Death wobble is scary. Also it’s usually caused by a combination of things, not just one worn part. The main contributors are usually worn-out tie-rod ends, control arm and track bar bushings, worn ball joints, alignment out of specification, and so on. Also, tires out of balance or mud in the wheels can contribute to death wobble. Fighting it can be frustrating and expensive, but at some point you’ll probably figure it out if you follow our advice.
