Control arms are essential suspension components that connect the vehicle’s frame to the wheel hub, allowing for smooth up-and-down movement of the wheels while keeping them properly aligned. They help maintain stability, absorb road shocks and support steering precision. Equipped with bushings and ball joints, control arms ensure a comfortable ride and proper handling. Worn control arms can cause clunking noises, uneven tire wear and poor alignment, making timely replacement important for safety and performance.
