Often called control arms, suspension arms are the cushions to the suspension system that controls noise and vibrations. They offer a smooth and comfortable ride experience even over the bumps. The suspension arm assemblies, in general, wear out between 100,000 and 150,000 kilometers. They can wear or bent even during a car accident.
Symptoms of bad or failing suspension arms are steering wheel vibration, steering wandering, clunking noises, etc.
