Shocks and struts play the biggest role to the stability and control of your vehicle. These parts are crucial to stopping, turning and swerving at the exact moment that you need to. Shocks and struts that are wearing down causes swaying, bounces and overreacts to corners as you stop or accelerate over bumps and uneven surfaces. Worn shocks and struts make it more difficult for the driver to maintain control of the vehicle, causing the driver to constantly make steering corrections while driving to compensate.
One worn shock can increase your vehicles stopping distance.
