Suspension Control Arm
Control arms often don’t fail on their own, although their associated bushings can break or wear causing a clunk noise when your 1980 Volvo goes over bumps or changes speed rapidly—whether braking or under hard acceleration. Control arms can also sometimes become bent, causing your vehicle to pull to the left or right.
