Multiple instances of the Death Wobble / Sustained Steering Wheel Oscillations while travelling in the Memphis, TN area. Have contacted the local Ford Service department and they plan to replace the Steering Link Damper. Suspect that this is only a short term band aide. Wife has history of Costochondritis, truck shook so violently it reinjured her during the last DW/SSWO event. Vehicle has less than 28,000 miles on it.
