Experiencing SEVERE Death Wobble since August 2024, problem continues today at speeds of 60-70mph on curve and/or hard bump in roadway. Mechanic has replace all front end suspension and steering ‘wear parts’. Have replaced all 4 shock absorbers. Replaced all rubber body bushings, which were rotted or partially disintegrated. Problem still persists. Mechanics have no solutions and have given up. I am afraid to drive my truck over 50mph. Help.
