Finally, after days of searching the web for P1876,P1832 DTC codes and getting absolutely no where you made it simple and even better, understandable. Thanx
Just set up forscan and had the exact dtc's show up on my 08 . I have the 4x4 lock up problem and this will undoubtedly save me a lot of hub disassembly looking in the wrong place. Thanks, I have 140K deleted and forscan says all is well!
My 2010 F-250 when locking the front hubs manually so it’s in 4 wheel low it stays locked in 4 wheel low. IOW when I move the dash control to 2 wheel drive and manually unlock both hubs, it stays locked up. Would you say by replacing the part in your video here (4 wheel drive solenoid) my transaxle will unlock? I dont have the software that you are using that shows the codes that are thrown
After manually unlocking, are you moving forward? The Manual hubs will stay engaged until you back up a little bit, it's just the way they are designed. If that doesn't unlock them, pull the vacuum hoses off the solenoid while they are engaged. You should hear air rush in. If you can reverse and they release, replace the solenoid in this video. All this solenoid does is allow a vacuum to be put on the hubs. When you move the selector in the cab to 2wd, it allows ambient air in to release the hubs. Since you are manually locking your hubs as mentioned in your comment, you might check the lines from the pump to the solenoid, and then solenoid to the hubs. They are plastic emissions type hoses that love to crack.
@@USAF99 Thank you for your extremely fast reply. After manually unlocking the hubs yes I moved forward. I also moved in reverse and the hubs stayed in the locked position. I would pull the hoses off to check to see if I hear air rush in but, it’s almost 3AM and we just experienced hurricane Helene moving through north central Fla. where I live and we are still experiencing 25-35 MPH constant winds so I wouldn’t be able to hear any air noise as it’s rather noisy from the tropical force winds. I’m totally unfamiliar with the pump you refer to. That said I could follow the plastic air lines back to the pump in order to inspect to see if there are any cracked lines. FWIW, I’ve always been under the assumption that in order to engage/disengage 4 wheel low, that the hubs have to be manually engaged/disengaged. Are you implying that my truck should be able to engage/disengage 4 wheel low w/o having to manually lock and unlock the hubs? Thanking you in advance!
@@shakin_jakewilson5247 No worries, having lived in the panhandle of FL, I know your plight. I was stationed at Eglin. Be safe! So, if you have these parts, then yes, you should be able to shift in and out of 4WD auto and low sitting in your driver seat. If it has never worked, either the vacuum seal in one or the other hub is leaking, the plastic lines are shot or the pump/solenoid is shot. When you turn the key on, you should hear your fuel pump and a little buzzing up near the engine compartment fuse box (behind degas bottle, mounted over the fuse box). If you don't, start troubleshooting the little air pump. If that works, but isn't engaging/disengaging, troubleshoot the solenoid mentioned in this video. Remember, it might be as simple as a fuse.
@@USAF99 thank you for all of the tips you provided. Yeah, you’re right, either the solenoid is not working correctly or, I have a vacuum leak somewhere, a chore I do not relish investigating. That said I found an answer (or workaround) which was revealed to me from BC Cruiser over on the diesel stop forum. I posted a query over there too and he told me to shift into neutral and the transaxle will jump out of the locked mode my truck found itself in. I read his reply at 3 AM over the past weekend so I opened the truck, then I had to set the parking brake as where I had parked, was on an incline. So with the motor running (IIRC) I shifted into park and sure enough, I could hear something unlocking. I can’t tell you if the sound (pop) I heard was both hub actuators unlocking in unison or what but the yellow 4 wheel low light ceased to be illuminated and the truck was no longer stuck in 4 wheel low. Hallelujah!, I had a roadworthy truck again. It doesn’t bother me that I have to manually lock and unlock the hubs into and out of 4 wheel low, I can live with that but what I don’t understand (which is okay) is why that I have to go into neutral now to get out of 4 wheel low whereas prior to up to now, I never had to shift into neutral to get it to pop out of 4 wheel low. I guess it’s going to have to be a mystery to me but I’m okay with that. So long as I can go into and out of 4 wheel low, I’m fine with that. Thank you once again USAF99 for all of your help, it’s truly been much appreciated
If you want quick and obtainable, the box stores sell a Doorman 600402, the vacuum control solenoid. It's right up on the right side core support/radiator area, very easy to access. Or you can go to the ford house and ask them for the 4x4 vacuum control solenoid.
3 quick questions. You said the first code then only word the second half of the second code but just to be sure do you remember the actual second code by number? You said they come together. #2 did you use oem parts? Has that code come back at all or has stayed off since the video? Thanks
I would have to find a truck that has some, mine does not. Easy way to tell if yours is bad - take the oil cap off and turn it over (flat part down with oil weight written on it). Set the cap on the hole you just created (where it normally goes, but upside down). Start the truck. If the cap flies off, you have excessive blowby/crankcase pressure.

Great video! I'm still looking for the part number on that which is supposed to be the easy part
Thanks for help my fren Godbless"you
Great video thanks!
Hey man, how many miles on yours ? I've got 170000 fully deleted runs amazing not one problem in last 12 years
176k, same, no problems!
SSLC what does your blow by look like? Mine tilts the cap but does not blow it off

What was the part called? I have the same code and mine will work in auto on the hubs but not on lock. Hoping this fixes it.
If you want quick and obtainable, the box stores sell a Doorman 600402, the vacuum control solenoid. It's right up on the right side core support/radiator area, very easy to access. Or you can go to the ford house and ask them for the 4x4 vacuum control solenoid.
Does the truck need to be lifted so i can do this job? Thanks for video!
Nope, you don't even have to bust out a jack!
I A CUESTION WHAT WAS THE SYMTOMS ON CODE 1876 PLEASE THANKS. I WAIT FOR YOU ANSWER
The truck would not shift the front axle into locked using the vacuum locker.
Is this the same on an 05 F350?
It "SHOULD" be. I'm hesitant to say yes as I can't see your truck...obviously.
3 quick questions. You said the first code then only word the second half of the second code but just to be sure do you remember the actual second code by number? You said they come together. #2 did you use oem parts? Has that code come back at all or has stayed off since the video? Thanks
It's been quite a bit since this vid, I can't remember the codes- I can however tell you that yes, I did use OEM and no, they haven't come back.
Thank you
Can you post a video of blow by?

USAF99 well i have now put a new motor in from choate engineering lol
nice thank you
