Quite a bit can fall under this topic: shocks, struts, springs, bushings, control arms, torsion bars, drag links, strut rods, and stabilizer links, just to name a few. These components make up your vehicle’s suspension system. Over time, these parts can wear out and end up causing noises. What you would notice as a driver are things like rattles or thumps when going over bumps or rough roads. You might even notice a problem with your vehicle’s handling. If you notice any of these things, it's worth checking out your suspension for any problems.
