Sway bar bushings are critical components of a vehicle's suspension system. They connect the sway bar to the control arm, helping to reduce body roll and improve handling. Worn sway bar bushings can cause a number of problems, including increased body roll, imprecise steering, and abnormal tire wear. Replacing worn sway bar bushings with high-quality parts is essential for maintaining optimal vehicle performance and safety. Consider material (polyurethane for performance or rubber for comfort) and greasing requirements when selecting new sway bar bushings.
