I agree. Luckily I can do all my own work but when the upper oil pan started puking and I still had warranty I brought it in. Next oil change I literally removed the drain plug by hand, they charged ford for a coolant flush they never did and whined on the work order that the BDS lift made the job harder to do. A few months later the truck would periodically lose major power so I again brought it in but was informed the warranty was cancelled. Since I pretty much cringe at a dealership touching my truck I went home and got to work on it. Luckily for me not all dealership techs suck and one posted a video of a problem he found that had a few of the same codes which was the harness rubbing against the egr cooler and shorting or grounding out. Now I don’t miss any of his video’s, thanks AROD. Oh ya and MSA ford sucks big time, if you take any pride in your vehicle don’t go near the lying rats 🐀. I could say more but this comment is already ridiculously longer than the amount of time my truck sat in their lot before they even touched it the first time I had it there

Great video. My 4x4 wasn’t working after this video I found the vacuum lines was broken and I fixed. Thank you for this video very helpful!!!

[@ChrisR1270]

Remember the days when you reached down and pulled the lever into 4-high after locking the hubs? No muss, no fuss unlike today.

[@rafeeqfoster4296]

I now know what that line is for. Mines broke off and I couldn't figure what it was for and I finally typed in the right wording. Thank you for this! My truck is a '17, the dial is pretty hard to turn, but I haven't had issues shifting until my passenger side hose broke.

[@mlieser1230]

Both Dodge and GM abandoned locking hubs long ago. I'm glad that Ford still has locking hubs and that they can still be manually locked in the event that the vacuum system fails. I just can't see turning the front axles and driveshaft when not in 4wd. My motto has always been "Lock and Free = Economy".

[@turbotonye-4124]

I totally agree with you. Locked or unlocked. None of this auto hub B.S.

[@chadh6899]

Very nice video ARod and really clear explanation of the functionality of the locking hubs/vacuum system.

[@PowerStrokeTechTalkwARod]

Thnks pal

[@Chillguydrew]

Thank you major help!

[@johnsullivan8527]

They really weren't the same all the way back to 7.3L days. The older ones through i think 2010 were pulse vacuum hub lock. 2011 and newer are constant vacuum hub lock. Much simpler system. PVH hubs were a pain in the ass! Love the videos. Keep it going!

[@elf94z]

Yeah i was thinking the same thing! i did stay with the factory pulse hubs but disconnected the vacuum after one of the hubs stayed locked in after its ‘lock & unlock’ cycle they do on every startup

[@JMSynthetics]

Im surprised Ford has stayed with this setup as long as they have. I remember replacing them with manual lock out kits on 7.3s back in the day when the customers didnt want to pay for messing with the vacuum setup. We would replace with the warn manual hubs.

[@packoutjunkie160]

Yep I agree. Warn Premiums on my 99. My 16 I bought a manual gear shifter for a reason.

[@daddydiesel5889]

I put mile markers on my 03 7.3, pretty sure Ford wanted a boat load for those hubs…at least at the time. I always feel better just locking them in anyway if you know you going to be wheelin!

[@akbychoice]

Or the grease in the hub is dry and needs cleaned and replaced so the locking parts can move in the hub.

[@chrisgroves9829]

I wish I lived in your area Arod.I would take my truck and tell my buddy’s to take their trucks there to see you. Thank you for explaining things in detail.

[@crbourret]

My Auto 4wd hubs on my F350 stopped working. I just checked and found a vacuum line to the right front knuckle had come undone. Plugged it back together and it's fixed! Thanks for the tips man!!

[@spartanoverlanding300]

Mine was in the shop for over 2 months due to lack of parts needed. Good thing for the manual hub option

Pretty sure I need seals on my 06. Air likes to switch up to defrost and auto hubs don’t work anytime. At 257000 miles on a farm truck I won’t complain. Thanks for sharing!

[@21psd]

Classic example of, the wheels spinning but the hamster's dead! lol I had this problem back on my 2008 where that spaghetti tubing that Ford uses to route vacuum was brittle and broken in several places. I replaced them with rubber vacuum hose. It amazes me that Ford continues to use this crap!

[@InBloomLandscaping]

Mu 2016 "on the fly" system failed in the middle of the snow storm we got a couple days ago. THANK GOD for the ability to still manually lock them or I would have been hooped!

[@Go2Sleep911]

Chased ghosts in my vacuum system of the 09-6.4, finally found that there was a torn gasket inside the mini vacuum pump i replaced the pump and got things working again, never worked 100% of the time but closed to 90 figured the other 10% was just age of components especially the solenoid. Got a aftermarket one and it didn’t work well, got a motorcraft one and it closed the gap :-)

[@KratomSyndicate]

Can you save your axel shafts ( the zerk fitting knuckle area ) by not leaving in Manual fulltime? Just leave in auto and only use when needed? I had mine set in manual and forgot about it until recently.

[@PowerStrokeTechTalkwARod]

Yea....a no good

[@HerbMoore3]

On F-150, I believe applying vacuum disengages the axle. I prefer this, where application of vacuum engages the axle, where if you lose a vacuum line, you don't have an axle locking itself.

[@Butch33]

I have to guess that was somewhat the problem I had with my 2011 Expedition. The front differential would engage and disengage while driving down the street. It was diagnosed as a vacuum problem. Thank you God it was repaired and returned in one day.

