Usually the fist thought is a strut or spring, but sometimes it's the sway bar link! In this video, Sue points out how and why a sway bar link might break and what kind of problems it can cause! Sway bar links connect the sway bar, or anti-roll bar, to some other suspension component, like a strut or control arm. These links usually have a swivel joint so that they can move with the articulation of your vehicle's suspension. Over time the joint can wear down and break, leaving the bar of the link swinging free to clunk and bang on all sorts of things! While it may seem like a simple problem that you can put off, there is real potential for damage, so make sure to give this one your attention as soon as you can!
