Should be a courtesy upgrade with an oil change or service. Ford can afford it. If they would use their heads they could turn a courtesy into a profit and win a loyal customer.

If ANY manufacturer did this as courtesy I would own and rep that brand until I die. Unfortunately it don’t make money.

[@userwhocantfindaname]

as long as you don't buy the new generation/design when it first comes out then you'll usually get a heads up for these kinds of problems it won't have to be a "courtesy" repair because if you buy the truck then you either didn't research or you knew it was gonna be a problem and picked it anyway

This video started my journey to fixing my 2015 F150. I had an intermittent metal on metal scratch/grinding noise when accelerating. I replaced my check valve with an aftermarket part, replaced my solenoid, both wheel bearings, both IWEs and couldn’t get rid of the noise. I then tried unplugging my check valve to force it into 4x4 and the sound went away. So after watching dozens of other videos I came back to this video and decided to try to buy the Ford check valve. Problem seems to be fixed. Thank you for this video I’ll be watching more of your videos for sure.

[@michaelrobinson5347]

Can you elaborate on grinding noise? I'm heading a scraping sound coming from my 01 but it sounds like it's coming from under my vehicle, not the engine bay. Hard to tell for sure though. Wheels don't make noise when I jack it up and spin them

[@dirtsfunner]

Damnit! I just bought the black one the day before yesterday! I took it on the freeway, got up to speed and BAM! Its back!

[@garrettmckenzie9178]

Just change your 4wd actuators to the vacuum delete ones and you don’t have to worry about any of that vacuum crap

[@alkalk8938]

And after that you can replace the IWE's and wheel bearing hubs because those splines will be mushroomed from grinding. Occasionally one side will get hung up while the other disengaged, this causes one drive axle to spin with the tire and the other side to spin backwards very fast. I discovered that very expensive problem about 5K miles after warranty.

[@benztech2262]

And this check valve may have prevented premature IWE wear.

[@Blake-wy6ov]

I have a 2020 f150 with the updated blue check valve and i recently started experiencing the intermittent grinding. Any suggestions to fixing this?

[@FlyingWrenches13]

Either you have a very small vacuum leak somewhere or a bad IWE

[@mrcrazycrazy1000]

What I see basically daily. Which I’m sure has a lot to do being in Canada but basically the axle face will get a ring a of rust where it sit in the IWE along a seal. Pop the IWE out. Take a die grinder with a cookie. Clean the axle face and put grease on it. IWE grinding noises now go away

[@FluffyMexicanik]

Quick question bro...props for killing it on the videos...i just came across the channel by looking for other techs at dealers on youtube which leads up to the question, have you had any back lash from ford?? I have and so has my dealer, recently recieved back lash from the manufacture for me making videos just as i was putting up abour 300k views a day

[@mannys9130]

I have always wondered this as well about you guys who do this. Criticizing and bad mouthing the company that you work for as well as their products while on the clock and wearing the uniform of your workplace seems to be begging for a collosal wrist slap that could even include termination. I would think that once Ford or the dealership became aware that an employee was doing this, they'd demand takedown of the videos at the risk of immediate termination and a slander lawsuit in the case of noncompliance (it would be more of a SLAP suit because Mayson clearly isn't lying about any of this stuff nor spreading unverified malicious rumors intended only to harm the company). I think it would be much safer to make this style of videos without the uniform on, without the name tag, without the dealer's name patch, and without showing your face. Even if you do show your face, it would be much more difficult for the employer to slam you for it because it would be on your own time. A lawyer could make a case for freedom of speech, but that still... If your state is a "right to work" state like mine is (Arizona), you can be fired for any non-protected reason and at any time without warning. Boss doesn't like you for some odd reason? Maybe he dislikes the sound of your voice? Terminated, based on performance concerns and the few tardiness incidents that he's been keeping a very detailed record of for a few weeks prior. That's it. Done. No recourse on your part unless you've got some seriously compelling proof that you were illegally discriminated against based on protected factors. I'm gay, and it's a very real, scary danger for people like me because a homophobic boss can toss us out at any time like that. They won't outright say it's because I like guys, but they probably could and still be within their practical abilities to fire me. At every job I've worked at, I've established a rapport with my coworkers and bosses and demonstrated that I'm a valuable member of the team BEFORE even thinking of coming out. That way if the boss is homophobic and will dislike me, it'll be hard to prove that I'm a bad employee and my termination would cause bad morale and discontentment with all the other coworkers. Anyway...I asked Project Farm if he had ever gotten legal threats, C&D demand letters, copyright claims, or even physical harm threats as a result of years of exposing multiple brands and products as pure shit. He said no, which absolutely blew my mind. 😸🤯 I wish you luck on your upcoming battle, Fluffy. I bet you're sad and your bubble's been popped, but you can always switch gears and make more anonymous videos and just private your previous ones. Your current subs will still watch new releases and should understand your predicament.

