Vibration-Huming noise

Hello all, I have a 3.5 EB, HR - my van has a vibration and humming noise that we can not seem to locate. The vibration seems constant and can be felt even at idle when in gear, the noise appears most evident at speeds of 65-95 km, and frequency changes with speed We have balanced tires, tried a new set of tires, nothing changed. I drove another Transit on dealers lot it actually did the same thing. Does anyone else have this issue? The noise is more annoying then the vibration it really sounds like a bad belt in tire but it is not as we tested for that. Any feedback would be appreciated.

I can relate. Back in 2005 I was given a loaner Sprinter with the factory, solid bare metal partition. The engine noise bouncing around in the cab was maddening. There are untold thousands of those rigs on the road and I've never seen a single complaint anywhere. Maybe it was just me.

Mine has similar characteristics. The vibration is felt in the steering wheel at 95-100 km.
The noise I would characterize as a "thrum". It reminds me of driving with a rear window open, only Milder.

I have had tires replaced and lots of front end work, but the vibration and veering left continued. My thread "new van didn't get far" refers.

Oh it is good to hear that some of you have the same problem. I really thought that I am the only person on this planet who has it. this awful noise is driving me nuts! It feels like there is a big subwoofer in the back which plays this super low frequency tone (about 10-20Hz). It definitely does not come from the tires. The tone starts exactly at 55km/h and ends approximately at 80km/h. The steering wheel is also vibrating noticeable up to 100km/h.

Ford is now trying to find out where this comes from. I think they ordered a new dual mass flywheel. I really hope that this is the solution..

Interesting, the sound is very annoying.

Would appreciate if you keep us posted on this, especially if the flywheel fix is successful.

use a gopro camera and move it around to different locations in the van-- to hear noise -
using a LAV mic plugged into cam will make things easier because its small
and easily place - use magnets - -clothes pins- tape-etc to hold mic in place-

wrap acoustic foam on mic to stop wind noise -or second best wrap mic with some tape -

there is a Tiny sony Lav mic sold on ebay for around $8 or so - its T shaped -
it will work OK for this- then plug it into 3.5mm cable and you could use ANY camera/ phone etc

Thank you all, will be interesting to see if flywheel fixes this, I would suspect if enough issues arise a service bulletin should be issued. My vibration appears to be present at all speeds, the noise is exactly like wind noise., jonsobi I have read your thread. I am thinking that issue could be an un- balance in driveshaft?

For a second there, I was going to suggest it's 3.5 EB specific, as my 3.2 doesn't vibrate, but then lotuseater chimed in. So there goes that theory.

Reminds me of the infamous Sprinter Rumble Strip Noise, or RSN, as it became known.

It occurs to me that it may be a harmonic vibration... My Sprinter had one at about 65-70 mph, combined with the RSN. Learned to simply ignore it. Then I put in a boomin' sound system and all kinds of noises got ignored.

RIP Lemmy. Of all the things I've lost, I miss my mind the most.

Thank you for the video that is what I suspected unbalance in driveshaft area... Will go back to dealer, problem is they have little experience with Transit thus far
