1978 Chevy Silverado 1500 Suspension Parts

Need 1978 Chevy Silverado 1500 ball joints, control arms, hubs, or a front-end kit? 1978 is squarebody C10/K10 / C1500-era 1/2-ton (1973–1987). 1988–1998 GMT400 C1500/K1500 / Silverado trim is a different front end. This is not 2500, not Suburban, and not Express.

A clunk at low speed is usually a ball joint or sway link. Wander or inner-edge tire wear is more often a tie rod or a worn control-arm bushing. Most people replace the control arm as a complete unit with the ball joint already pressed in.