[@FluffyMexicanik]

@@mannys9130 i get what your sayying, i finally got noticed due to a video that struts were put on backwards by somebody else, i caught it and fixed it and well another tech out of state that works for the same brand saw it, show his boss, boss showed area manager...that worked its way up to some decision makers for the brand then trickled down the ladder to my boss and mannnn was i fearing for my job...still kind of am but i never slandered the company or the product i just basically showed what i do with some comedy...and this is all still fresh like this past friday fresh...but now my boss is thinking all my other videos were actually good and i had no ill will it was just that 1 video that was seen as "wrong" so now theyre in the talks of letting me do my thing now knowing what i cant do or show...

@@FluffyMexicanik this one summed it up for me. I honestly beg to be fired everyday because I know the industry and I know that not many people can do what I can do as a technician. My only rule about making videos like this is that I don’t lie. (Besides the comedy lines haha) I have never had any backlash from ford or my dealer. I have the pleasure of working for a very good dealer with a bunch of very good and down to earth people. But to answer your question, if it came to the point that the dealer or ford told me to stop these videos or I would be terminated…. I would simply reply: my box has wheels on it for a reason.

I had a clicking grinding noise occasionally because this check valve failed and the hub tried to engage. I swapped it out and it fixed it.

It sounds like the lug bolts are hitting up against the holes in the hub that they are coming through. Should there be that much play? Ty

[@Krankie_V]

And if you don't fix it quickly, you'll have to buy 2 new wheel bearings and 2 new actuators, plus the check valve once they strip out. If you're hearing that noise as you drive, unplug the vacuum solenoid until you can get the check valve fixed. That will keep the 4wd actuators fully engaged all the time.

[@jakegraham9454]

That sucks cuz i just replaced both wheel bearings trying to find the problem and come to find out it was probably this the whole time

the problem is it came from mexico 🙄 and i myself im mexican and is no joke, i had the "plant" 20 minutes away and we had even to wait almost a month at the dealership i used to do side jobs for stupid ford parts

[@AmericanRustWorker3369]

$250 for that easy fix😳?! I’m glad I’m a mechanic that doesn’t own a ford

[@mikefoley7561]

I helped develop that fix

2006 f150 also the same or where can I find it?

[@trevorjbailey9726]

I just pulled the lines and capped it. Allowing the iwe to be engaged 24/7.

[@joshnc101]

I did that, and installed RCW IWE eliminator gears on my 2017 f-150 after going through two sets of OEM actuators in 4 months. They should’ve designed them to be electronic actuated from the very beginning rather than vacuum. I recently discovered the new trucks Lariat and up trim levels completely did away with the IWE, but XLT and below still has them.

[@ironmike742]

There's a new TSB to disconnect the vacuum all together and cap it off. IWE stays engaged all the time and reprogram the Transfer Case Module

[@georged1085]

Curious what he thinks about this?

[@ironmike742]

@@georged1085 nothing to be curious about. I work for Ford. This is Ford's fix for the issue.

[@georged1085]

@@ironmike742 yeah but isn’t there more wear and drag with the axles constantly spinning? I was gonna prolly end up replacing iwes or hubs if I can’t find a vacuum leak but this fix sounds cheaper and easier
