Locking hubs seized up at 17,000 miles. could only turn them with a wrench. the coating around the hub was bubbling with corrosion from inside. this problem has occurred on my previously owned f250 king ranch. dealership was aware of this problem and stated it was common.
October 8, 2018 at 3:45 pm heading north bound on us highway 55 at mile marker 191.8 towing a fifth wheel rv, hit rough pavement which caused uncontrollable oscillation of the steering wheel and violent shaking of the entire vehicle. you must slow the vehicle to under under 10 miles an hour to regain control. this same type of situation happen on august 4, 2018, which i returned the vehicle to the ford dealer who stated they could not find anything wrong, because they could not duplicate the issue.
Uncontrollable steering after driving over expansion joints on the highways or rough roads or streets. once you drive over these areas, the steering wheel begins to violently shake to the left then the right. the truck is shaking violently and makes it difficult to control the vehicle. you must slow down to almost a stop to stop the violent shaking and regain control of your truck. this has happen two times in a row and i went straight to the ford dealer who replaced parts. on the second time this happen, i had to cut between the highway workers back blocking truck and the highway workers repairing the road because i could not control the vehicle at the highway speed. it has happen again and the truck is back in at the ford dealer.
The vehicle was parked on an incline, with the front of the truck pointing up the slope. the transmission was shifted from drive to neutral, the parking brake was applied, and then the transmission was shifted from neutral to park. the vehicle was left unattended, and shortly after that, it rolled 10-15 feet backwards, with the transmission in park, and the parking brake fully applied. it was found stopped on level ground. upon realizing what happened, i repeated the parking process using the same shift sequence, d-n-p, with the same results. additionally, i tried parking the truck pointing down a slope. in this situation, the truck rolled forward, and had to be stopped using the brake pedal. i immediately took the truck to the dealer who i bought it from. they could not replicate the problem and took no action to investigate or repair the transmission.
While driving at 60 to 70 miles per hour you get a slight shimmy in the back end. as you progress the shake gets worse. the ford shop where i live has a rush in rush out work ethic, they don't listen to the one paying the bills. i have tried several shops to find the problem, no results. *tr
