The Hum, Thrum or Throb

I own a 2016 mid roof 350 Transit Wagon, 3.7L engine 3.73 limited
slip rear axle, XLT trim long 184 wheelbase. Purchased in mid July
after about 100 or 200 Kms or 55 or 125 miles, I noticed that there
was a low level noise, that throbbed when I was around 50 MPH or
80 KMS, most noticable at 75Kms. , especially when I am slowing down
and the engine is at 1500 RPM. so far the Ford dealership has replaced
steady bearings, universal joints, and the drive shaft, as well as
put new gears in the rear end. The wheels have been rotated, and
checked for defects, and still this annoying noise exists.
The interior of this 50 thousand dollar vehicle is also pretty cheap.
When I owned a mini van, the seats folded ahead and were
versatile, the transit is basically functional. There is no lock on
the glove compartment, and the windows of tinted glass, let in the
heat from the sun. If I were to get another van I sould get the privacy
glass, and the SYNC 3 system just to have the larger backup camera
display. I am happy with the engine even though it is not as peppy as the
3.5L eco boast, but it tows a trailer okay, and does the 120 to 130KPH
or 80MPH in the USA highways okay.
I just wished I had a van without the throb that I hear every day.

Change tires and see it the noise stops. Another thing to check is tire air pressure. Most come off the assembly line with 75 PSI and that makes for a hard bumpy ride.

the transit was built to be a work van first, passenger comfort usually takes second place. ford often slightly over inflates the tires, try letting 10 or 15 psi out of them, it will soften the ride and it might quiet it down, but this is just a guess? use the search box to find more info and read a little about it here: Tire pressure

Ditto on Michael's input. The Transit is designed as a light duty commercial vehicle, a delivery van or plumber's truck, not a passenger vehicle. The same concept is hard to get across with new Sprinter owners, who think that because there is a Mercedes symbol on the van that it is somehow a luxury car (lol). Adding rear seats just makes these commercial vehicles a shuttle van, not a limo.

Specifically to the comment, there is often a certain resonance rpm that causes things to vibrate. My 03 Sprinter is loud at 62-63mph, but not 60 or 65. Understanding a little about music instruments and sympathetic resonance helps explain this phenomenon. Length of engine mounts, composition of materials in the drivetrain, etc. It's nothing harmful, just annoying.

To the previous posts I only have two annoying noises in my wagon. The whistling noise that occurs depending which direction the wind is blowing and how stiff. When backing up a noise others have described better than I.

If all that has been replaced then the wheels and tires are the only other logical issue.

HARMONICS of the motor?

ME TOO!

Hum, (relative) silence, hum, silence, hum, silence, hum, silence, hum...while coasting.

(I'm using the word "hum," for lack of a more descriptive word.)

I have had this problem too since picking up the van new. It does seem to have gotten a little quieter, hardly noticeable now but still there.

Further to this 2015 350 Transit Van, It is an XLT model, and I thought it would have the standard Ford quality
like the rest of the 4 Ford pickups and 2 Econoline Vans that I have owned. I was very happy with all of my previous
vehicles, and when I got into this new large 12 passenger van, I was disappointed with the seats not folding ahead
to load things like plywood , drywall, lumber, as I did with my other vans. I am told that the seats are a European
idea, hence, they do not recline very much as well.I also did not see many windowed van in my city, so I did not know that
the tinted glass would not be good enough to keep the Summer sunshine heat from roasting the interior every day.
Where I live, it is mostly the fleet sales departments and such that sell these vans, so as a single owner, they were not
that interested in me, as these salesmen like to sell 10 or more at a time. Great if I was an owner of say AVIS, or
Hertz or such rental car companies, I did not get my van as a 15 passenger machine as the seats would have been right
back to within a foot of the rear doors, so not room for suitcases or stuff, if the van is full of people.
I hope to maybe get a different van with the 3.5 Eco boost engine, as it has a different transmission and rear
axle with that model, and maybe that would be the way of not having the Throbbing sound every day that I go
out for a drive.

Sorry you're disappointed in your purchase. Most of what you mentioned @Stargeezer*8998 do not sound like quality issues and are likely fixable. Make a call to Ford corporate state your grievance of the hum, etc. See where that gets you. Personally I hardly have the radio low enough or have all the factors lineup that I hear this noise. Good luck.

I could be wrong, but I don't think that's true.
