Control Arm Operation And Problem Finding
Iron cast control arms are the components that connect a car's suspension to the chassis. Although iron cast control arms come in many shapes and sizes, they are easy to identify or spot. They are visible metal structures that extend from the body to the wheel assembly.
Iron cast control arms come in different designs. There are "A" shaped types, which have also given rise to other names such as "A" arms, "A" frames, and "wishbones." They look like triangles and are one of the most common designs for these vehicle parts. The narrow end of the "A" iron cast control arm connects to the wheel assembly, and the wide end connects to the car's frame. The narrow end usually has a ball joint as the pivot point, and the wide end has a bushing.
Some iron cast control arms are "L" shaped. Like the "A" design, they are connected to the steering knuckle on one end and pivot on a ball joint on the other end. Another iron cast control arm design is the single axis. It uses the same connection as other iron cast control arms, which is a ball joint on one end and a bushing on the other.
Signs of a control arm problem:
Vibration:
Worn suspension control arm bushings can cause the wheels to vibrate when you press the gas pedal. The same goes for cornering. Wheel wobble may be transmitted all the way to the steering wheel. If you experience steering wheel shudder, you may want to inspect the suspension control arms to see if the bushings are worn. Other car parts can also cause steering wheel vibrations. Before confirming suspension control arm damage, determine if they are responsible.
Steering wheel shakes:
In addition to vibration, a damaged suspension control arm can cause the steering wheel to wobble from side to side. Steering wobble may be a sign of worn bushings or ball joints and excessive movement. This reduces driving comfort and may result in loss of vehicle control. Once this symptom occurs, it is highly recommended that you replace the damaged suspension control arm component immediately.
Abnormal noise
Again, this is a sign of excessive wear on the Automotive suspension control arm bushings and ball joints. Typically, bushings restrict Automotive suspension control arm movement. The ball joint also limits most rotation. Wear can increase movement and cause the metal parts of these joints to collide. This can cause the suspension to squeak, especially when accelerating, cornering, or driving over rough road conditions.
Uncomfortable journey
The Automotive suspension control arms are hinged on bushings to dampen vibration and help reduce the severity of bumps or rough terrain. The other end is pivotally connected to the ball joint to make the wheel move up and down smoothly. When these parts become damaged, passengers begin to feel potholes and bumps in the road.
If you notice these signs, it may be time to install a new Automotive suspension control arm.
