As part of your vehicle's suspension, the control arm links the wheel hub to the chassis. Control arms, or A-arms as they are also called, can wear out and cause a bumpier ride than you are used to. As opposed to your car's shock system which holds things up, your control arm is flexible enough to adjust and compress the weight of bumps so that you don't feel them when you ride. It keeps your car riding smooth and your passengers happy. Contact us to find out more about control arms and your vehicle's suspension!
