Mine makes the same hum, it reminds me of my lifted truck with big knobby tires. So I automatically thought tires. To those with new replacments, are you still putting Hankook tires on. It could be the tread design. I was hoping once they get worn down a little the noise would go away.

Hello update on my Van and its vibration and humming noise - the Van has been to Ford 5 times and another mechanic shop 3 times in an effort of trying to find the vibration and humming noise. Costing a lot of time.

At Ford they have told me it is the tires - we replaced the tires, road forced balanced them all wth no results, then they said it is the power steering pump - they replaced the pump still no better, now they are saying it is due to my conversion and the roof rack and roof vent (a Ford roof rack) - I argue that most vans have roof racks and vents and they would have a lot of customers lined up if that was the issue, then they tried to tell me that this maybe a 'normal' condition for the van - again I use same argument - they would have a lot of customers in their shops if it is 'normal' to have a van with a vibration and humming noise, we would all be driving Sprinters.

At the other shop we have put the van on the hoist and driven it in the air - you can actually hear a loud noise at the end of the transmission where the driveshaft connects - and you can feel vibration in that area - I explained this to Ford - they state that this is normal for these vans. I am convinced that the issue is somehow drivetrain related - Ford does not think so.

So now we are waiting for a Ford Engineering Rep to come and look at this - tomorrow the van is going to Ford again to have a vibration tester installed (for the 3rd time). It really seems to be like we are getting nowhere, especially as Ford just follows their diagnosis protocol and the tech and shop probably can not bill Ford for diagnosis?.

To re-cap the problem(s) - there is a THUM,THUM,THUM or HUMMING noise (like driving on unbalanced tires) in the van that you can start to notice at a speed of about 30km (20 miles), it really becomes loud at a speed of about 80 km to 105 km (50 - 65 miles). It is most noticeable when van is under load, i.e accelerating or going up a hill, less noticeable coming down a hill, the noise also seems to reduce when in Neutral but does not go away.

The Vibration seems to start at speeds of about 30 km (20 Miles) to about 105 km (65 miles) - the sweet spot where it seems worse is at about 60Km or 40 miles, at this point you can see the steering wheel vibrate.

I hope that others that have this issue speak up and let us know what they have done so far and what their plan of action is - to me it is NOT normal to have a $55k Van have vibrations and humming noises. Ford needs to step up and get it fixed - does anyone know what the next step could be?

I have had a roof rack make a loud hum in the past, but it's a very steady note and dependent on airspeed, not engine RPM. Had a big pipe rack on an F150 at one place I worked, they had one of the crossbars directly over the cab and anything over 55 MPH induced a mind-numbing drone inside the cab. I finally took that crossbar off and the noise was gone.

But, again, that sound wouldn't change depending on engine load.

I'm starting to wonder what good a warranty is, when all they seem to do is say "that's normal" for every problem they are confronted with... :/

The thrum noise in question has been one of many issues I have had to deal with on my 2016 Transit. The noise has been constant since new, and has changed little once my conversion was completed.

Having had a very bad experience watching a dealer flounder away at my many other problems, I would be reluctant to take my van in for this elusive problem. The Transit experience has been a big disappointment for me. I had no idea how difficult it could be to get competent service expertise.

Having been a Ford fan for years, its hard to own up to this.

I have already considered getting rid of the van and going to a Sprinter - BUT it would cost a fortune, the hit I would take on this van would just be too much, somehow the issue needs to get resolved.

I find myself in a similar position, although I would not consider the Sprinter a better risk.

My issue is less with the Transit and more with Ford's disinterest in resolving long festering problems. They have made it abundantly clear that they simply do not care.

The Ford CS rep for Arizona told me that my Transit problems did not qualify for action under State Lemon Laws. One of the criteria, IIRC, was loss of use for 30 consecutive days. That is a pretty high bar to reach.

I await my return to Canada to see what Ford.ca has to say. I am not confident of any positive outcome.

Well all of that is not sounding good. I just installed a rear sway bar, it adds two more points of contact to the frame. So I thought if the noise was coming from there it would be reduced after install but no luck. Still as present as ever. With that eliminated I am thinking it too is the transmission. What ever gear it runs in at that speed, 45 to 55mph.

The Transit has the same transmission as in the F150s, doesn't it? I don't see anyone complaining about this sort of noise on their forums.

So that leaves me wondering about the giubo - which the F150 does NOT have... Perhaps this is why they're cracking so quickly? Or maybe they're just low-quality, crack a bit (or separate internally?) then start vibrating - and that's what makes the sound?
