Ford Super Duty (1999-2016) :: F350 Won't Go Into 4 Wheel Drive - Auto Locking Hubs
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....

I recently purchased a 2003 F350 FX4 Dually with the 7.3L Diesel. It has locking hubs and electric shift in the cab.
I have had locking hubs before that you had to engage to shift into 4 wheel drive and I have had trucks without locking hubs.
My truck didn't come with a manual, so I am looking for instructions for the proper use of this system.
Ford Super Duty (1999-2016) :: F250 V10 - 4 Wheel Drive Hubs Are Not Working With The Vacuum
I recently picked up a '99 F250 Super Duty with the 6.8L V10 for a song.
The 4 wheel drive hubs are not working with the vacuum. If I use the manual lock on the hubs all is well. I ordered the Innova 31703 CarScan OBD2 + OBD1/ABS/SRS Scan Tool. It says it does Trans codes. I am hoping it will cover the 4 wheel drive too.
Maybe related, the heat is always on. Meaning I feel heat at my feet when the temp dial is cold and fan is off. I can't find the heater control valve to check the vacuum line.
Ford Super Duty (1999-2016) :: Seized Locking Hubs
Back in March while still plowing, my auto locking hubs wouldn't stay engaged. After talking to the local Ford service shop they told me that it was moisture in the vaccum lines and that it had frozen. They told me to manually lock the hubs and bring it in to be repaired when I had time. I made a appointment in the middle of May and finally got it in last week. Now the hubs are seized in the locked position and they will not warranty the work or parts because they say it was caused by the salt from our roads. Does this sound right?

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) :: Manual Locking Hubs Code
I just ordered '00 F250 SC 4x4 SWB XLT with the factory standard manual hubs. The hubs show up on the vehicle order confirmation as code "21M MAN LOCKING HUB". I can't find this code in the ordering guides anywhere but kbb.com shows this code as "Manual hubs delete. Required with 213 shift-on-the-fly". I want the manual hubs. I think ##### is incorrect. For my piece of mind, could someone who has also ordered the factory standard manual hubs verify that the code is indeed 21M. And for those who ordered shift-on-the-fly, could you verify that 21M does NOT show up on your order confirmation...

I am considering buying a 2001 Ford F250 Super Duty XLT 4x4 V10 engine tomorrow. I am hesitant because I cant get the 4x4 to engage. It goes into 4x4 low and high and the front driveshaft spins but it wont engage the wheels. One side locking hub locks but the other side the locking hub is cracked off and so I there is no way to turn to lock that side. I will of course replace the Locking Hub ASAP if I buy the rig but my question here is, if one side is locked should one side of the front axle spin, meaning if only one side Locking Hub is locked should that wheel turn and the other not? Both are not turning but as I said the driveshaft is spinning.
I don't know if both sides need to be locked in order for the front wheels to engage while in 4x4 high or low. Or if one side should engage if only one side is locked; the wheel that's locked of course..

Ford Super Duty (1999-2016) :: F350 4WD With Locking Hubs - Shimmy / Vibration
I drove my pickup on mostly dry pavement the other day with it in 4WD and the hubs locked. I got a bit of shimmy/vibration which quit after about a mile. When I got back on ice, the 4WD wasn't working. I assumed the transfer case or locking hubs had failed. Today I got it up on jack stands, put it in 4WD, and locked the hubs. Everything seems fine. What might have happened when I couldn't get 4WD to function.
View 2 RepliesFord 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.
Ford Super Duty (1999-2016) :: Growling Sound While Turning - Locking Hubs Or U-Joints?
Today was the first time I have locked my wheel hubs in and used 4 wheel drive. However when I did all this i noticed that when I turn there is a growling sound but only when turning. It does not make the sound when unlocked and in 2 wheel drive.

I've noticed my front axles are rotating all the time even when the hubs are in auto and supposed to be unlocked when in 2wd. Is there a rebuild kit for these so they will unlock the axles or do I need to buy new locking hubs?

My 2010 F350 shudders when turning right. From what I read it could be the auto locking hubs not dis-engaging or sticking in the locked position. Tutorials show it's pretty easy to pull the auto locking Hub out taking out the three screws holding it in place. My questions is what type of grease do I need to apply to the auto locking hub once I have them out and determine that is what the issue is?

I have a 2013 F250 which has both the Manual and auto locking hub feature. I tried to plow my driveway this morning and after making one pass I put the truck in reverse and could not back up my steep driveway. The truck is showing locked in 4x4 on the dash, the 4x4 control is in high lock but the front wheels will not turn. It has been very cold here lately (-30) and I'm wondering if the vacuum lines for the auto locking hubs have frozen. I have switched the control out of 4x4 and back in several times, and it does lock in again, but as soon as I put the truck into reverse, they unlock again. The hubs are covered with ice and snow right now so I have not yet tried to manually lock them.

So after eight years my Warn premium hubs have taken a crap and developed major play internally. After speaking to Warn warrenty department and sending videos they will replace them according to the lifetime limited warranty. Problem is they sill not send out new ones until they receive the old ones, so I was told from time i remove mine and send them back and get the new ones it will be two weeks maybe a few days more, there is no snow in the extended forcast and im wondering what damage could occur with me funning the truck everday to work etc with the stub shafts just hanging there?

Today I put a new shifter tube in a 02 f450. Everything works well, but the key won't come out and the steering wheel won't lock. Was told there is a button to push by the turn signal side but don't see any. Looked around top and bottom of column and didn't see anything out of place. Also found a black wire with a pink strip not connected to anything. Touched the wire to the column and key dinger sounded. Where should this wire be connected?

Checked the EOF vacuum lines and pump but still have a problem. The EOF works and locks the hubs when I switch to 4x4 high, Easy to feel when you turn the wheels but it will not go into low. The light on the dash does not light up the word "low".
