Need 2003 Chevy Silverado 1500 ball joints, control arms, hubs, or a front-end kit? 2003 is GMT800 Silverado 1500 (1999–2006). GMT400 C1500/K1500 (through 1998) and 2007+ GMT900 are different front ends. 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.
