Case Study 3: 2018 Ram 1500
This case study involves a 2018 Ram 1500 experiencing death wobble at speeds above 65 mph. The owner reported feeling significant steering wheel vibrations and a sensation of the vehicle being pulled from side to side, particularly on rough roads.
The vehicle had approximately 30,000 miles on it and had been driven primarily on paved roads.
Contributing Factors
- Defective Steering Damper: The steering damper, a component designed to absorb shocks and vibrations in the steering system, was found to be defective. A defective steering damper can fail to effectively dampen vibrations, leading to instability and death wobble.
- Loose Wheel Lug Nuts: An inspection revealed loose wheel lug nuts on one of the front wheels. Loose lug nuts can cause the wheel to wobble, leading to vibrations and instability, particularly at higher speeds.
- Oversized Tires: The vehicle was fitted with oversized tires, which can affect the handling and stability of the vehicle. Oversized tires can change the geometry of the suspension and steering system, potentially contributing to death wobble.
Repair Methods
The repair process involved replacing the defective steering damper with a new one. The loose wheel lug nuts were tightened to the proper torque specifications. The oversized tires were replaced with the original factory-recommended tires.
Effectiveness Evaluation
The repair methods were highly effective in resolving the death wobble. After the repairs, the owner reported a significant improvement in steering stability and a complete elimination of the vibrations. The vehicle has since been driven for several thousand miles without experiencing any recurrence of the death wobble.
