2004 fx4, transfer case engages, but front wheels won't engage. I assume the vacuum solenoid is stuck, any other thoughts?

Ford F-150 (2004-2008) :: Hubs Won't Engage Only Make Grinding Noise?
I have a 2005 F150 113,000 FX4. When I put the truck into 4x4 high the light comes on and the front driveshaft engages. Same with 4x4 low. the problem is that the hubs never actually lock. When I move forward in some mud or wet grass the right front hub makes this grinding noise like it is actually trying to engage but never does. Same with 4x4 low. I do not have any weird noises when I drive in 2wd.

About a month ago I bought a 2004 F-250 160xxx from a reputable Ford dealer here in town. The dealer performed a safety and emissions inspection, and spent about a grand on other repairs, as a condition of my purchase. Today I had it in the shop for an instrument cluster issue (at a different Ford dealer, closer to my house), and was told the vacuum lines were all messed up. Their write up is below:
"Check 4x4 operation. Transfer case shifts to 4x4 and 4x4 low. Front hubs do not engage automatically. Check vacuum at the hubs. No vacuum. Check the vacuum at the solenoid. No vacuum. Perform visual of the engine vacuum lines. There is no vacuum to the reservoir. Vacuum line is routed wrong from the fuel pressure regulator to the vapor management valve. There is other vacuum concerns. All of the vacuum line routing needs to be inspected and corrected."
The service rep told me it is questionable whether the 4x4 ever worked, although during the few weeks I've owned it, I could hear gears or other mechanical parts making noise which seemed to me to be in response to me turning the 4x4 electronic switch. She also said there was a vacuum line dangling loose with a screw in the end of it.
Before I contact the dealer where I bought the truck, I am planning my going-in position. But I wanted to get a sense of a) how serious of a problem this might be? and b) how reasonable it is that the dealer didn't catch this issue before I bought the truck while they were in their fixing other things?
The dealer who sold me the truck made it very clear that the sale was as-is, and I took it to my mechanic prior to purchase, though unfortunately he only had time for a cursory look at the engine. Obviously he didn't look closely enough to find this issue.
I'm not sure if I should ask the dealer who sold it to me to fix it, or ask them to allow me to return it, or sell it back to them, or if I should eat the cost of fixing it. How wrong would it be to try to trade it in for something else?
Ford F-150 (2004-2008) :: Front 4x4 Hubs Always Locked - Vacuum Is Too Low Under Hard Acceleration
I have an 04 F150 (4.6, auto, 4x4, SCrew) with 300,000 miles. Any success modifying existing 4X4 IWE actuators so they are always locked in?
My last set of actuators didn't last long My vacuum is too low under hard acceleration... Actuators partially engage leading to early failure.
I'd like to take an actuator apart, modify it so it's always locked in. Some loss of mileage? Other ramifications?
Ford F-150 (2004-2008) :: 4 Wheel Drive Is Not Working / Front Hubs Won't Lock In
(2004 f150 S.Crew 4x4) I noticed that my 4 wheel drive is not working. The front hubs won't lock in. The transfer case will go into 4 low but the hubs still won't lock in.
Anyway, I have pulled vacuum on both actuators and one of them won't hold. It's obviously bad, but is that why I don't have 4x4? It seems to me like it is not...
When I pull a vacuum on the actuator that does hold, it disengages the hub from the driveshaft allowing free-wheeling. Correct me if I'm wrong, but when the truck is running in 2wd, vacuum must flow to the actuators preventing the hubs from engaging? The actuator on the bad side is locked 'in' so the driveshaft always turns.
According to my train of thought, since the actuator has failed in the 'locked in' position, I should still have 4x4- What am I missing?
Ford Super Duty (1999-2016) :: Cannot Get 4x4 To Engage - Front Locking Hubs
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 F-150 (2004-2008) :: 4WD Not Working - Front Wheels Don't Engage
I have a 2006 XLT w/ the 5.4L engine. Manual transfer case, I'm wondering where to start looking for problems w/ the 4x4...the front wheels don't engage.
View 3 RepliesFord F-150 (2004-2008) :: 2005 4wd - Front Axles Won't Engage
I have a 2005 f150 and it will not engage the front hubs. It is a manual shift on the fly not electric. I have done some checking and this is what i have found so far. Pull the lever into 4H, dash light comes on, IWE's do not lock onto axle. Same for 4L. The transfer case does come in when lever is pulled into either 4H or 4L. Front end up on jack stands, engine off. Turn either wheel and axle turns with it as it should. Start engine, turn either wheel and it is free from axle, as it should be. so there is vacuum going to IWE when engine is on. Not sure what to check next. Is the vacuum solenoid on the firewall bad?? Is there something not getting activated when i pull the floor lever back?

