Front Thrust Arm - Left

Front left control arm with factory installed bushing and ball joint.

Failed control arms commonly cause vibration and shaking that is transmitted through the steering wheel, increasing with speed or braking. Symptoms may also include suspension noises, incorrect steering alignment, and accelerated tire wear.

ECS suggests that control arms be replaced as pairs (both left and right sides) for best results, and that all related suspension components be inspected for wear, binding, or looseness.
