Introduction: Lifted Doesn’t Have to Mean Unstable
Installing a lift on your Chevy Square Body seems like a no-brainer—bigger tires, improved clearance, and off-road capability. But many owners soon experience wandering steering, sudden wheel jerks, or that terrifying “death wobble.”
This is bump steer, and it’s extremely common on lifted 1973–1991 K5 Blazers, K10/K20 pickups, and Suburbans. The culprit isn’t worn-out parts or sloppy installation—it’s the factory steering geometry, which GM never designed for lifted ride heights.
