Signs control arms are wearing down
Like any car component, over time, control arms wear down and need to be replaced. Hawley says many control arm assemblies wear down every 90,000 to 100,000 miles.
Control arms can bend or break when driving over large potholes or bumps, while brushings can also wear out on their own.
“People will start seeing tires not wearing properly,” Hawley says. “If you get tire wear, you may need to look at the components.”
Auto experts say other common signs the control arm assembly needs to be replaced is if steering wheel is vibrating or there is banging noise while driving over bumps.
