Sway Bar Link
A suspension rod that connects the sway bar (anti-roll bar) to the control arms or struts, reducing body roll during cornering.
A sway bar link (or stabilizer link) is a small suspension rod that connects the ends of the sway bar (anti-roll bar) to the vehicle's control arms or struts. The sway bar is a metal bar that runs across the chassis, and its job is to reduce body roll and sway when cornering by transferring suspension force from one side of the vehicle to the other.
Sway bar links feature small ball joints or rubber bushings on each end to allow for suspension travel. These joints allow the link to twist and bend as the suspension moves up and down over road imperfections, while still transmitting torsional forces to keep the vehicle flat during turns.
Because they are constantly active, sway bar links are among the most common suspension wear items. Over time, the rubber boots on the link joints tear, allowing grease to leak out and dirt to enter. This leads to play in the joint, resulting in a distinct metallic clunking, rattling, or knocking noise from the suspension, particularly when driving over bumps, speed bumps, or turning corners.
Worn sway bar links degrade handling stability and passenger comfort. Replacing sway bar links is a straightforward service that restores quiet suspension operation and crisp cornering performance. It is always recommended to replace links in pairs (left and right) for balanced handling.
