2020 Ford F-350 SD suspension problems

Filed Dec 9, 2025 · Steering, Suspension · CA

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.

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 federal safety agency nor Ford has/is addressing.

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.

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.
