Need 1991 Chevy Silverado 1500 ball joints, control arms, hubs, or a front-end kit? 1991 is GMT400 C1500/K1500 / Silverado trim (1988–1998). 1999–2006 GMT800 Silverado 1500 uses different knuckles and many different arms. 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.

What usually brings people here
- Low-speed clunk over bumps or driveways → ball joint or sway link (K6292). Most shops prefer replacing the control arm as a complete unit with the joint already pressed in.
- Wander, loose steering feel, or inner-edge tire wear → outer/inner tie rod (ES2004S) or a worn control-arm bushing.
- Growl or rumble that rises with road speed → wheel hub/bearing (515001).
Key SKU choices

While you’re in there
While you’re tearing into the front end, inspect the matching side and the sway-bar links — one-sided wear is common after a hit or a long alignment delay. Confirm the hub (515001) if you have a growl that rises with road speed.
Shop notes only — not a service manual. Use the factory procedure or a Haynes/Chilton manual for wrench work, torque, and safety steps. Leave a comment with drivetrain, suspension type, and the symptom if you want a part-number check.
