These parts wear out rather quickly and most vehicles have a sway bar of some sort. The installation is very simple and is similar on most makes and models.
+Eric M visual inspection is best. Just look underneath find where the sway bar connects to control arm and see if it's still connected. Mine were just floating and rattling away. What it does is keep the truck body from swaying back and forth too every time you have a bump that makes it want to rock.