[@gravytrainoutdoors]

On my 2007 my heater vent controls fluctuated between vents and defrost vents when the 4x4 was engaged when my hubs leaked vacuum. Not sure if that is the same on the new trucks but it certainly was an immediate telltale

[@andrewwindjack1252]

Me i guess I'm just old fashioned and would rather get out of my truck and lock in my hubs when I needed

[@turbotonye-4124]

I have a new ‘22 F-350 with the 6.7 I just ordered aftermarket hubs for it. Manual locking hubs or free none of this auto B.S. that can break. Ford has so many problems with these stupid vacuum hubs. Wish the would get rid of them altogether.

[@andrewmiller1761]

I have a 21 f250 with 25k miles. Just got new hubs and vacuum lines courtesy of ford.

[@albee253]

Excellent video. I just replaced front hub assembly. However I have a front growling noise. I jacked up the front and was able to manually lock the truck in 4x4. But what can cause this noise? Im thinking i didn't torque enough for a proper seal or a vaccum solenoid or vaccuum line. .... Thanks

[@rhett528]

Great video! My vacuum line broke between the bracket and the knuckle fitting. I need a replacement. Do you happen to know the part number? Having trouble locating it? The whole vacuum line would work as well. Thank you for your time!

[@PowerStrokeTechTalkwARod]

I do not. Call dealer with your vin

[@markking3531]

So do all the current gen trucks have grease zerts on the cv joints on the front end and do the drive shafts have grease zerts on them?

[@PowerStrokeTechTalkwARod]

Just front 4x4 axle shafts. 450 has 11 zerks

[@TylerHill-u1r]

I managed to break the fitting on the vacuum like that wrap around the coolant reservoir. Needless to say I have a new vacuum manifold ordered. Would you make a video on how to replace the manifold?

[@jayfromtexas6718]

I'm not a mechanic.... I have a 1999 f350 7.3 dually 4wd. Just finished brake rehab (rotors, pads, calipers, seals and brake hoses) and noticed the vacuum nozzle on the knuckle. Also noticed the vacuum line from behind the degas bottle. But, there's no vacuum line connecting the two. I've just locked the hubs manually. In a perfect world where everything is working, (seals, switches etc..) if I replace the vacuum lines to the knuckle, I should be in good shape? Thanks.

[@PowerStrokeTechTalkwARod]

Yes

[@MyHMMWVaddiction]

My 17, 6.7 has the old school handle and manual hubs.

[@bozerbrett7867]

When I wash my 2021 f250 I manually lock and unlock my hubs to keep things from seizing up. When I do this, I notice fuzzy soap bubbles percolating up through the ford emblem on the hub. Is this normal? It does it when I go from lock and then back to auto.

[@PowerStrokeTechTalkwARod]

It happens to me too!!!!!

[@katrinaelliott9625]

On the passengers side of my 2008 F250,.I.found the vacuum line broken off at a little white what looks like a Lil, "one way valve," where can I but that, to replace it amd what the valve Called? Thank you love your vids.

[@petetrufant5244]

I had no hub activation the other day and it was the small plastic line near the solenoid.the heat in the engine bay makes those line brittle and it was broken in half.

I have a 93 Ranger and an 03 F350. Both I ordered new with MANUAL hubs, manual transfer cases and manual transmissions. My dad bought a new 98 Ranger which had the PVH vacuum hubs. They NEVER worked since new. Sometimes it would be 3 wheel drive if at all. Total Junk. He still has it but currently not running. If I ever fix it up I’m installing manual hubs I’ll never buy a new truck again. Just rebuilt the 4.0 in my Ranger last fall. Hopefully it will last another 31 years. Luckily I live in MT where we don’t salt the roads and have low humidity.

[@Doc.Holiday]

Subscribed… great content!!! Does the vacuum system serve any other function on a 2011 f250 powerstroke? I replaced a cracked vacuum hose 5 years back. Not shifting on the fly into 4X4 was the symptom. It isn’t pulling a vacuum again and the same thing is going on. I suspect the hose has become brittle and cracked again? However, additionally, on start up I am getting an engine light code P1249 Waste Gate Performance. Might this also be a function of the vacuum system?

[@PowerStrokeTechTalkwARod]

Cld be but the EGR system uses vacuum to control the EGR bypass. So if it was still a vacuum issue like a pump id suspect you'd have more DTCs

[@fyrmedic22]

Have you ever had an issue with the auto lock not engaging in cold and snow weather? I was driving up the mountain for work in a white out and when I switched into 4 wheel drive I got a service wrench icon after a few seconds and the 4WD did not engage. I was sliding all over. I got out and manually locked the hubs and it worked perfect. After I got down from the mountain to town, I checked the 4WD in auto and it worked fine. I have been checking it daily since and it works fine. Is it possible the cold and snow had a part in it not working?

[@wheelinndealin]

I have always been curious how ford does their hubs and 4x4, coming from a dodge and precious jeeps all with solid front axles it was always “in 4x4” I’m pretty sure this is known as a live front axle and then the engagement is just done at the transfer case, very interesting though. How often do you see the actual hub engagement fail on truck that’s made in the last 10 years?
