Answer: There are several things you can look for to determine if you need a new sway bar. First, the easiest sign is when your vehicle sways too much when you are taking turns. Second, when you are passing an 18-wheeler or if one is passing you, your vehicle will sway from the 18-wheeler’s crosswinds. Lastly, when turning your vehicle is difficult and you have to overcompensate for excessive swaying, your sway bars should be checked. Any of these signs can mean that your sway bar is loose or damaged, and you should have your sway bar inspected by a professional. You should also occasionally check your sway bar and the bolts that link it to your vehicle to make sure everything is in good shape and not damaged.
