Driveshaft Drone Noise Survey

Do you experience the highway-speed hum, vibration or droning noise in your Transit?

I just went through the vibration and humming noise thread collecting bits of data looking for a pattern. I have found just enough to see hints of something, but no smoking guns yet, I need more data. If you have the problem or think you do, it would be super helpful if I had:

- Model Year
- Wheelbase
- Engine
- Rear drive ratio
- Speed range where you hear the noise

@BrianK*1954 , @Stargeezer*8998 , @belloinsella , @jhal , and @lolwisper4321 , I was able to gather yours from postings in the other thread. Thanks!

Awesome, MikeQBF!!

I think all of us who either lease or own this vehicle knows in our gut something is inherently wrong with the driveshaft/drivetrain assembly. I think Ford knows it and I hope that we collectively as a group can raise our voices and say we are not going to let this matter fade out.

It was a royal pain in the a$$ when I had to drop off the 1st new van to San Tan Ford the week before Christmas and be told that the new driveshaft wouldn't be delivered until after the New Year. The parts didn't show up until yesterday, January 11th, and after the new parts were installed, and the vehicle road tested, that San Tan Ford discovered the humming noise remained.

We shall see what happens next....

For me, the humming/droning noise commenced @ 75 MPH and became much louder @ 80 MPH. Any speed below 75 MPH or above 80 MPH causes the humming/droning to stop.

MikeQBF: where can I find the rear-axle ratio?

Just found this.....

https://www.carcomplaints.com/news/2...-lawsuit.shtml

The lawsuit alleges when Ford Transit owners complain to the automaker about the driveshaft problems, Ford allegedly denies knowledge of the problems and makes owners pay for repairs. However, the plaintiff says Ford has known about the driveshaft flexible coupling problem since 2014 and finally ordered a recall in June 2017.

Ours is a 2015 148" T350 wagon with 3.7 engine, regular 3.7 rear end.

It now has 245/75 16 tires and the Giubo was replaced with no change in the drone.

The drone is noticeable and somewhat cyclical yet not terrible at 45-55 mph mostly when letting off the gas and coasting, but no vibration or anything. It seems more acoustic than anything.

I am also still curious about the pinion noise damper discussed in one of these threads. I wanted to experiment with one yet haven't had the motivation & time to yet: There is a pre-recall and post-recall version.

I am on the highway constantly and don't really have any. It is possible, however, that I've just gotten used to it. I have a bit of tire noise since I added BFG KO2's which could be drowning it out.

I responded to this because I do have vibration, just different than the original question asked. I have vibration just off the line in first and especially second gear. It goes away as I shift through and get faster. I thought this was just needing a new flex disk and I could swear it went away for a few days after that was replaced but it's back already. It's a pretty good shimmy especially in second. The harder I accelerate the LESS it's noticeable but I don't find comfort in this. I generally drive my cars pretty conservatively.

I ordered my Transit (MR T250 148 3.5 3.73LS rear) in May, delivered the end of August with the permanent driveshaft fix. I have the drone, the clunk, the vibration, the resonance, etc. Something in the total design of the van leads to all of the mentioned annoyances. Different speeds result in different annoyances on a daily basis. As long as it will remain reliable, I can live with the nature of the beast, but if problems result from these issues, I sense another purchase after the warranty period expires.
