Truck shakes violently at 65mph and higher. Replaced tires, rims, suspension, had the ford dealer check it many times. Took it to a mechanic shop and come to find out the driveshaft is making my truck shake. I have video of the rear end/ driveshaft, and transmission/ transfer case and the dealer said my vin number wasn-??t part of the Recall

The rear axel bolt sheared off. I started to hear a rattle called ford to see when I could get my truck in to get it looked at. Got an appointment set up 2 months down the road was the soonest they could get me in. While waiting for that time truck stated to vibrate. I decided to try a tire rotation and I had the rear axel bolt drop to the ground. Not sure exactly when I started hearing the rattle. They safety was the tire could have come off while driving which could have caused an accident which could have caused injuries or death of my family or others. I called ford back they told me to have it towed in so they could look at it right away. So in 4 days my truck will be towed there for inspection. No warning lights about the bolt but I did have one about 4x4 would not engage back on 27/MAR/2023. Ford checked the axel and suspension.

The bolt that holds the rear axle in place sheared off. This seams to be a common issue on the Max Tow equipped trucks, but Ford hasn't done a recall or even placed a TSB. On top of that my truck is out of service for a back ordered part to fix a safety issue.

Vehicle was purchased new 06/08/2021. Since that time it has been back to the dealer 4 times with 3 being for repairs to the problem. There is a crunching / clanging sound every time a turn is made on an incline or decline. The vehicle has been inspected and gone over with body bolts loosened and re-tightened to factory specs to no solution. It was taken back again and now the dealer thinks it is something with the springs. The truck has been with the dealer a total or 27 days as of this date. ( 08-21-2021 ) and repair attempted 3 times. The dealer is not sure if springs are the problem, just chasing possibilities down. I have a loaner which myself and my wife heard the same noise starting. We feel unsafe with this vehicle and Ford seems to be passing the buck although the dealer rep believes it is time for a buy back.
