5 Symptoms of a Bad Control Arm Bushing (and Replacement Cost)

Just as every skeletal system has cartilage to cushion and align bones at a joint, every vehicle has control arm bushings at the joints between the upper and lower control arms and the vehicle’s frame.

These bushings are comprised of a cylinder of rubber or polyurethane bonded to a larger and a smaller cylinder of metal on the outside and inside areas, respectively.

The control arms are the pieces of metal which connect the vehicle’s frame to the steering knuckle, where the wheels and tires attach. These are critical to steering and suspension of the vehicle.
