If your vehicle is showing whole car shakes violently after hitting a bump (death wobble), here are the most likely causes and the parts you'll need to fix each one.
Loose tie rod ends or a worn drag link allow the front wheels to oscillate left and right independently after hitting a bump. This is one of the most frequent primary triggers for death wobble.
The track bar and control arms keep the front axle centered under the vehicle. If these bushings wear out, the entire axle can shift side-to-side violently when upset by a bump.
Ball joints act as the pivot points for your steering knuckles. When they develop excessive play, the wheel can wobble on its vertical axis, contributing to the violent shaking.
Often occurring after installing a lift kit without geometry correction, a low caster angle makes the steering inherently unstable and highly prone to oscillation.
A steering stabilizer acts like a shock absorber for your steering. While a blown stabilizer doesn't cause death wobble on its own, it fails to dampen the vibrations that trigger it. Replacing it often temporarily masks the true underlying worn parts.
Severe play in a wheel bearing allows the entire wheel and tire assembly to wobble loosely. This can act as the catalyst that sets off the suspension oscillation.
A severely out-of-balance tire, separated tread, or bent wheel can create the initial harmonic vibration that excites the loose suspension components into a full death wobble.
