The best video I've found so far on troubleshooting the problem. Every three weeks I drive to or from work 10 hours, I've started getting this grinding noise about 6-8 hours I can switch to 4wd and back to 2wd and it goes away, happens about 4-5 times over 30 minutes. Ford dealership stated there were no codes, so I need to dig deeper, an intermittent problem.

Completed a right-side IWE replacement today. Disassembling revealed that the IWE had *split in two*, with the spline gear stuck on the hub's spline and barely engaged on the CV side spline. Explains why the grinding was on right-hand turns - the weight of the CV would cause it to disengage from the stuck spline gear. Both the CV and hub splines where in perfect shape, so I avoided a far more expensive repair. The replacement tested fine during assembly and when everything was back together, let's hope it lasts longer than its predecessor.

Just had this problem on my buddy's truck, just on the driver's side. Turned out all the plastic vacuum lines were crap, they fell apart in my hands, replaced them with new rubber vacuum hose, that's what I had, fixed the problem. So people check all the vacuum lines, especially where they connect to the rubber elbows, could be your problem and save you a ton of money.

The solenoid can be partially blocked as well. I just replaced the IWE's on my truck and the passenger side still would not disengage until after the engine is run for a minute or so. You could also hear the IWE's slap over small bumps and clunk on hard slow turns indicating very weak vacuum. Replacing the solenoid even though it was still technically functioning electrically, solved this. My best guess is the solenoids range of motion degrades over time to the point where it is never open enough to get full vacuum after a certain point. It's probably best practice to replace the solenoid at least once every 2 years by my experience. By year three they are definitely done. Will save you from having to replace the much more expensive IWE's which I had to do as they were both destroyed on my truck and it is only a little over 5 years old.

If it hasn't already been mentioned, Ford just gave up on IWE on the 2015+ F150's. The truck's all still come equipped with the same setup as above, but they released a TSB instructing it to be locked out with the hubs always engaged. Tsb 22-2219. The vacuum is capped at the solenoid.

Mine was fairly easy to diagnose because it was a split hose. The zip tie clip at the very end that pushes into the knuckle ate a hole into the line.

Very helpful, Sir!! Thank you for making this video . This has helped me diagnose my problem. I had no idea that vacuum was applied to release the hub to engage the front axels. I knew my old Fords used vacuum to engage the front axels. I thought it was a bad hub. Now, I am almost certain it is IWE or vacuum problem. My truck is a 2020 and still under warranty. At least now I can tell my Ford tech where to start looking. Thank you!!

Thanks for the video. My 4x4 wouldn't engage. Checked solenoid and it was full of fine sand, so i replaced solenoid and checked the 2 valves on my 2007 f150. Still did not work and no error code. When put into 4x4, the vacuum from top port would not stop. So i replaced the tranfer case switch and that did the trick. The tranfer case switch must need to be working to groung out solenoid for (it) to work. 🤷‍♂️ Thanks again for the vid!

I'm having that Grinding noise on my 2014 f150. I have tested vacuum at the wheel ends and there's 23 lb. The solenoid is switching on and off. I tested both iwes and they function correctly and hold vacuum at 15 lb without leaking. The truck only makes the grinding noise when it is cool in the morning below 55°. The noise goes away when switched into 4wd. Once the truck is driven and warmed up. It does not make the noise again. I have ordered a new check valve and waiting for it to arrive from Ford. Update: even though the check valve was bad it did not fix the problem. I ended up replacing both iwe's. Now it's nice and quiet like a new truck.

