July 2025 update.
Brought the vehicle in for pre-long distance travel service.
Oil change plus tire rotation.
In some miraculous fashion, the tire rotation completely disintegrated the vibration. I can drive the vehicle now close to 90 miles an hour and the vibration is nearly...
Picked the Expy up on Thursday evening last week. Took the Stealth to Gainesville, FL from Miami, FL to witness compete destruction. My service rep said the field engineer stated it was a 'balancing issue'. Driveline was fine. They road force balanced the Defenders...
I must say that it was...
It is ironic that I was about to post this right now. I dropped off my 2024 stealth with this slightly improved but remaining vibration issue at 73+ MPH. I opened up a case a few days ago with Ford customer service and my service representative, took the car in for an A-to-Z service with focus...
Spoke with the Ford customer service specialist who was attentive and seemed interested to find a resolution. She suggested that I find an independent dealership to do an analysis because dealerships are “privately owned.”
She stated that I should be eligible for reimbursement for the tires...
Update: independent mechanic drove vehicle up to 85 MPH. Identified vibration. First impression after history of tire balancing and tire replacement with Michelin defenders is that it is the Dr. train. He’s going to put it on a lift and take a look at all potential symptom generators.
I have...
Deflation level 6. Pushed it past 80MPH and the passenger seat started vibrating. It’s improved with the Defenders but there is larger issue with this vehicle’s engineering and configuration. Hitting independent mechanic in the AM. Will have him lift it and test. He will also drive it.
If no...
You will notice an immediate and visceral difference in the vehicle. Ride quality and handling will be an immediate upgrade. The Michelin were able to corral about 80% of the vibration in my vehicle.
There is a very fine vibration in my vehicle after 73 mph after putting Michelin Defenders on. It’s livable but still unacceptable to me. I’m going to bring the vehicle to an independent mechanic to inspect the driveshaft. I will literally ask him to lift a vehicle and observe and test for...
Update: after an additional 500 miles after
installation of the new Michelin shoes… there is a slight perceptible vibration at 75+ MPH. I almost want to say that this is normal for a vehicle built this way at this weight. I believe it has a bit to do with the low profile side wall on these...
4 Michelin Defender LTX M/S 2 tires on.
Completely different riding vehicle. Even motionless is just ‘sits’ better and tighter.
This is a new car. Vibration not detected above 73MPH.
Out the door for $1,323. (Plus $86,455 for a new Expedition Stealth)
