LOWER CONTROL ARMS

What Are Control Arms?

Control arms, sometimes called “A arms,” are the core of your front suspension system. In simple terms, control arms are the link that connects your front wheels to your car. One end connects to the wheel assembly and the other end connects to the framework of your car.

When To Replace A Control Arm?

There are several reasons why a control arm needs to be replaced. The most common reason is when a ball joint wears out, and it cannot be replaced separately. Often a ball joint comes with a control arm as one unit.

A worn-out ball joint can pop out causing the vehicle to lose control while driving. This means that a vehicle with a worn-out ball joint is unsafe to drive. Unfortunately, symptoms of a worn-out ball joint are rarely noticeable. Your mechanic can check ball joints, control arms and other components during a regular service, but this can only be done when a car is lifted on the hoist.

Worn-out or cracked control arm bushings is another reason to replace a control arm, although in many cars, the bushings can be replaced separately. Another reason to replace a control arm is when it has been damaged or bent after hitting a pothole or curb.