I have an '18 F150 with the intermittent grinding noise coming from the right side. Started about 2 years ago. Have been to the Ford dealer twice and they have not been able to figure this out. Last time I brought it in they told me it was something that was frequent in F150's and there was no fix. It would change with the weather. Dude, I kid you not. That is exactly what they said! Like my Ford has arthritis or something. I am convinced it has to be the IWE since nothing else seems wrong and everyone on youtube that describes the problem sounds the same as mine. Time to get my hands dirty and solve something the manufacturer themselves could not figure out. Frustrating thing is it started while truck was under warranty, now I might have to pay for parts out of pocket. It's interesting as it seems like if I put it in 4H for a few miles it'll stop for a day and then comes back. Hmm, maybe a weak solenoid?
@737mechanic

The best thing you can do is buy a handheld vacuum pump. amzn.to/3peNtOk and unplug the iwe's and pull a vacuum and make sure they hold solid, if they do use the vacuum pump gauge to make sure you are getting good vacuum down to the iwe's.

Mine would grind and only when the truck was moving, I thought for sure it was the bearing hub. One morning I started up the truck and the grinding noise started. The first time the sound was made while at a stop, turned out to be my water pump. The grinding only happened while moving previously. I could barely turn the impeller on the old pump. And the funny thing was, I started up the truck so that I could position it to jack it up and inspect the hub bearing.

If you get a vacuum gauge or a mityvac you will know for sure how much vacuum you have at the different areas of the system.

It could be the IWE, check valve, solenoid, or vacuum leak.

My rear right is trying to engage when turning right or backing up. By releasing the vacuum lines and putting them back on it stopped doing it at least for my trip home. Trying to figure out what's the issue. I had vacuum can't find a hole yet. Hoping it's cheap and easy not a hub

My 2020 does it intermittently. How do I determine the culprit since it’s intermittent?
@737mechanic
@737mechanic 9 месяцев назад
First thing is to check and make sure the vacuum system is tight, do that with a hand held vacuum pump. What you will probably find is a small leak.

@@737mechanic thanks. I’ll give it a shot. Also, mine only tends to do it when slowing down to make a turn or stop. I never notice it at speed or after initial acceleration. Does that indicate anything specific to you?

If I replaced the IWE about 8 months ago do they go bad? I hear a grinding noise now. Could it be the solenoid?

Im having issues with vacuum. Driver side vacuum is strong and passenger side is weak. Is that normal? I did pull a vacuum on the hoses and the vacuum did hold. Actuators are good too. Oh one other thing, i have crazy vibration on passenger side when going 50mph. All new suspension passenger cv axle new and my 4x4 stopped working a few months ago.

If it is a EcoBoost engine, make sure the mechanical vacuum pump is pulling at least 16inHg at the IWE's

I’m getting a grinding/rumble strip feeling when I engage 4wd. When I switch it back to 2wd it goes away and truck feels like normal . Could I possibly have a bad iwe.
@737mechanic
@737mechanic 2 года назад
Yup, but first check everything else because the solenoid, vacuum hoses, or check valve can also be bad.

@@737mechanic thanks I checked and vacuum is good to both iwe and no grinding when in 2wd and in 4wd there is no vacuum which leads me to believe an iwe is broken or not fully engaging.

Having this issue on a 2015 F-150 I bought a week ago. It is a blue certified used vehicle. This grinding noise happened intermittently on day 3 of ownership. I took it back to the dealership (Apple Ford, Columbia Maryland) and they had it all day. Two people test drove it and never heard or felt the issue. So they did nothing. I showed them a video recording of it happening and they said they have to witness it themselves before they will replace it. This is clearly the issue!! I have never been so frustrated in my life with a vehicle I just got. I can't afford to keep leaving it there for them to test drive it and it never happening for them. I plan to call Ford directly on Monday. Anyone else have any suggestions on how to get them to fix it? I shouldn't have to pay out of pocket to fix a certified vehicle I just bought!!

Help? I have 2012 f50 4x4 and I’m having a very similar problem. I have been trying to determine if my issue is the same using what I understand to be your diagnostics. Who, when the truck is shut off both front wheels are in engaged to the axles. When I start the truck both front wheels disengage and spin freely. What am I missing here??

@737mechanic 2 года назад
You are probably losing vacuum while you are driving. Check the check valve and hoses and make sure everything is good.
