2022 Driveline Vibration 37-42MPH

Hello all, I also have exact the same problem with my Explorer PHEV ST line . I also experience vibrations when driving between 30 – 65 mph. The intensity of the vibrations are not always the same.

I will tell you my experiences, maybe it can help someone. English is not my native language, excuse me for mistakes.

Trying to solve the problem the first thing I did was changing the wheels, but that didn’t help.

My dealer looked several times to this and is willing to help, but still could not find the cause of the vibrations.

In my search for finding a resolution I found a garage specialised in vibration problems. I brought my car to them and they installed vibration sensors so they could exactly measure which vibrations there were and where they come from.

Vibrations are measured in micro G and normal, acceptable vibrations in a car could go up to max 6 micro G. Vibrations up to 8 micro G are marked as disturbingly, up to 10 micro G are marked as uncomfortable and above 15 micro G as completely uncomfortable.

All vibrations in my Explorer were perfectly under 5 micro G, except the vibration at driveshaft frequency.

The driveshaft of my Explorer caused vibrations up to 17 micro G. After that conclusion they have tried to balance the drive shaft and the best possible they could reach was a drive shaft vibration of 7 micro G. A big improvement and maybe even an acceptable result, but then the next day, just before I would pick up my car again they made a final test drive and the driveshaft vibrations were measured above 12 micro G. Normally this value should not be different then the day before.

Conclusion was slack/tolerance in the CV joint or inlet of the differential causing a variable imbalance in the driveshaft.

With this result report I went to my ford dealer and they installed a new driveshaft. (delivery time of the new drive shaft was 6 months!!!)

The new driveshaft did bring an improvement, but I still noticed annoying vibrations. Still above 30 mph and still the intensity not always the same.

A few weeks ago I brought my car again to the vibration specialist and let them do the same measurements again. The new driveshaft causes vibrations up to 9 micro G. They balanced the driveshaft and they reached a fantastic result of 2 micro G. Then the next day…. checked again and it was up to 7 micro G.

It seems to be there is some variable imbalance in the CV joint of the drive shaft. Like there is some grease or oil in the cover of the CV joint which during the night drops down by gravity and make an imbalance. It is a thought and we are not sure it is really like that, but it seems like it.

My dealer don’t believe this could be possible. I must say he is still working on it but unfortunately he was not willing to remove the cover of the CV joint to see if this could be possible.

I have a very noticeable vibration that feels like it is in the center-to-rear of the car at 37-42mph then it goes away at higher or lower speeds. No vibration in the steering wheel, but you feel it in the seat while driving it. It doesn't matter what drive mode it is in nor what gear. It is present during acceleration, deceleration or cruise. Put it In manual mode you can feel it in multiple different gears and nothing changes. It is still present.

The vibration feels similar to a center support bearing going bad on something like a f250 driveshaft.
Anyone experienced this? Does anyone know if there is a known issue prior in prior years that sound similar?

Hi all, I have the EXACT same problem with my Limited. The dealer has had my Explorer for 2.5 months THIS TIME. A total of 6 months combined. MoCo told them to replace 2 different parts of the driveshaft assembly, not sure which parts (did not correct the issue), and NOW MoCo told them to replace the tires to see if that's the issue... REALLY. Its not the tires.

One thing mine does that I didn't read here is that my vibration does not always exist, and when it does the intensity of it can me mild or down right hateful. Anyone else?

3 people at my dealer said I should Lemon Law it. I am talking to an attorney right now. Ford is fighting by saying I didn't initiate a buyback in the first 12 months. Ohio law says I only have to have the vehicle in for this issue by the 12th month.

My issue started about 3 months after I bought it.

For the folks saying they were told its an underpowered engine, I still get it will driving on level ground or a slight decline, no power needed for that. It also happens if I am on gas or battery power, so that's not it either.

Since many of you on this thread have the 20" wheels, is there a chance you have the self seal Michelin tires?

@weigeo1 Now that the temperature is getting lower, have you experiences the vibration return? I'm looking for a solution as well, the vibration is terrible between 37 and 45. The dealer does not seem to know what to do, so I'm looking for input from other hybrid owner.
Thanks!