2006 Lariat 4x4 Troubleshooting. My front wheels wont engage when I select 4H or 4L. No dash lights are ever lit.
I read up and understand how the system works and plan to replace the solenoid, transfer case motor and both hub actuators. I swapped out the solenoid and wanted to test that it was functioning properly so I followed the video below:
YouTube........
With the engine running and selector switch at 2WD, I pull the vacuum lines off and can feel vacuum at the supply. I then hook up just the supply line up (to the bottom port) and expect to feel vacuum at the other solenoid port (top port - what I would call the outlet) and cannot feel any vacuum.
This has halted my repair attempts as I am not convinced this is functioning and would pull in the actuators if they were functional. I know it's a small vacuum from a small orifice but I would think I should feel it by hand, no?
The solenoid's electrical connector is plugged in during this as well. I get the same performance with the old solenoid and the new. If I bypass the solenoid I can feel vacuum at the front wheel hubs.
Should I try a third solenoid? Seems unlikely I would have 2 bad ones...No OBDII codes at all. What to try next?

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 F-150 (2004-2008) :: Centric Hubs Failure - ABS And Brake Lights Are On
So I just installed my centric hubs that allow you to use 4x4it rotors. Along with some ebc rotors and pads front and rear. Well the "gear" that gives the signal to the wheel sensor is off center so now my abs and brake light are on cause it keeps losing the signal (checked with a solas pro). How well did they stand behind their product. Thought I should add they are still on my truck because my old rotors and wheel bearings were totally fried.

So from my previous post of might having a tranny problem or differential issue, it turns out that my front passenger side wheel hub is bad. Here is the odd part......the front passenger side wheel has some side to side play and it does make a clunk noise but it spins freely. On the driver side, there doesn't seem to be any play but it has resistance when spinning the wheels. Are both front wheel hubs bad or just one?

Ok, So, Im 40 miles from home stuck in ice and snow in a hotel.. (my wife works close by- thought it would be safer than driving in the 10 inches of snow we got 3 days in a row) so, I go to pick her up tonight and I engage 4hi.. I hear the click and the light comes on.. but no clunk of the hubs locking.. I drop it in 4 lo.. it shifts in low.. but the hubs are not locking..
I hear a ticking sound as I drive and when I put it in 2wd it goes away. I turn off the truck, turn the wheel hard both ways .. get out and I can physically turn the drive shaft and I hear the ticking in the hubs. If I read correctly when the truck is off these should be locked?
is it possible the vacuum is not releasing? I also get the groaning when I start up of the air diverter.. that im told is operated by vacuum.. so I am guessing I have a vacuum problem??
Ford F-150 (2004-2008) :: 2006 - Auto Hubs Making Noise / Cannot Shift From 2wd To 4H While Moving
I recently purchased as used 2006 F-150 Lariat 4x4 with 77K miles. I am having an issue with the shift on the fly, I had a vacuum leak that was causing the auto hubs to make noise on occasion but it has never allowed me to shift from 2wd to 4H while moving. I have replaced the IWE solenoid and repaired the vacuum leak but it still will not engage while moving. The light for 4H comes on but the hubs will not engage. The dealer where I purchased the vehicle is not a ford dealership and whey have been trying to solve the problem but to no avail.
View 3 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 Excursion :: 4x4 Selector Switch On Dash Lights Up Properly But Auto Hubs Don't Actually Engage
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.

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.
F Series :: 1995 F150 Manual Locking Hubs Won't Engage
Have a 1995 F150 with 83k with manual locking hubs. Haven't used them in almost a year. Today turned them to LOCK, normally very stiff, but this time easily turned with two fingers. Front wheels would not engage. Local mechanic put it on a lift, manually switched each hub from LOCK to FREE several times and they work fine now.

Truck shifts great from 2 to 4h to 4l and back to 2. However, at random times - any speed - usually when slowing down - I hear/feel something engage and there is usually a ratchet sound. I figured out its the 4x4 - if I switch to 4h then back to 2 quick, it stops. What the heck.
