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....

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?

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) :: 4 Wheel Drive Locking Hubs?
My 2009 F-350 4x4 has a front wheel option of Auto or Lock ; I think I understand the Auto option but under what circumstances would I lock the hubs and is it safe to leave them in the Lock mode when traveling on the highway?
View 5 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?

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) :: 2013 F250 - Vacuum Lines For Auto Locking Hubs Frozen
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.

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?

View 6 RepliesFord Super Duty (1999-2016) :: 2006 6.0 F350 4x4 Auto Hubs Will Not Engage
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.
Ford Super Duty (1999-2016) :: 2008 F350 - Automatic Hubs Not Working
I have a 2008 F350 and my automatic hubs won't work, also when I turn the AC on there is heat coming out of one side of the vents. I am assuming this is a vacuum leak somewhere but my vacuum pump doesn't run steady? I thought if there is a vacuum leak then your pump should run steady? The 4X4 works fine by locking in the hubs

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?
