Intermittment Whistle Noise

[eddiemoney]

Got one heck of an annoyance that can't be pinpointed - looking for help.....

I get a whistle noise at speed; sounds like its coming from the front, underneath the vehicle...maybe more on the passenger side. It has been doing it since new, but is becoming more frequent - almost 40K miles now, 2010 EL 4x4.

Its not a howl like a wheel bearing, its higher pitched compared to what I have heard from bearings.

It shows itself over 55mph; comes and goes. Most prominent at light acceleration, under heavy acceleration it goes away. Once it 'starts' it will typically continue through a stop without acceleration ( have found because i have pulled off to try and find it immediately off the interstate). Unfortunately as soon as I take back off from the stop it goes away.

Dealer looked around when they replaced the passenger axle seal and didn't see anything - when I asked for specifics they didn't give me crap so I don't think they even bothered to try and look...very frustrating

Throwing it out there, looking for creative ideas

Hi eddiemoney,

I want to get your regional customer service manager involved so they can assist. Send me a PM with your VIN, dealer, mileage, daytime phone number, and full name; I'll get your case escalated.

Thanks!

Sounds like a vacuum leak. Are the hubs vacuum controlled on the newer models?

Shot in the dark.. (investment... 30 minutes of your time)

Try removing the Idle air Control Value.. Clean it... Make sure it is absolutely dry...
Reinstall, then remove battery to reset the computer...

Its very odd....seems like its louder than the vacuum lines...its a notable whistle/high pitched howl that I can hear well above HVAC and radio (unless the radio is turned way up) -> Crystal, looking forward to seeing what you can do to make my dealer investigate rather than just "not reproduce it"...it's super annoying; took a 30 mile trip this weekend, happened three times on the way down, none on the way back...seems random to me

I'll report back on this thread on what Crystal from Ford can help arrange ! Glad to know there is someone that cares!

I recently purchased a 2016 Expedition. I have the same exact situation occurring. Has there been any resolve to this issue?

Mine is an older 08 with 115 on the clock. Mine as a very high pitch squeal that goes away when I put it in 4A.
When it does make the sound it’s at certain speeds. 10mph through 40mph. Above that or below it the sound stops.
The mph variable not always at those set speeds.
But it stops every time I set it in 4A.

Maybe something to look into.

In that case it sounds like something vacuum related... In 4A your solenoid vents vacuum allowing your hubs to engage. Wonder what component it is in the vacuum system that causes the whistle.

Jennifer has a 2016. It’s probably her turbos
