Introduction: The Lifted Truck Dilemma
Lifting your Chevy Square Body promises bigger tires, more clearance, and off-road dominance. But many owners quickly notice a frightening side effect: wandering steering, sudden wheel snaps, or even “death wobble.”
This is bump steer, a common issue in lifted 1973–1991 K5 Blazers, K10/K20 pickups, and Suburbans. The root cause isn’t faulty parts—it’s factory steering geometry, which GM never designed for lifted ride heights.
