Ford Super Duty (1999-2016) :: 2004 - 4x4 Auto (shift On Fly) Not Engaging?
Jun 15, 2009
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.

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 have a 2000 f250 CCSB 4x4 with the ESOF auto hubs. The auto hubs won't engage automatically. They work fine manually. The transfer case is engaging and correct lights are coming on. There is a little bit of vacuum coming from the vacuum switch but it doesn't seem like much to me. All the dash HVAC controls work fine though. I Lubed and cleaned inside the hubs according to Guzzles directions.
While torn down, I blew through the vacuum port on the outside of the hub and there was little to no restriction. I don't think there is enough vacuum to pull the hubs, but is that possible if all the dash controls work fine? What pressure should it take to engage them? My next step is to pick up a vacuum pump and see if I can engage them with it.

Yesterday I was parked on an incline with my front wheels on gravel and the rear wheels on wet grass/mud. When I tried to go, the rear wheels started spinning. I then switched on the low 4x4, and tried to go. The rear wheels continued to spin, but the front did not turn. I had new wheels installed, that has a cap that covers the manual locking hub, so I couldn't turn it to lock the hub. What should I look for to fix the problem?

My 2011 F350 is not engaging 4wheel drive from the dash switch. When I turn it to either hi or lo it says "shift in process" but no 4 WD. It will engage manually from the hub lock, no problem. I know very little about 4wheel drive but am otherwise mechanically knowledgeable.

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.

After reading the book, I'm afraid I still don't understand. When the hubs are in AUTO, & the shift on the fly selector is turned to 4X4 high, or 4X4 low, is the truck in 4 wheel drive. What happened to free or lock.

2012 6.2 XLT 50,000 miles with manual single zone controls. I haven't had time to work on it yet, but it seems that my AC compressor is not engaging. The dash controls light up normal, fan comes on, etc. I am just looking to see if there are any common failure points. I know it COULD be low on charge, clutch could be bad, etc. I am just checking if there is a common failure with these trucks AC system.

I tried searching and googling but came to no results, unless its like similar trucks. How do the 4x4 shift remove? I have an 04 F250 and someone decided to put the shift on sideways so the 4HI and etc read upside down before I purchased the truck. Do I just rip the thing off?

The kid at body shop called, he has the cab ready to swap onto the 04 gas job except for the shifter cable at the trans. I have never done one either, and do not know how to take it off. I thought it was like the old trans where it was in a plastic grommet, but the cable almost looks like it is grafted to the trans. How to get the cable off the trans shift arm?

Pump works fine. Replaced pvh. Won't go into 4wd hi or lo no matter what I try. Even with them in lock. How do I know if hubs need replaced or just hub locks?

I have a 2002 Ford Superduty. I recently had installed a BDS 8 inch suspension lift. I also had the upper and lower ball joints replaced. All this work was done by a certified garage. Today i went to pull out my boat from the ramp, turn the switch inside the cab to 4x4 high. The light came on but 4x4 did not engage. As i pulled the boat out of the water the rear tire spun in the sand but the front did not. As i cleared the ramp and on level ground i turn the switch off and back on i heard not but the light can on. With the 4x4 light on i turn the wheel and pulled forward i noticed no hopping as when a truck is in 4x4. Initially when i turn the 4x4 switch on i hear a clunk up front but not after. Drove home drive train appeared fine no noise.

Truck was running fine up until now. After the WTS light goes out, I crank it and.... nothing. It doesn't even try. It's not a battery problem. I have 12.6 V from each battery before and after cranking. The lights are bright, the horn works, the dash lights are strong and bright all both before and after cranking. It just doesn't want to engage the starter. I tried my backup key as well, thinking it might be a problem with the PATS. No dice. Where to start looking?

2006, ESOF. Noticed the front hubs aren't engaging but the transfer case is. What should I check?

My 4x4 on my 2000 model f350 will not engage. The light works, comes on briefly on startup of the engine. When I flip the switch nothing happens. When I jumper the relays nothing happens. I do not have the factory hubs, they r warn hubs and the vacuum line to them is capped off. How to figure this out on why the 4x4 will not engage?

Got in my truck this morning and everything worked fine, no problems. Arrived at my destination and parked. Come out about two hours later start the truck and my A/C wont blow air, My truck is an 05 lariat so it has the climate control A/C. Everything was working fine it just wont blow air, When i turned the A/C on and off i could hear/feel the small thump of the clutch engaging on the compressor. I am thinking the blower fan just went south? or maybe something stupid that controls the blower fan? Summer is in full swing here in central florida, temps are 95+ not including the humidity...

I have a 2001 F250 4x4 and the ESOF switch not engaging hubs, currently I have no 4x4 lights coming on in the cluster when i turn the switch. I am not experiencing any of the vaccum symptoms that most people are suggesting. I When I turn the switch i also do not hear any relays clicking. Relays have been tested, and i waited for the 45 second transfer delay that the manual mentions. ESOF switch has power, and is working properly (I know because I bought a new one in attempt to fix the problem) Basically I have no responses from any of my 4x4 indicators or parts.

I'm in the process of changing my shift motor on my 04 f350. I can't get it off because of a broken bolt. The previous owner must have done this before, and snapped the head and some of the shaft off, so it's basically an alignment pin that's recessed into the hole on the motor. For some reason it's holding the motor on, even though I don't think the hole is threaded. Any way to get it off. I'm thinking that taking a MAP gas torch to the casting on the motor may be my best bet.

Well replaced my u-joint on the passenger side along with the large knuckle seal. to say the least.. a nightmare. Got it all put back together and now my auto 4x4 is not working. dash says it's in 4x4 but it's not engaged. Worked fine before this little adventure. It's a 2006 250 superduty gas....

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.

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?
