Keep the rear suspension located and quiet with the Beck/Arnley Suspension Trailing Arm 102-6136, a direct-fit replacement for the 2006-2010 Kia Optima. This is the rear right trailing arm — it links the rear wheel assembly to the chassis, helping locate the wheel and control its fore-and-aft movement while the integrated bushings isolate road vibration. If worn or damaged bushings are causing clunking, looseness, or inconsistent rear-wheel alignment, replacing this arm helps restore the intended location and cushioning.
