuum pulse” that locks the hubs and another pulse that unlocks the hubs and this confuses me.
BTW, I like the way the Auto lock works. I had a set of Warn Auto Lock hubs on my 78 CJ. They worked on the principle of a set of roller bearings that would lock (pinch) when there was torque coming from the drive shaft. There was no vacuum involved at all. The down side was that when you coasted, the front hubs would be in two wheel drive and so you would not get the engine braking on all 4 wheels. These ESOF seem to have solved this problem.
Oh, I should probably tell you that I just purchased my 04 F250 SuperDuty 4x4 with the 6.0 diesel, just had it a week. It has been 18 years since I owned a 4x4. Before this I owned an 87 F250 2wd with the 6.9 diesel.

My F350 4x4 won't go into 4 wheel drive unless I get out and take them out of auto and put them in locked position and when I have it in lock mode it seams to work like it's in auto mode, when I put the switch on the dash in 2wd, it seams like it's only driving the back wheels....

Only got a click when turning key, in Park or Neutral. Made sure I had >12.4V from battery. Jumped starter solenoid with a remote start switch across main power line to starter and the 's' post, crank pulley almost moved, but didn't rotate. Removed belt, all pulleys rotate, but could not budge the crank pulley with a short breaker bar/socket, rotating clockwise from front. Removed starter, that upper bolt is a super pain! Not even sure I'll get it back in. Jumped starter solenoid again on the bench using a battery and jumpers, not the best connections, starter hesitated little bit, but opened up fully a few times, so I'm thinking it's ok (even though the power line from the solenoid to starter motor needs re-taping). Tried rotating flywheel from starter hole, no good leverage point, but no movement. Before I re-install the starter, how much torque should I be putting on the front crank pulley? Some say it should move easy enough cause the starter isn't that powerful. Others say remove the spark plugs to reduce compression? This truck is new to me, so I unfortunately have no history.
View 1 RepliesFord Super Duty (1999-2016) :: 2006 F250 Auto - Trans Won't Shift Into Overdrive?
I have a 2006 F250 with the 6.0 PowerStroke and automatic transmission. I just purchased this truck at an auction about a month ago.
Today I notice the transmission is not shifting into overdrive. No warning lights. If I press the tow/haul button in no change but the tow/haul light does come on. If I press it again (to turn it off) the tow/haul light goes out but still the transmission will not shift into overdrive.
This leaves me at about 2000 RPM at 68 MPH. I just had a Ford dealer perform Transmission service last week. (20,000 miles after the last recorded service.)
I am already not happy with the service I received at the dealer so I am really hesitant to take it back to them if it is something not related to the transmission service they performed.
