I'll pin this post. Eventually the IWE or integrated wheel ends will wear out and need to be replaced because they will lose vacuum. You can replace the ends if you want. Or you can cap the vacuum line off permanently which causes the driveshafts to be locked in all the time. When doing that you will lose a little fuel economy because of the increased rolling resistance.
As good as anyone could make a how-to video. No life story, no extra nonsense, no load music - straight to the point, showed the part number, how you got the part, why the issue was happening, and how to replace the part. In 68 seconds. Awesome job!
@@asagaston hey thanks for watching. Trust me I get it. When I'm usually looking stuff up I'm already frustrated and want the answer now not 15 mins into a video of something that should have taken 1.
Grinding noise started on my way home today. Stumbled on this video and replaced the valve, fixed it immediately! Thank you for the helpful video! Life saver and wallet saver here. My first though was transmission so I’m relieved this worked!
2020 fx4. Worked like a charm. Even the dealership didn't know. They gave me a service bulletin on transmission pump whine even after watching my video showing the noise. Thank you so much for the help!
The solution for this is to eliminate that vacuum line and problem solved... You have to put a cap on each end, 1 cap on where that vacuum starts close to the valve cover and the other at the solenoid That's what Ford service is doing, and they are not replacing the IWE hubs unless they're really bad or you're paying for the job.. My warranty did not covered the IWE hubs but luckily they are replacing cam phasers and oil pan so that's a plus for being an extended warranty.👌🏽 This happened to me 3 weeks ago and bought the parts, the new revised vacuum with blue cap and solenoid, and the problems persisted.. TH-camr Ford boss uploaded a video about this issue, and the technician at Ford confirmed, and as soon as I eliminate vacuum hose and capped there were no more issues... Hope this helps👍🏽
This is the simplest part to replace. However it might not fix the actual issue. I replaced the check valve and still had the rattle. I’m convinced it’s the vacuum lines. But a Chevy dealer looked at my truck (it’s under warranty) and they said it’s something transfer case related. Pretty sure it’s a vacuum leak. What would the transfer case have to do with my actuators losing pressure and trying to lock the axle to the hub? The transfer case doesn’t do that
The IWE or integrated wheel ends wear out over time and need to be replaced when they start losing vacuum. If you cap off the vacuum line that goes to the wheel ends you can engage the driveshafts fully all the time and eliminate the need for the IWE. The only thing they do is decrease rolling resistance to give you better fuel economy. It's a negligible savings.
my 2020 is starting to make a noise on the drivers side when I put it into drive. I thought it was the auto door lock mechanism but I can operate those individually and it does not make the noise. Starting to wonder if this is my issue. Stealer wants $250 to take my door apart and diagnose it? I will try to record the noise and post it in a few.
I'm about to give it a go! I was getting scared my tranny was starting to slip or something but it makes sense with it being a valve because for me it only happens when I'm accelerating which would cause more of a vacuum.
Thanks for the info. When your grinding noise occurred, did the noise ever end with a thump? My grinding noise starts and seems to get louder (faster) and then ends with with a thump. Thanks
Thanks a lot. I really appreciate it. Have you encountered pillows of smoke coming out of the tailpipe, white smoke, especially but not limited to, cold start first thing in the morning? I have 200 K on my 16 Eco 2.7.
I have replaced borne front IWES and wheel bearings and the check valve. It’s still intermittent and only happens in 2WD but not 4WD. I’ve taken it to the dealer over 7 times and they keep charging me money to fix different things that aren’t fixing it
Funny thing about this. I had this problem for a few days and took it into a tire shop and they said their was something wrong with the front differential. I popped it from 2H to 4A and back to 2H and drove it all the way home without the sound the whole time.
I’m having a similar issue. 2013 raptor, grinding type noise coming from driver side front end. Only make the noise while on the gas, and only while in 2wd. Noise immediately disappears when i get off the gas or am in 4wd. Any thoughts?
I have a rattling/grinding noise that just started happening while pulling my camper. It was happening in 4th and 5th gear cruising with fairly light to medium throttle and stopped as soon as I let off. The noise would sound worse if I let it go on without reducing throttle. Is that at all similar to the conditions you experienced?
This is exactly what I was experiencing in my 19. Almost like you could feather the sound with the throttle. I’m going to try this fix to see if it works.
SAME HEREE. 2019 f-150 v8 5.0 and makes noise worse like this when pulling my camper. but can have a rattle sound while changing gears without towing as well but not as bad as towing. did this work for you?
So, I just made this repair, when I went to do it, I realized it was already capped off. Would you by chance know the name or part number of the vacuum line on the other end of the check valve that drops down? I want to replace that and see if itll fix the noise though i'm sure IWE's are already worn out.
@@mitcholson9795 the actual IWE itself in the hub is more than likely bad. You can cap that line you just replaced off it will cause the IWE to lock in all the time. You can either leave it like that if it fixes the problem or you can use it as a diagnosis to see what side the noise is coming from.
@@mitcholson9795 i personally just have my lines capped off permanently now. The front shafts now spin with the wheels all the time now. It made a very small difference in fuel economy but eventually that IWE is going to fail again.
I ended up taking mine into two different shops after I tried both parts. Mine ended up being the left hub assembly. I kind of figured I'd wear mine out a bit faster than others. I've also got a 6 inch lift and 35" tires on my 2018 F-150. At least I have the other parts on hand when they do go bad 🙂 @@usupr23
No one figured it out? Mine sounds like pads and or rotors, but it had new pads rotors and bearings and I took it back to the shop they said it's not any of that..and they don't know Makes grinding randomly and when turning left more..
@@MotorCityMetalArt Thanks, if I unplug the IWE solenoid and the noise stops does that pretty much indicate it is an IWE issue and not a transmission issue?
Do you have a video of how it sounds mine is a type of grinding while driving over 10mph on the acceleration or off even just coasting anything helps thanks
Mine has this same noise. It’s been at the dealer for a month. They claim it’s a switch inside the transfer case. Absolutely no way. The transfer case has nothing to do with the hubs locking to the axle. It is without a doubt a vacuum leak or solenoid problem. But l’ll leave it to them to figure iut.
Easy way to check is switch it into 4x4 when it's making the noise of it goes away you have an issue with the IWE somewhere. Could be that check valve could be the IWE itself
Have the same problem with my dads truck on a 2018 ford changed new rotors new front axles and it kept making the same noise even on 4wd idk what it is anymore
I've heard some people describe it that way but didn't sound like that to me. More of a grinding noise. Good way to check if it has anything to with your IWE is to put the truck into 4x4 if it immediately goes away it's either the check valve or the IWE itself is wore out and it's losing vaccum.
I have a video in which this issue is demonstrated in a 2017 ford 150 Lariat 4x4. I would like to make it available to you, in case you want to revise this one to show the symptoms. I think it would add value to your already valuable video. Please let me know, if interested.

Hi. Are there two of these hoses to replace or just the 1. I bought a used 2019 f-150, was getting my oil changed and the guy said these vacuume 4wd hoses on your hubs are unplugged.

No. That sounds like cam phasers. If you have a 3.5 engine cam phasers are a common issue
