How Long Does a Sway Bar Link Typically Last?

[Elisa]

Sway bar links have an unpredictable lifespan, as it largely depends on the vehicle's usage conditions. Generally, they last around 60,000 kilometers. Here's a detailed explanation: 1. Function of sway bars: When both left and right wheels pass over identical road bumps or potholes, the sway bar remains inactive. 2. Body roll suppression: However, when left and right wheels encounter different road surface irregularities (i.e., when wheel heights differ), the bar twists to create anti-roll resistance that counteracts body roll. 3. Activation conditions: The sway bar only engages when left and right suspensions move asynchronously - either due to uneven road surfaces or during cornering maneuvers. When suspensions move synchronously up and down, the sway bar doesn't function.
