#Control arms Edgemead

Control arms, also sometimes referred to as a arms because of their shape, are vital components of a vehicle's suspension system they act as hinged links that connect the chassis of the car to the wheel hub assembly or steering knuckle   there are typically two control arms per axle, one upper and one lower they work together to allow the wheels to move up and down as the car travels over bumps and uneven road surfaces this vertical movement helps to maintain proper tire contact with the road, which is essential for safe handling and stability control arms also play a role in maintaining wheel alignment the way they are mounted to the chassis and the wheel hub assembly determines the camber, caster, and toe angles of the wheels these angles are critical for proper tire wear and vehicle handling control arms are typically made of forged steel for strength and durability they are attached to the chassis and wheel hub assembly with bushings or ball joints, which allow them to pivot and move freely the bushings and ball joints can wear out over time, which can lead to a number of problems, including: * uneven tire wear * vibrations in the steering wheel * a loose or clunking feeling in the suspension * difficulty steering
