2020 Ford F-350 SD suspension problems

SUSPENSION

This has occured multiple times. While driving on freeway at speeds between 65 and 75 MPH and hitting rough asphalt, the vehicle begins shaking violently, almost to the point of losing control. It will only stop if I slow down to under 40 mph or stopping altogether. This has been very frightening when it occurs in traffic on freeways. It seems to occur mainly when on a curve.

Death wobble experienced in 2023 at 64 k miles. Had to purchase stabilizer bar from dealer. Had another death wobble incident in April 2024. Dealer replaced same stabilizer bar again. This design is very dangerous empty but when pulling a bid horse trailer loaded with 3 horses could be catastrophic.

SUSPENSION

Extreame front-end vibration ("aka" death-wobble as described for other F250 and F350 pickups on Google). Driving 60mph on 65mph limit highway. Small bump on road. Truck starts severe vibrations from the front end. No steering control. Slight drift into left lane. Another car in the lane left to me had to break to avoid me. Vibration would not stop until I applied brakes and the truck speed was 30mph. Both the loss of steering, and the necessary reduction in speed was extreamly dangerous. Upon searching the internet it appears this is a common problem with Ford F250 and F350 trucks that neither the NHTSA nor Ford has/is addressing.

SUSPENSION

Repeated “death wobble” where the steering components oscillate rapidly left and right causing a lack of steering control. One repair attempted. Later occurrence and another repair. A third event, this time while pulling a 14,000 pound 5th wheel trailer. At about 63 mph the wobble started. I braked, the truck pulled left and I could not maintain my lane. An 18-wheeler behind me moved to the left lane due to my braking and we almost collided due to my not being able to steer. I did get it under control to get back in my lane and avoid the collision. This has been worked on by two different dealers and is about to be looked at again by the original dealer. Almost every front-end component has already been replaced.

My truck starting shaking really bad while driving after 45 miles per hour. I went to the repair shop today and they told me it was the death wobble. Could have lost control of truck as it was very terrifying.

SUSPENSION:FRONT

The contact owns a 2020 Ford F-350. The contact stated while driving approximately 58 MPH, the steering column started to vibrate excessively. The contact was able to pull over safely. There was no warning light illuminated. The vehicle was taken to a local dealer to be diagnosed; however, the mechanic was unable to determine the cause of the failure. The manufacturer was not informed of the failure. The failure mileage was approximately 19,000.

SUSPENSION

While travelling down the highway at approximately 65mph, came in contact with a rough patch of road, causing the front suspension and steering to shake violently, nearly resulting in a loss of control. This persisted for approximately 30-60 secs, until slowing vehicle down to about 50mph. This is the second time this has happened, within the past 3 months. The vehicle has all new tires, and is serviced and maintained regularly.

I PURCHASED THIS TRUCK ON 09/23/20. AT DELIVERY THE STEERING WHEEL WAS NOT ALIGNED CORRECTLY AND HAD TO BE ADJUSTED. TRUCK HAS HAD A CONSTANT VIBRATION THAT IS FELT THRU THE STEERING AND BODY. THE VIBRATION INCREASES WITH SPEED. AT 1031 MILES A REPAIR ATTEMPT WAS MADE THAT WAS UNSUCCESSFUL, AT 3225 MILES AGAIN A FAILED ATTEMPT WAS MADE AT CORRECTING, AT 3735 ANOTHER FILED ATTEMPT. AT 8156 ANOTHER FAILED ATTEMPT. AND AGAIN AT 8934 ANOTHER MORE EXTENSIVE REPAIR ATTEMPT WAS MADE WITH NO POSITIVE RESULTS. I WILL UPLOAD ALL REPAIR WORK ORDERS. THERE IS A SERIOUS PROBLEM IN THE DRIVETRAIN OF THE VEHICLE THAT FORD AS OF YET HAS BEEN UNABLE TO CORRECT. THE VIBRATION IS CONSTANT AND AT HIGHWAY SPEED HAS MADE PEOPLE CAR SICK. I AM FEARFUL THAT THERE IS A FAILING COMPONENT IN THE TRUCK THAT WHEN IT FINALLY BREAKS WILL CAUSE A SERIOUS ACCIDENT. THEY HAVE USED A VCMM VIBRATION ANALIZER THAT LISTED A HOST OF POTENTIAL PROBLEMS AND IN THEIR WORDS THE RESULTS WERE MISLEADING. THIS IS A HEAVY DUTY TRUCK THAT I FEAR TOWING MY TRAILERS WITH BECAUSE THEY CAN'T TELL ME WHY IT HAS THE VIBRATION. I ALMOST BELIEVE THAT THEY KNOW THE PROBLEM AND WON'T DISCLOSE IT TO ME. THE MOST CONCERNING STATEMENT MADE IN THE REPAIR ATTEMPT IS THAT THEY COMPARED MY TRUCK TO AN INSTOCK UNIT AND IT DRIVE COMPARABLE.
