"Death wobble" is a common Dodge truck front end issue and also a sign of some thing bad/shot/worn out or loose. Insp things like radius arm bushings, shocks, ball joints, wheel bearings being way loose, bad tire from a separating tread. Tie rod ends, if it happened under braking maybe you have warped front rotors? Steering shaft rag joint, way out front end alignment. you know just the little things.
